SOUTHERN STINGRAYS: BAHAMAS REEF FISH (41)

Anyone who has scuba-dived or snorkelled around the bright coral reefs of the Bahamas, or hunted bonefish out on the Abaco Marls will have come across Southern Stingrays Dasyatis americana. And there are certain places (eg Manjack Cay) where you can actually feed them – and not come to any harm

FEED THEM? AREN’T THESE GUYS LETHALLY DANGEROUS CREATURES?

Southern Stingrays, Bahamas (Melinda Riger / Grand Bahama Scuba)

The name that always comes to mind in connection with stingrays is poor Steve Irwin, the charismatic Australian wildlife expert who was tragically ‘stung’ over his heart as he swam close over a ray while filming underwater. But this was, it would appear, a dreadful combination of circumstances with a terrible outcome.

Southern Stingrays, Bahamas (Melinda Riger / Grand Bahama Scuba)

The ray’s stinger is in fact an erectile venomous barbed spine near the base of the tail and not on the end of it (as one might expect). But these creatures are not out to harm you – though of course when you are in their environment you should accord them the respect that they merit.

Southern Stingray (Tomas Willams, wiki)

If you are walking / wading in the water, avoid the risk of accidentally treading on a ray. Best to shuffle your feet forward in the sand; if there’s a half-concealed ray feeding or resting on the bottom nearby, it will swim away peacefully. I took the photo below while bonefishing on the Marls; the ray directly ahead slowly makes off as the skiff drifts closer. The next one is of a ray with its young – completely aware of us as we glide past to one side, but not especially bothered.

If you are swimming, snorkelling or diving, don’t get too close – especially by swimming directly over a ray (apparently Steve Irwin’s mistake, so that he was struck right in the chest by the stinger when the ray reacted).

Enough of the potential dangers. The southern stingray is a magnificent creature, as Melinda’s wonderful photographs show. She spends half her life underwater and I’m not aware that she has had a problem with a ray.

Like many larger sea creatures, stingrays need help with their personal care – the removal of parasites, dead skin and so forth. And so they make use of the services offered by small fish like gobies, wrasses and shrimps at a CLEANING STATION. Here are 2 photos of rays doing just that. You can see the tiny fish by the reef, going about their work. There’s a mutual benefit in this symbiotic relationship, in which it is understood that the cleaners are unharmed. Indeed, they will often enter the mouths and gills of a fish to clean… including the teeth. So there’s dental hygiene on offer too…

GET ME A ‘CUDA – AND MAKE IT SNAPPY…

GET ME A ‘CUDA – AND MAKE IT SNAPPY…

It’s probably fair to say that barracudas are among the less kindly-disposed of the denizens of the flats and reefs of the Bahamas. They certainly rank high on the Rolling Harbour Tooth Avoidance Scale. The seemingly random nature of the razor sharp dental arrangements – different sizes, different angles, different directions – does not inspire confidence. 

Barracuda, Bahamas (Melinda Riger / Grand Bahama Scuba)

The worst fishing injury I have picked up so far – aside from multiple terrible injuries to pride from botched casts, mistakes, missed takes and lost fish – has come from a large ling. What I didn’t know until I had been cut when my finger went into its mouth was that the teeth are coated in anticoagulant. I bled all over the boat and spent the rest of the day getting through a large roll of paper towel and several improvised bandages (J-cloths). That wiped the smug smile off my face – pride in the catch came before a notable fall in my standard-issue blood quota.

Ling caught off the Dorset coast (Keith Salvesen)

Barracuda, Bahamas (Melinda Riger / Grand Bahama Scuba)

When bonefishing in the shallow waters around the coast of Abaco, there are always ‘cudas to be seen. They are not the main target fish, but the boats always have a spinning rod in them, just in case… At some stage in the day, some people find it hard to resist the urge to chuck out a lure when ‘cudas are about. It’s not something I generally do, though occasionally my fly gets intercepted by a practice-sized ‘cuda. 

A learner ‘cuda that took a bonefish fly

Earlier this year I was in a boat fishing with the legendary Robin Albury, a guide who generally doubles my usual modest catch rate. My boat partner and I were taking a lunch break, with an open cool box of snacks between us and a Kalik in our hands. Robin went to the sharp end with the spinning rod on the off-chance. In a flash he had seen a big ‘cuda, chucked out the lure onto the creature’s nose and caught it, almost in one movement. I put down my beer to watch the entertainment. Robin decided otherwise, and simply handed me the rod to play the thing. And boy, was that fun. I didn’t get the kudos of making the hook-up, but I had plenty of work to do… It took an excitingly long time to bring the strong and vigorous fish to the boat. Robin got to hold the fish, of course – after my ling experience, I was happy enough to let him mess with the dental arrangements.

BALD EAGLE ON THE ABACO MARLS: EXTREMELY RARE SIGHTING


BALD EAGLE ON THE ABACO MARLS: EXTREMELY RARE SIGHTING

On March 22nd a friend of ours, James, was bonefishing far out on the Abaco Marls when he was astounded to see the unmistakable appearance of a bald eagle Haliaeetus leucocephalus flying above him. His boat partner and guide Joe also saw the bird. James is a very experienced birder, and has seen plenty of bald eagles over the years. He was not to know, at the time, what an exceptionally rare sighting this is. The location was in the area of  Big Pine Point.

SIGHTING REPORTS

If you are out on the Marls and see this bird, please can you add a comment to this post or contact me at rollingharbour.delphi@gmail.com, giving the date, time, approximate location… and if possible attaching a photograph. Any reports will add important data to the archive for the birds of Abaco, and of the Bahamas generally.

PREVIOUS ABACO SIGHTINGS

I checked Tony White’s compendious checklist compiled for BIRDS OF ABACO that contains all species recorded for Abaco since 1950. He categorised the Bald Eagle as a ‘V4’,  indicating a vagrant species with a handful of irregular sightings – ever. I then contacted Bahamas bird guru Woody Bracey to check the details of earlier sightings. The answer is:

“Bald Eagles were sighted on Abaco three years running 2000-2002. In each instance it was over the Christmas Holiday period (12-20-1-10). I saw one in 2002 from the overlook near Treasure Cay looking out over the marls. Betsy (Woody’s wife)  saw one over the chicken farm fields in 2001 but I missed it”.

Some people might mistake the Caribbean subspecies of Osprey (an all-white head) for a Bald Eagle but as Woody points out, “their flight and shape are very different”

‘BONEFISH CHASE’: A SKIFF RIDE FROM CROSSING ROCKS

‘BONEFISH CHASE’: A SKIFF RIDE FROM CROSSING ROCKS

Does any ‘fun’ (toxic concept) ever happen around Rolling Harbour? All that detailed business about our little winged friends. All that earnest historic stuff with, like, maps and things. All those fish that are basically just… fish. Ditto the flowers. The prints of Whales (geddit?). But does Rolling Harbour ever truly come alive?

Well here’s a little brief entertainment in a skiff setting off from Crossing Rocks for a day of bonefishing, throwing some shapes along the twisty channel between the jetty and the flats beyond. Anyone who has enjoyed the sometimes exhilarating / sometimes painful (in choppy waves) skiff trips on Abaco to get out to the bonefish grounds will relate to this. You get 2 versions: high definition, with some pretentious music to match the mood. According to me. 

Here’s a smaller version with a more familiar theme (also to be found on the Sidebar of this blog) for those who are allergic to pretentious music… it’s more ‘fun’, in fact.

ROLLING HARBOUR, ABACO: LIFE’S A BEACH & THEN SOME…

Rolling Harbour (the geographical feature) is a gently curving one-mile white sand bay presided over by the Delphi Club, which sits on a 50 foot cliff behind the beach. There are rocks at either end, fish in the sea (including bonefish and, in the right conditions, permit), birds on the shore and shells on the sand. And that’s it…

SAW FISH IN THE ABACO MARLS? NO SURPRISE. SAW A SAWFISH? AWESOME!

SAW FISH IN THE ABACO MARLS? NO SURPRISE. SAW A SAWFISH? AWESOME!

Exactly a year ago, an extraordinary find was made out on the Abaco Marls. Almost disguised against the pale mud under the low water was the first sawfish reported for the Marls. This fish is not merely a rarity in the Northern Bahamas: all species of sawfishes worldwide are IUCN listed as Endangered or Critically Endangered.

Sawfish, Abaco Marls Feb 2014 (Photo: Jacque Cannon)

Here is an account of the discovery reported by FRIENDS OF THE ENVIRONMENT: “On a recent fishing trip in the Marls with local guide Justin Sands, Sam and Jacque Cannon had an exciting encounter. As Justin was poling the flats, with Sam on the bow searching for bonefish, Jacque spotted a Sawfish! Jacque and Justin quickly forgot about Sam and his efforts to catch a bonefish and turned their focus to the Sawfish. This is a very rare sighting and one we are happy there was a camera available to document it…” A couple of weeks later I was lucky enough to sit next to Jacque at dinner at the Delphi Club, so I was able to hear at first hand the story of this amazing find. It also turned out to be the perfect time to sign an early copy of “The Birds of Abaco” for Jacque and Sam… 1900063_10152069487394482_984358031_n

 10 ESSENTIAL SAWFISH FACTS

  • Sawfishes are also known as Carpenter Sharks; their ‘saw’ is called a ROSTRUM
  • There are 7 species in oceans and seas worldwide, including the Mediterranean
  • All populations have declined drastically due to habitat loss, overfishing & pollution
  • The rostrum is used to feel, to dig, to slash & impale or stun its prey, and for defence
  • Sawfishes are nocturnal creatures and spend a lot of time face down on the sea floor
  • Like sharks, their skeleton is made of cartilage and not bone.
  • Some species can grow up to 7m long
  • They are generally unaggressive unless provoked but fight strongly when caught
  • Sawfishes are slow breeders, making population recovery more difficult
  • Babies are called ‘pups’. Their rostrum is flexible and sheathed until after birth

Other sawfish have been seen recently in the Northern Bahamas, though not in Abaco waters. Last summer the Bahamas National Trust posted 2 great images of a Smalltooth Sawfish, saying “BNT was excited to receive these photographs of a Smalltooth Sawfish photographed in the proposed East Grand Bahama National Park – Bersus Cay Area. The sawfish was 12 to 13 feet long and was seen in water that was 2 -3 feet deep. Thank you to Buzz Cox, Island Manager at Deep water Cay for sending us these photos”. Sawfish, Grand Bahama Sawfish, Grand Bahama

CONSERVATION ISSUES

POPULATION DECLINE As noted above, Sawfish populations have declined to less than 10% of historical levels. The Smalltooth Sawfish – seen above – was once prolific in the Atlantic, Gulf of Mexico, Mediterranean, Black Sea and Indo-Pacific. Population numbers of this species are now estimated at less than 5% to perhaps as low as 1% of their historic levels.

THREAT TO SURVIVAL The threats to their existence are many: habitat loss, overfishing, accidental bycatch, rostrum souvenir hunters (good prices can be obtained), taking them for fins (as a delicacy) or oil from their liver (medicinal).

LEGAL PROTECTION Capturing a sawfish is illegal in certain countries, including the United States. The sale of smalltooth sawfish rostra is prohibited in the United States under the Endangered Species Act.  The import for sale of that of any sawfish species is also prohibited. The international trade of sawfish was banned by the CITES convention in June 2007.
For those that want to find out  a bit more detail about these issues, there’s plenty on interesting information in a scientific (but readable) paper from NOAA – click the link below

Time for some footage of these rare and wonderful creatures in the Bahamas. The first is from John Flanagan and was taken during a dive off Bimini in early 2014. He was so surprised by the sight that he nearly forgot to turn on his camera to take a short video… The second is a longer 5 min video taken off Andros by Grant Johnson of “wild footage of the critically endangered Smalltooth Sawfish (Pristis pectinata). The west side of Andros, Bahamas is one of the last places on Earth that still provides vast refuge for this incredible animal”.

Finally, you may be wondering how exactly the sawfish uses its rostrum to stun fish, as mentioned earlier. Watch this short video – see how quickly it moves, for such an apparently cumbersome and dozy creature…

 MARK’S BONEFISH FLIES (MARK 2): THE ABACO CHALLENGE, ROUND 2

Last March I took 6 bonefish flies specially tied by MARK MINSHULL out to Abaco to test on the Marls. They were lovely flies, tied with great skill by a man who can pull beautiful fly-caught fish out of the Thames. I tried them. Far better fishermen than me tried them. The result was a failure that can only be qualified by the word ‘complete’. Mark took the news very well, and promised to redesign some flies that might be more enticing this year. Here is his design report for the Mark 2 version that I received this morning. The links to the first experiment can be found at the end of this post.

JLM BONEFISH SPECIAL MARK 2

Those of you who may have read my previous posts about JLM Specials and Bonefish already know about RH (of Rolling Harbour fame) and his wonderfully generous spirit. He kindly field tested my original pattern with fantastically conclusive results in 2014! The beauty of designing fly patterns is that one can tweak every variable based on feedback received… The basic pattern still holds however the revised editions are a far cry from their predecessors:

This afternoon I completed a set of adapted flies based on RH’s generous report from last time. White and pink, with small flashes of red or orange are my main ingredients and for the streamers, I used varying proportions of elk hair and/or Arctic fox fibres.

I’ll keep you posted of the Outcome in due course. As always – thank you for reading and I look forward to your return.

Here is my own photo of the new Mark 2 flies on a white background to show their subtle differences. I can see at once that I shall have to number them all and remember who is using which, so that the killer variation(s) can be identified… As you will notice, the craftsmanship is terrific. My bet would be on the skinnier ones being the most effective in clear water, but I fancy casting one of the hairier ones across a feeding cloud and dragging it back through the murky water… (which is the only way I’ve ever caught 6+ lb fish – yes, yes, I hear you, that’s pure luck and not skill at all).

Bonefish Flies Mark2

Now I just have to sort out my fly box for next month’s escapades. Some things need to go to make some room – those appalling brown stripy ones for a start, which the guides have chortled at. Or, worse, stared at sadly… Oh, did I mention I also have the little tin with foam in… and that small green ‘Orvisman at Orvis’ fly box from Orvis™… 

The Snowbee Stripping Glove has been thrown to the ground at my feet. The challenge is accepted!

ABACO’S FOUR PROTECTED AREAS: THE PROPOSALS


ABACO (CUBAN) PARROT (Caroline Stahala)

ABACO’S FOUR PROTECTED AREAS: THE PROPOSALS

The latest version of the 40TH ANNIVERSARY OF THE BAHAMAS PROPOSAL FOR THE EXPANSION OF THE PROTECTED AREA SYSTEM OF THE COMMONWEALTH OF THE BAHAMAS has been published. It is a joint proposal by the Bahamas Government, The Nature Conservancy and the Bahamas National Trust. The breadth of the scheme is very ambitious, affecting all the principal Bahama Islands. To understand the objectives and scope of the project, you can see the whole 34-page project by clicking BAHAMAS PROPOSED PROTECTED AREAS 2014 It is in pdf format, so you should be able to save it if you wish to.

Many people will be familiar with the proposals as they affect Abaco. However since the latest version appears to be a final draft, I thought it might be helpful to show the 4 proposed areas of protection and conservation in their present form. These are, in summary:

  1. THE ABACO MARLS NATIONAL RESERVE A vast area of nearly 200,000 acres (300 square miles) of mangrove flats, sandbanks, creeks and wetland habitat
  2. EAST ABACO CREEKS NATIONAL PARK 13,000 acres (20 square miles) of wetland habitat that provides a vital wildlife nursery, and includes blue holes, creeks and a significant area for recreational activities (though Pete’s Pub at Little Harbour may be just outside the zone…)
  3. CROSS HARBOUR PROTECTED AREA 14,000 acres (21 square miles) in South West Abaco, a crucial breeding area for a number of species,including bonefish
  4. SOUTH ABACO BLUE HOLES CONSERVATION AREA  A huge 34,000 acre (53 square miles) swathe of South Abaco to the west of the E D Highway, incorporating 4 inland blue holes and important cave systems, and 13 offshore blue holes. This is an area of mainly pine forest on land and low waters at sea, with an anticipated value for eco-tourism

Here are the BNT maps showing the extent of each area. Far more information will be found via the link to the report given above.

A BONEFISHING CHALLENGE ON ABACO: THE ‘WHICH?’ REPORT


_MG_4668_1280x853_

A BONEFISHING CHALLENGE ON ABACO

In January I posted an article called BONEFISHING ON ABACO: A CHALLENGE IS ACCEPTED. This stemmed from contact online with fisherman and fly tyer Mark Minshull, who kindly tied some flies for me to try on the Marls. In the post I showed pictures of my manky flybox and his immaculate flies. We agreed to see how things turned out while I was on Abaco in March, and  that I would report back…

Mark 1 Specimen Bonefish Flies

THE ‘WHICH?’ REPORT ON MARK 1 BONEFISHING FLIES

We set out to test the efficacy of  prototype ‘Mark 1’ bonefishing flies in the waters of the Abaco Marls. Our testers came from the US (TC & AH), Northern Ireland (AB), and England (RH). All are proficient fly fishermen with experience of several prime bonefishing destinations between them, except for the Englishman RH who was included to add balance to the trials by adding the element of incompetence. His fly box remained an object of ridicule throughout the tests, until he resorted to using a more carefully chosen small fly box containing his most successful flies, some ‘Delphi Club Approved’ flies and the test flies. 

QUALITY All our testers agreed that the Mark 1 flies were beautifully designed and tied. As flies, their quality was rated ‘superb’; ‘bloody good’; and ‘very impressive’. As potential winners for the waters of Abaco, however, there was considerable doubt about the suitability of the pattern for colouring, shape and size.

THE TEST AREA We used the huge area of prime bonefishing territory of the mangrove swamps and sand banks on the west side of Abaco known as the Marls. Our testers were familiar with the waters and all had fished them numerous times. The sea depth, depending on tide, is a few feet at most. The consistency of the bottom is of lightweight, pale coloured mud.

Bonefishing, Abaco Marls Abaco  1

It is usually easier to look out for the shadows of the fish on the light bottom than for the fish themselves, which are often difficult to see in the water. Half-close your eyes and look at this image – the fish almost disappears, but the shadow is clearly visible. It is hard to believe the wonderful colouring of the fish until it is out of the water.Bonefish, Abaco Marls Abaco 2

THE TESTS The initial reservations of the testers unfortunately proved justified in the field. The testers all found that the fish tended not to follow the flies at all, and mostly behaved as if they had not seen them, even with the most accurate casts. The few ‘follows’ observed produced refusals of the fly at the end. Disappointingly, no fly was taken by a single fish throughout the trials.

OBSERVATIONS Our testers had some useful comments. Above all, the Mark 1 flies were undoubtedly of excellent quality and design. They simply were not suited to the waters – or the bonefish – of Abaco. TC thought they might work in Belize. It was thought that larger versions might attract permit. Overall, the Mark 1s were so radically different from the tried and tested fly patterns used successfully on Abaco that the 3 competent fishermen soon forsook the experiment and caught fish using more familiar flies. The 4th tester, lacking any finesse, might have fluked a take against the odds , but even he drew a blank.

THE PROFESSIONALS The Guides in each case had been fishing the Marls since they could walk and hold a rod. They each examined the flies, shook their heads and kept their thoughts to themselves. We interpret this as indicating a tendency for the local guides to doubt the effectiveness of the Mark 1 flies.

RH’s ‘Selected Specimen’ Fly Box

RESULTS ANALYSIS  The flies above show (front row) the 3 versions of the Mark 1 fly; (middle row) the highly effective Delphi Daddy and Delphi Diva patterns, with one random silver concoction of unknown origin; (back row) ; 2 browny / pale patterns plus a shocking pink one that the guides wisely forbade and, below, 3 roughly matching flies that brought great success even for RH this year (including 12 boated and 5 lost in one day), sourced from renowned tackle specialist E. Bay.

CONCLUSION The flies that catch the bones on Abaco tend to be pale and to have ‘streamer’ tails and / or a fair amount of sparkle. A touch of pink seems to be good. Too much pink, not so. Rubbery legs can be very effective (except in the fisherman after lunch). But lovely lifelike dark shrimp imitations are of no interest to the fish of the Marls.

RAYS OF SUNSHINE ON THE ABACO MARLS


Stingrays Abaco Marls 1

RAYS OF SUNSHINE ON THE ABACO MARLS

The Marls of Abaco are prime bonefishing grounds, a vast area of labyrinthine mangrove swamps, sandy islets, channels and shallow flats on the west side of the main island. The fish are wily and powerful, the fly hooks are barbless, and each one caught, retained, boated and swiftly released is a prize. There’s plenty of other wildlife to be seen. Heron and egrets, ospreys, belted kingfishers, wading birds and many other bird species make the Marls their home. In the water, there are snappers, jacks, barracuda, and sharks of various kinds and sizes. These latter range from small black tip, lemon and hammerhead sharks to more substantial contenders, with the occasional massive bull shark to add a frisson for those on a suddenly fragile-seeming skiff… 

There are also rays. I have posted before about the SOUTHERN STINGRAY and the YELLOW STINGRAY Out on the Marls I have mainly seen Southerns as they move serenely and unhurriedly through the warm shallow water. A couple of weeks ago, we were out with the rods when we had a completely new Ray experience. I’m not overly given to anthropomorphism and getting too emotional about encounters, but we all found this one quite moving – even our very experienced guide.

According to our guide, this gently protective behaviour is not uncommon. They may well have been completely unrelated, the large ray tolerating the smaller one accompanying it through the waters and offering a kindly wing in the presence of danger or suspicious objects like us.

AN OSPREY ON THE ABACO MARLS


Osprey - Abaco Marls 3

AN OSPREY ON THE ABACO MARLS

Anglers are not the only creatures out fishing on the Marls. Herons and egrets of several sorts live in the massive area of mangrove swamp, shallow sea and sandy spits that make up the prime bonefishing grounds of Abaco. Yesterday, we were lucky enough to be joined by an osprey. Hooking my ‘Delphi Daddy’ safely into a rod ring, I grabbed a camera and took some shots. These aren’t that great because (a) I normally only take a small cheap camera out fishing (b) the bird was some away off and (c ) my image qualities are variable… These aren’t really worth clicking to enlarge, but I’m pleased to have got some ‘action shots’ of this wonderful bird.

‘IN THE PINK’: ROSEATE SPOONBILLS IN THE BAHAMAS

‘IN THE PINK’: ROSEATE SPOONBILLS IN THE BAHAMAS

ROSEATE SPOONBILLS (Platalea ajaja) are rare visitors to the Northern Bahamas. For Abaco they are classified with the undignified term ‘vagrant’, meaning essentially (a) that you will be very lucky indeed to encounter one, so therefore (b) it is highly unlikely to be worth making a special trip based on the likelihood of seeing one. Try Florida instead.

Roseate Spoonbill WB 60

We saw one once when bonefishing far out on the Marls. It was unmistakeable, but well beyond the effective range of the puny ‘don’t-really-mind-if-it-takes-a-dive’ camera I had with me. The spoonbills in this post were photographed elsewhere in the Bahamas or in two cases, Florida. The wonderful one below of a spoonbill ‘flipping’ a fish was taken there by Ohio bird expert and photographer Tom Sheley.

SPOONBILLS LOOK VERY DRAMATIC IN FLIGHTRoseate Spoonbill WB

Unlike herons, spoonbills keep their necks outstretched in flight. They are most likely to be found in marshes, salt-water lagoons and on mudflats. They are gregarious and mix in happily with herons and egrets, though there is some competition for food. Spoonbills nest in shrubs or trees, often mangroves.Roseate Spoonbill WB 59_IMG_6302 copy 3

Spoonbills tend to get pinker as they get older. As with American Flamingos, the pink colouring derives from their diet, which contains carotenoid pigments.  The colouring ranges from pale pink to loud pinks and reds, depending on age and location. 

Roseate Spoonbill WB 61Roseate Spoonbill BH (from WB)

Spoonbills feed in shallow fresh or coastal waters by swinging their bill from side to side while steadily walking through the water, often in groups. The spoon-shaped bill allows it to sift easily through mud for the edible contents – crustaceans, aquatic insects, frogs, newts and  small fish ignored by larger waders. This  excellent 1 minute Audubon video shows exactly how they feed, with some white ibises for company.

BONEFISHING ON ABACO: A CHALLENGE IS ACCEPTED


Abaco Bonefish a

BONEFISHING ON ABACO: A CHALLENGE IS ACCEPTED

Here is my fly box. It is a qualified success, as is my fishing. The fly box is rather better organised than I am, though. Some of the flies in it are routinely ignored by others to whom I helpfully offer the box.  I’ve found the best plan is to stick with the silvery shrimpy patterns, especially the ones with pink heads. Then nobody gets upset. And from time to time I get lucky (see header image).

BF flies3a

Recently, a proper fisherman started to follow my blog, and I his. I immediately recognised one of the fishing lakes on his site, one where I have fished in the past. One thing led to another and I seem to have agreed to trial some of Mark’s expertly tied flies on the Abaco flats in March…

Mark’s Bonefish Patternsimage24

I am very keen on the principles of ‘Catch and Release’. So keen that I have developed my own specialist methods (designed for fishing with barbless hooks) using what might be termed ‘Early C&R’. These may include some or all of the following on any given day: 

  1.  ‘THE PHANTOM CATCH’ As the fish follows the fly, and the instant before it commits to a lunge for it, abruptly whisk the fly away from under its nose with a sharp reflex ‘trout-strike’. This will ensure that both the fish and your fly remain untroubled by actual contact. This is the most advanced form of Early C&R.
  2. ‘THE BIG MISSED TAKE’ As the fish takes your fly firmly in its mouth, become preoccupied by the fact that your left foot is planted firmly on a horrid tangle of line around your feet. You will feel the solid take, but instantly realise that your retrieve is hopelessly compromised. With some relief, you feel the line go slack as the fish shakes itself free…
  3. ‘THE REEL THING’ Hook the fish. Feel the weight on the end of the line. It’s heavy. Nice one! Turn in muted triumph to your boat partner to shout excitedly “Got One”. As you do so, allow the line somehow to snag round the rod handle and the reel simultaneously. Before you have even begun to figure how to sort this out, the fish will have released itself and be heading for the horizon.
  4. ‘THE STICKY SITUATION’ Hook the fish. Reel in confidently, keeping the line taut and the fish under your masterful control. Allow it to run if it wishes. Proceed with the same efficiency until you notice a single mangrove stem sticking out of the water 30 feet away. Using your skill, ensure that the fish suddenly has the chance to move to the other side of the stick, winding the leader or line (either will do) round it. Prepare for the ‘twang’ when the inevitable break occurs.  Your fish is away.
  5. ‘THE MANGROVE SWAMP’ Hook a fish. Play it competently until the moment your boat partner or guide gives you some word of encouragement or (worse) praise. Immediately, permit the fish to make a fast break for the nearest clump of mangroves even if it is over 100 feet away. The consequent entanglement round the myriad stems will be sure to lose you the fish and your fly. NOTE: all third party encouragement will diminish after this form of EC&R. Praise will not be repeated.

Mark has just made a challenge public on his website in a post called  All aboard for Abaco! “This little packet of flies is destined for the Bahamas… What stories will they conjure up in time? Rolling Harbour, Abaco… All will be revealed in time! Thanks in advance to RH – I will keep everyone posted in due course! Looking forward to some beautiful pictures of Bonefish…” The flies in question are shown below. It is expected that they will prove to be effective. The expectation is Mark’s. My own feeling is more one of hope. I hope he knows what he is doing. I hope I know what I am doing.*

Rolling Harbour, Abaco... All will be revealed in time!

*The plan is to ask my boat-partner and guide – anyone with access to a rod, really – to “have a go with one of these little guys”. They are far less likely to be as skilled as I am at Early C&R, and are therefore far more likely to boat a fish. Job done…

NEST PROTECTION: WILSON’S PLOVERS ON ABACO (2)


Wilson's Plover, Abaco 12

NEST PROTECTION: WILSON’S PLOVERS ON ABACO (2)

This is the second of three vaguely planned posts about these delightful shore birds. They aren’t rare but they are approachable and fun to watch. During the nesting and hatching season, there may even be some gorgeous chicks on a beach near you (a phrase I never thought I’d find myself using). PART ONE identified the typical male and female adults found on the Delphi beach almost any day. 

Nettie's Point, Abaco - Trucks & Skiffs

This post is about nest protection. Not the ingenious methods of  the birds themselves, that will come next time. This is a story of protection by humans. The photograph above shows Nettie’s Point, one of the launching points for bonefishing skiffs being taken out to the Marls, a vast area of sea, low sand banks and mangroves where the fish are found. You hope. The skiffs gain access to open sea via an artificial channel carved out of rock. The early morning trip along it is one of the most exciting part of a fisherman’s day, as he or she sets out with a clean score sheet, a rod and a box of flies. And a cooler box with some food and maybe a Kalik beer or three.

Nettie's Point, Abaco - the cut to the sea

This June, a pair of plovers decided to locate their nesting ‘scrape’ right in the middle of the cleared area where the trucks normally turn. This was by no means a wise home-planning decision, and they might well have found themselves being promptly relocated. Or (worst case scenario) ending up under a large Toyota. But not a bit of it. Instead, these small birds were looked after by the guides like this: Nettie's Point, Abaco - Plover's nest protection

A makeshift castle was built all round the nest to protect it from any inadvertent truck-related tragedies. Meanwhile the male plover stood guard outside the castle, amiably watching the human activities. Nettie's Point, Abaco - Male Wilson's Plover guards nest

I kept my distance but in fact he was quite unperturbed, perhaps sensing that we were not a threat. He still kept a beady eye on the proceedings, though.Nettie's Point, Abaco - male Wilson's Plover guards a nest

Meanwhile, what of the wooden enclosure itself? At first glance, there didn’t look much to report. However, if you look in the centre of the picture, you’ll see the female peeping out from the nest.Nettie's Point, Abaco - Nest protection 2

I very slowly moved nearer, prepared to stop if the male became agitated, or if the female shifted her position. Both seemed quite relaxed, so I took a couple of shots and walked away to leave the birds in peace. Then I went fishing.Nettie's Point, Abaco - Female Wilson's Plover on NestNettie's Point, Abaco - Mrs Wilson's Plover on the nest

As a postscript, Nettie’s Point is the location of a remarkable geographical phenomenon, possibly the result of the cutting of the channel. Along one part of the cut, for about 30 feet, the water level sinks alarming in the middle, while remaining normal at each side. Then it levels out again. This remarkable mid-stream aquatic depression is quite disconcerting to motor through on a skiff, though eventually one gets used to it. Nettie's Point, Abaco - channel water phenomenon(Note: not every fact in this post is 100% true.

IT’S ALL WHITE – IT’S A REDDISH EGRET ON ABACO


Reddish Egret (White Morph) Abaco 5

IT’S ALL WHITE – IT’S A REDDISH EGRET ON ABACO

Contrary to appearances from the header image and the one below, Reddish Egrets (Egretta rufescens) do not yet use cellphones to communicate. Nevertheless, the trick of having a good ear-scratch while standing in water on one leg is a good posey accomplishment.Reddish Egret (White Morph) Abaco 4

All these photos were taken while we were bonefishing from a skiff far out on the Marls in the mangroves. Ishi poled us closer so that boat-partner Tom – a real photographer – could get some shots. Meanwhile, I did my best with my little camera that I take out on the boat – the one that won’t matter too much when it slips from my hand or pocket into the drink. These things happen: I lost a good pair of Costas that a gust of wind unkindly whisked away when I took them off to change a fly.Reddish Egret (White Morph) Abaco 3Reddish Egret (White Morph) Abaco 2

This egret comes in two very different ‘colourways’. The classic version has a slatey-blue body and a reddish head and plumes. The white morph is pure white. The only similarities between the two are the two-tone bills with the black tip; and the blue-grey legs and feet.

True Reddish Egret, as you might expect it to lookReddish_Egret Wiki

The white morphReddish Egret (White Morph) Abaco 9

I’m not certain of the proportions of each type on Abaco, but I have certainly seen twice as many white ones as true reddish ones. There seem to be quite a few around – there are plenty of fish for them and dozens of square miles of human-free space in which to stalk them. However as with many (most?) of the bird species, there is a declining population for all the usual man-related reasons, and these fine birds have now had to be put on the IUCN ‘near-threatened’ list.220px-Status_iucn3.1_NT.svg

The bird kept an eye on us as we drifted closer, but was unperturbed. It continued to poke around in the mud, and occasionally it moved delicately but quite quickly to a different patch.Reddish Egret (White Morph) Abaco 8 Reddish Egret (White Morph) Abaco 7 Reddish Egret (White Morph) Abaco 6

We watched the bird for about 10 minutes. Then we returned to what we were really there for – Tom to catch bones with practised skill, and me to wave the rod incompetently around until some passing fish took pity on me and grabbed my fly, knowing it would soon be released once all the fuss was over…Reddish Egret (White Morph) Abaco 1

WILLET OR WON’T IT… GET CLOSE TO YOU?


WILLET OR WON’T IT… GET CLOSE TO YOU?

Willets (Tringa semipalmata) are large sandpipers, familiar as shore birds, foragers on sand bars and mudflats, or out in the mangrove swamps. Some might describe them as quite solid and plain to look at. Until they take flight, when their gorgeous wing patterns are revealed.

willet ©Greg Page @ Cornell Lab

Willets are ground-nesting birds, often breeding in colonies. They use their stout bills to forage on mudflats or in shallow water for insects, crustaceans, marine worms and occasionally plant-life. They tend to keep their distance, and in the past I have only managed this sort of unimpressive snapshot, not least because I normally only take a small basic camera out on the water in case it – or I – should fall in.Willet, Abaco Marls 1

However, we recently fished from the prow of a skiff parked on a sandy spit on the Abaco Marls, as bonefish came past on the tide. It was a productive hour for my boat-partner, though frankly less so for his boat-partner… As we fished, and to our surprise, a willet landed of the point of the spit to feed, and gradually worked its way towards us seemingly unconcerned by the skiff, by us or by the fish action. It started off about 30 feet away, and at close quarters it was far less drab and notably more elegant than expected.Willet, Abaco Marls 4

It foraged slowly towards us, keeping a beady inky-black eye on usWillet, Abaco Marls 2

At one time it came within a very few feet of us, then decided it had come close enough. We watched it stepping delicately away on its semi-palmated feet. The shot isn’t clear enough to show the slight webbing between the toes. However, you can clearly see the barred tail.Willet, Abaco Marls 5

In the c19 and early c20 there was a sharp population decline of these fine birds due to hunting. I’m not sure if it was for feathers, food or fun. All three, probably. Their population has recovered and their IUCN status is currently ‘Least Concern’, but like so many similar species they remain at risk, especially through continued habitat loss.

BABY BONEFISH, CASUARINA, ABACO HIDING IN PLAIN SIGHT…


Casuarina Bay (to south)

BABY BONEFISH, CASUARINA, ABACO: HIDING IN PLAIN SIGHT…

Bonefish are difficult to see in the water at the best of times. Shining silver out of water, but pale grey shadows underwater. Fishing under cloud cover and / or (especially ‘and’) when there’s a ripple on the water can be atritional. Sight-casting becomes impossible, and the best recourse is to locate the cloudy patches of water that show where the fish are feeding on the bottom. Chucking the fly into – or beyond – one of these and stripping back may be the only way to get a fish in such adverse conditions. What’s needed is clear sky, sunlight, good polaroids, patience, and keen eyes to scan the water for dark shadows moving across the sand… Or, in my case, simply waiting for the guide to hiss “Hey! Rolling Harbour. Three fish, 40 feet, 10 o’clock moving right, see them? Go now!”. By then, there’s a 50 / 50 chance I may have located them and got my act together enough to (try to) cast at them…

This picture of an adult fish, just caught on the Marls and released at once, shows how a bonefish can easily blend in with its underwater surroundings… but it can’t hide the dark shadow it casts.Adult Bonefish, The Marls, Abaco Bahamas

Two days later we went to Casuarina with friends who wanted a day’s wading on the extensive flats there. This photo shows a juvenile fish close to the beach there, on a glorious sunny day with a light breeze (the header picture [double-click] was taken the same day – low water over pale sand as far as the eye can see). I’d never have noticed this little fish, had I not seen the dark shadow it cast on the sand, magnified by the distorting effect of the ripples.

Without the distortion from surface ripples, the bonefish shape can be clearly seen. It’s hard to imagine that by the time this little fish has reached a weight of 2 lbs, he will be capable of stripping your line down to the backing in seconds… or could he?

No, not, in fact. This fish, with its deeply forked ‘bonefish’ tail, is in fact a YELLOWFIN MOJARRA also known as shad. As Zach Zuckerman of the CAPE ELEUTHERA INSTITUTE writes in kindly emphasising that the fish above is not a bonefish, “the yellowfin mojarra… is related to the mottled mojarra mentioned in Chris Haak’s text (see below). Yellowfin mojarra and bones share the same habitats, and mojarra also feed off of benthic invertebrates”. Which brings me to some interesting recent findings by the CAPE ELEUTHERA INSTITUTE in conjunction with thBONEFISH & TARPON TRUST. We saw a single small fish. It looked like a bonefish (though I guess the yellow fin markings suggested otherwise). It was in fact a similar-looking species. Where are all the young bones? The babies? How do they protect themselves from the many predators of juvenile fish?

EVER WONDER WHY YOU DON’T SEE SCHOOLS OF TINY BONEFISH ON THE FLATS?

Article ref: blog.ceibahamas.org

“Since May 2011, Christopher Haak, a PhD student (and avid fisherman) at the University of Massachusetts, Amherst, along with other scientists, has been trying to solve the mystery of where juvenile bonefish live, from settlement through the time they join adult populations on the flats.  Exhaustive efforts to locate juveniles along the densely-developed coastlines of Florida were met with little success, leading researchers to the comparatively pristine shorelines of The Bahamas to continue their search.

For the past one-and-a-half years, they have scoured the coastlines of South Eleuthera, conducting 1000+ seine hauls, encompassing a broad range of coastal habitats. This project is funded by Bonefish & Tarpon Trust and based out of CEI.   These efforts (with the help of South-Eleutherans; thanks Denny and Kelsey Rankin!) have succeeded in locating over 800 juvenile bonefish as small as one inch in length, and have revealed some intriguing trends.  For example, contrary to what might be expected, juvenile bonefish do not appear to frequent the mangrove creek systems or expansive tidal flats commonly used by adults, preferring instead to remain along shallow, sheltered shorelines near deeper basins or channels.”

Can you find the juvenile bonefish among the mojarra in the picture below?

“Perhaps the most remarkable finding to date is that nearly every bonefish collected was in the company of much greater numbers of like-sized mojarras (a common schooling baitfish known to Bahamians as shad).  These juvenile bonefish exhibited markings and coloration not apparent in adult bonefish, but very similar to the mojarras with which they were caught.  By blending in with considerably greater numbers of the model species, the mimics may be reducing their predation risk, and increasing their chances of survival.  In the case of bonefish, this hypothesis would also explain why juveniles are so rarely observed; they are well hidden within schools of mojarras!  From a conservation perspective, this suggests that bonefish populations may be dependent upon healthy mojarra populations, important information for resource managers.

This research is also producing valuable information about the diverse juvenile fish communities that inhabit Eleuthera’s shores.  Myriad seine hauls of the island’s beaches, bays, sounds, and creeks have catalogued juvenile fishes from a wide array of species, including other flats inhabitants like permit, reef fish such as parrotfish, jacks, and wrasses, and some very unusual demersal critters such as shortnose batfish.  The high densities and diversity of juvenile fishes revealed by this study serves to highlight the importance of these nearshore habitats to healthy adult fish populations of all kinds, underscoring the need to preserve and care for our coastlines.”
