THE CONCH QUEST OF ABACO…

THE CONCH QUEST OF ABACO…

Conchs are gastropods. They are food. They are decoration (anyway, the shells are). For some, they are a living. And on Abaco they are everywhere – alive in the waters, and as shells scattered on  beaches or piled up outside restaurants. So the quest for conch is an easy one. There are fears of overfishing, however, and an active organisation The Bahamas National Conchservation Campaign exists to protect them. Another similar Bahamas organisation is Community Conch.conchs-at-sandy-point-1 We found a nice half-buried conch shell at Sandy Point. It was full of sand grains and tiny shells – mini gastropods and bivalves - that took some time to wash out of the spiralling internal structure. Here are some studies of the shell. IMG_2438IMG_2442IMG_2444IMG_2445IMG_2448IMG_5279IMG_5278 The damage to the shell above is the place where it has been bashed in to enable removal of the occupant. In order to do so, it is necessary to break the strong vacuum that would prevent extraction if you tried by the conventional route. Effectively the conch anchors itself to its shell and must be cut out. The best way to make the hole is with the spiral tip of another conch. This breaks the suction and enables you to prise out the occupant…

“REEF ENCOUNTER”: TEN CHEERFUL BAHAMAS REEF FISH

LAURA JESSON “Do you know, I believe we should all behave quite differently if we lived in a warm, sunny climate all the time. We shouldn’t be so withdrawn and shy and difficult…” (Brief Encounter 1945) 

The quote is there both because it is particularly apposite for any withdrawn etc Brit with a toehold in Abaco, and because it explains or excuses the somewhat clumsy title pun… March has been dominated by (a) a trip to Abaco and (b) publication of “The Birds of Abaco”. Time for some cheerful finny  fotos to end the month with, courtesy of diving belle Melinda Riger of Grand Bahama Scuba and her top-class camera work.

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.

Then they slowly drifted away across the sand…Stingrays Abaco Marls 7

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.

Stranding Response to Support Conservation of Marine Mammals in the Bahamas 

Increasing capacity and available funds to respond rapidly to strandings in The Bahamas will increase our ability to determine cause of death and/or successful rehabilitation of marine mammals. At the first stranding workshop held in the Bahamas in 2008, the Honourable Lawrence Cartwright, Minister of Agriculture and Marine Resources officially opened the workshop stating “I believe the establishment of a Marine Mammal Stranding Network in The Bahamas will serve to promote the conservation of marine mammal species and their habitat by improving the rescue and humane care of stranded marine mammals, advancing stranding science, and increasing public awareness through education.” This funding will provide the resources to train veterinarians on how to work with stranded marine mammals as well as provide the resources to respond to strandings.

Field Research & Outreach to Support Conservation of Bahamas Marine Mammals

Cetaceans are long-lived, highly specialised animals with delayed reproduction and low fecundity, which makes them incapable of rapid adaptation and thus particularly vulnerable to anthropogenic impacts. BMMRO has compiled an unprecedented long-term dataset for the region, which has become increasingly valuable to inform about the baseline ecology of some odontocete species. This research will ensure that this important work continues to fill key gaps in our knowledge about the ecology of marine mammals. Additionally, we will increase awareness and build capacity amongst Bahamians, both of which will contribute to local conservation needs.

JANUARY SIGHTINGS

For Abaco, the excitement is the sperm whale seen just off the Rocky Point area. More generally for the northern Bahamas, in addition to the manatee Georgie (former temporary resident of Abaco) and others, there was a manatee reported on Eleuthera. It looks as though these gently creatures continue to find the area to their liking.

SPOTTED & SMOOTH TRUNKFISH: BAHAMAS REEF FISH (16)

THE SPOTTED TRUNKFISH is a reef fish distinctive for its dark spots on a silvery-white background. It’s very wrong of me to comment, I know, but arguably its appearance is amusing. It probably feels the same about divers with all their gear…Trunkfish ©Melinda Riger @GBS copyTrunkfish © Melinda Riger @ Grand Bahama Scuba copy 2

However the trunkfish deserves to be treated with due respect. When touched, they secrete a colourless toxin from glands on their skin. The toxin is only dangerous when ingested, so divers are unlikely to be harmed by the it.  Predators however are at risk, and creatures as large as nurse sharks are known to have died as a result of eating a trunkfish.

THE SMOOTH TRUNKFISH is almost a negative of the spotted trunkfish, with white spots on a dark background rather than vice versa. Adults develop hexagonal patterning on their sides. They also secrete toxins and are best left untouched. Their ability to pucker up is impressive…Trunkfish (Wiki)Trunkfish © Melinda Riger @ Grand Bahama ScubaLactophrys triqueter (Smooth Trunkfish) juvenile Wiki

MARINE DEBRIS? NO THANKS! 10 FACTS FROM NOAA


Ten Things You Should Know About Marine Debris

monksealMonkseal being rescued from marine debris

Entangled-harbor-seal NOAA Marine Debris
Our waterways are littered with stuff that doesn’t belong in them. Plastic bags, cigarette butts, fishing nets, sunken vessels, glass bottles, abandoned crab traps…the list is endless. Some of this marine debris comes from human activity at sea, and some of it makes its way into our waterways from land.
While we know that marine debris is bad for the environment, harms wildlife, and threatens human health and navigation, there is much we don’t know. How much marine debris is in our environment? How long does it last? How harmful is it to natural resources or human health and safety? How long does it take to break down in the water? The NOAA Marine Debris Program is finding answers to these questions.

1. It doesn’t stay put

While a lot of debris sinks, much also floats. Once this marine debris enters the ocean, it moves via oceanic currents and atmospheric winds. Factors that affect currents and winds (for example, El Niño and seasonal changes) also affect the movement of marine debris in the ocean. Debris is often carried far from its origin, which makes it difficult to determine exactly where an item came from.

2. It comes in many forms

Marine debris comes in many forms, ranging from small plastic cigarette butts to 4,000-pound derelict fishing nets. Plastic bags, glass, metal, Styrofoam, tires, derelict fishing gear, and abandoned vessels are all examples of debris that often ends up in our waterways.img_0510_ss-1

3. It’s your problem, too

Marine debris is a problem for all of us. It affects everything from the environment to the economy; from fishing and navigation to human health and safety; from the tiniest coral polyps to giant blue whales.

4. NOAA is fighting this problem

The NOAA Marine Debris Program works in the U.S. and around the world to research, reduce, and prevent debris in our oceans and coastal waterways. Much of this work is done in partnership with other agencies, non-governmental organizations, academia, industry, and private businesses.The Marine Debris Research, Prevention, and Reduction Act, signed into law in 2006, formally created the Marine Debris Program. The Act directs NOAA to map, identify, measure impacts of, remove, and prevent marine debris.

img_0327

5. Some debris is being turned into energy

Abandoned and lost fishing gear is a big problem. It entangles and kills marine life and is a hazard to navigation. Based on a model program in Hawaii, the Fishing for Energy program was formed in 2008 to tackle this problem with creative new ideas. The program is a partnership between NOAA, Covanta Energy Corporation, National Fish and Wildlife Foundation, and Schnitzer Steel.This program offers the fishing community a no-cost way to dispose of old or derelict fishing gear. Once removed from the environment, the gear is transported to the nearest Covanta Energy-from-Waste facility. About one ton of derelict nets creates enough electricity to power one home for 25 days!

6. Marine debris can hurt or kill animals

Marine debris may be mistaken by some animals for food or eaten accidently. Often, larger items like nets, fishing line, and abandoned crab pots snare or trap animals. Entanglement can lead to injury, illness, suffocation, starvation, and even death. NOAA is working with many partners to tackle this problem by reducing and preventing marine debris in our oceans and waterways.

7. There’s a lot to learn about this problem

We know that marine debris is a big problem, but there’s much we need to learn. NOAA funds projects across the country and works with scientists and experts around the globe to better understand how marine debris moves, where it comes from, and how it affects the environment. This knowledge will help us find better ways to tackle the problem.

8. You can help us get the word out!

The NOAA Marine Debris Program offers a heap of creative products to get the word out about marine debris. Looking for brochures, posters, fact sheets, or guidebooks? We’ve got those. Like videos? We’ve got those, too. We even have a blog! You’ll find it all online.

9. This is a global problem.

Marine debris is a global problem that requires global solutions. NOAA experts work with scientists and organizations around the world to share lessons learned, discover what programs work best, and map out future strategies to fight this problem.

img_04761

10. Small steps lead to big results

Fighting the marine debris problem begins at home.

  • - Try to cut back on the amount of trash you produce.
  • - Opt for reusable items instead of single-use products.
  • - Recycle as much of your trash as you can.
  • - Join local efforts to pick up trash.
  • - Keep streets, sidewalks, parking lots, and storm drains free of trash—they can empty into our oceans and waterways.

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…

THE TANG OF THE BAHAMIAN SEAS… BLUE TANG, IN FACT


Blue Tang School ©Melinda Riger @ G B Scuba copy

THE TANG OF THE BAHAMIAN SEAS… BLUE TANG, IN FACT 

The Blue Tang Acanthurus coeruleus is a species of Atlantic surgeonfish mostly found on coral reefs. They are known as surgeonfish because they can slice you with their sharp, spiny caudal fins. Adults are blue, ranging from a deep blue or even purplish to much paler blue.fish28Blue Tang ©Melinda Riga @ G B ScubaBlue Tang ©Melinda Riger @ GB Scuba

Surprisingly, as juveniles, Blue Tang are bright yellow.Blue Tang (juv) © Melinda Riger @ Grand Bahama Scuba Blue Tang (juv yellow form) © Melinda Riger @ G B Scuba

As they grow, they become blue, with the tail being the last part to lose the yellow.Blue Tang (Juvenile) ©Melinda Riger@ G B Scuba Blue Tang (juv, changing colour) © Melinda Riger @ G B Scuba

Blue Tang are herbivores, cruising constantly round reefs feeding on algae. They also act as cleaners of other fish species, removing parasites. They themselves may be cleaned by gobies by visiting so-called ‘cleaning stations’. These piscine beauty parlours have a medicinal purpose as well, since cleaning helps to cure minor wounds.

These fish often move around reefs in large schools, as shown in the header image. Apart from having some value as an aquarium fish, they are not generally of use to humans. Their spiny caudal fins can cause a nasty wound. They have an unpleasant smell. Their flesh supposedly contains toxins, and they carrying a risk of the disease CIGUATERA. I can’t even find a recipe for them online – now, that is a bad sign, there are some people who will try anything. I guess best to boil them for an hour or two, drain the water, allow to cool, and throw away the fish.

FUN FACT In the Disney/Pixar film Finding Nemo, the character Dory (voiced by Ellen DeGeneres) is a blue tang.

BLUE TANG: THE MOVIE [RE-RELEASE]

“RECIPE Take one incompetent swimmer who hasn’t snorkelled in, oh, nearly 40 years. Place him over a coral reef for his first time ever. Add a small underwater camera totally alien to him. Immerse for 30 minutes in warm briny water. Lessons have been learnt for next time. Mainly, don’t keep waving the camera about; let the fish move round you rather than vice versa; and most important of all, remember to keep breathing or else…

Here is BLUE TANG: THE MOVIE (music by Adrian Legg), 45 secs of advanced camera-shake with some beautiful fish more or less in shot for most of the time. If you are prone to sea-sickness, do not enlarge the video. If you are allergic to poor photography… well, thanks for visiting.”

WTF? (WHAT’S THAT FISH?) REMORAS: WEIRD SUCKERS


File:Nurse shark with remoras.jpg

WTF? (WHAT’S THAT FISH?) REMORAS: WEIRD SUCKERS

WHAT ON EARTH ARE REMORAS?

Remoras (Echeneidae), also known as Sharksuckers, Whalesuckers or Suckerfishes, are  ray-finned fish that grow up to 3 feet long. Remora ©Melinda Riger @ G B Scuba copy

You may have noticed them in pictures of sharks and wondered briefly why they hang out with such dangerous creatures. There is filmed evidence that remoras do occasionally get eaten by their hosts…383586_510314062323321_1002533913_n

WHAT DO THEY DO?

Remoras have remarkable dorsal fins that form a sucker-like organ with a ribbed structure. It looks a bit like the sole of a trainer or beach shoe.Remora (head( ©Melinda Riger @ G B ScubaThis bizarre organ can open and close to create or release suction, enabling it can latch onto larger marine creatures. The remora can increase suction by sliding backward, or it can release itself by swimming forward – the ‘slats’ are smooth in one direction, and rough the other way. They have been known to attach themselves to boats. And scuba divers. Even with hairy legs…

WHAT KIND OF CREATURES DO THEY GET ATTACHED TO?

Remoras  associate with specific host species. They commonly attach themselves to sharks, manta rays, whales, turtles, and manatees / dugongs. Smaller remoras may latch onto fish such as tuna and swordfish, and some travel in the mouths or gills of large manta rays, ocean sunfish, swordfish, and sailfish.File:Manta-ray australia.jpgFile:Sea turtle and remora.JPGFile:Mother and baby sperm whale.jpg

WHY WOULD THEY WANT TO DO THAT?

The relationship between a remora and its host is known as  Commensalismspecifically ‘Phoresy‘. The host to which it attaches for transport gains nothing from the relationship, but also loses little. The remora benefits by using the host as transport and protection, and also feeds on morsels dropped by the host. Controversy surrounds whether a remora’s diet is primarily leftover fragments, or the feces of the host. Maybe it’s a healthy  mix of both.

Remora ©Melinda Riger @GBS

WHERE CAN I FIND ONE?

Remoras are found in tropical, sub-tropical and temperate waters, including the mediterranean. You will definitely find them in the Bahamas. Melinda’s photos were all taken in the waters south of Grand Bahama.

ARE THEY USEFUL TO MANKIND IN ANY WAY?

Yes, but not in a good way, some may think. Some cultures use remoras to catch turtles. A cord or rope is fastened to the remora’s tail, and when a turtle is sighted, the fish is released from the boat; it usually heads directly for the turtle and fastens itself to the turtle’s shell, and then both remora and turtle are hauled in. Smaller turtles can be pulled completely into the boat by this method, while larger ones are hauled within harpooning range. This practice has been reported throughout the Indian Ocean, especially from eastern Africa near Zanzibar and Mozambique,  from northern Australia, Japan and even the Americas.

Remora ©Melinda Riger @ G B Scuba

Because of the shape of the jaws, appearance of the sucker, and coloration of the remora, it sometimes appears to be swimming upside down (see above). This probably led to an older name reversus, although this might also derive from the fact that the remora frequently attaches itself to the tops of manta rays or other fish, so that the remora is upside down while attached.

THANKS FOR THAT. BUT WHERE CAN I GET MORE INFO ON THESE SUCKERS?

RIGHT HERE – AN EXCELLENT VIDEO WITH PLENTY OF LIVE REMORA ACTION

OH! FINAL QUESTION. ARE REMORAS EDIBLE?

I though someone might ask that, so I’ve checked it out. Here is the best recipe I have found, expanded slightly from a blokey Australian chat thread:

Recipe for cooking Remora

  • put a 12 ltr pot on to boil
  • when the pot is bubbling violently, add 2 whole remora, 2 garden rocks, 1 carrot & a large turnip
  • add grandfather’s boots to taste, and turn heat down after 3 hours
  • simmer for a further 6 hours
  • turn off heat and drain carefully
  • remove and discard remora, and serve the rest on a bed of tin tacks

“Oh, that this too too solid flesh would melt, thaw and…” Ah! Sorry. I’m soliloquising again. Must be Thursday. And the merest mention of Hamlet is enough to set anyone off. But I speak not of noble yet gloomy Danes of Elsinore and of discernibly introspective aspect. These ones are pretty reef fish of the Caribbean seas, mainly in the Bahamas and along the Florida coast. There are a number of different types of hamlet, of which the 4 featured below in Melinda’s amazing underwater images were were encountered in one dive.

Hamlets have outstandingly interesting reproductive skills, being ‘synchronous hermaphrodites’. They have the unusual benefit of having both male and female sexual organs as adults, permitting imaginative combinations of pairings (though not including self-fertilization). When they find a mate, “the pair takes turns between which one acts as the male and which acts as the female through multiple matings, usually over the course of several nights”. I don’t dare check whether there are websites that cater for this sort of energetic coupling. The wonder is that Hamlets preferentially mate with individuals of their same colour pattern, and that they are not more wanton with their attentions and sexual flexibility.

OPTIONAL CULTURAL, HISTORICAL & MUSICAL DIVERSION INSPIRED BY HAMLET

The other notable Hamlet is, of course, the mild cigar equated in the famed commercials with happiness, accompanied by an excerpt from a jazzy version of Bach’s ‘Air on the G String’. Here is one of the best – and possibly the only advert to my knowledge to feature not one, but two excellent Sir Walter Raleigh jokes.

Bach’s well-known descending chord sequence of was of course shamelessly ripped off by ingeniously adapted by Procol Harum for ‘A Whiter Shade of Pale’, their first single in 1967. Relive the Summer of Love right here and now. Is this the music that might even put those versatile hamlets in the mood…


Any fret-tweakers might like to see the sheet music of the Air for guitar – you could even play it on air guitar – which is relatively easy, being in C major.Air on a G String - J S Bach - Guitar Tab JPGCredits: All fish pics Melinda Riger of Grand Bahama Scuba, except wiki-header; open-source online material; my mp3, dammit – I can’t get the wretched tune out of my mind…

PHILATELY WILL GET YOU… NICE BAHAMAS WILDLIFE STAMPS

WILDLIFE STAMPS OF THE BAHAMAS

with guest expert PHIL LATTERLY

The Bahamas ‘does’ extremely nice stamps, in particular ones featuring the rich and varied wildlife of the islands. The islands spread from the subtropical climates of the north, on a level with Florida, to the near-tropical islands of the south. This ensures plenty of scope for designing pretty sticky bits of paper to stick onto other bits of paper. One of the small pleasures in life, near-lost to the tyranny of the email…

The sets of wildlife stamps are issued by the Bahamas Post Office. I’ll add to this collection piecemeal (including some from my own modest collection). The very latest commemorative issue heads the display.

PARROT POST

Found mainly on Abaco (the resident underground nesting variety) and Inagua (conventional nesters), where they breed. Small groups are now found elsewhere, e.g. Nassau, where there is a local monitoring programme, but I’m not sure that there is evidence of breeding there. Any info welcome… One (of several) lavishly illustrated parrot posts HERE

OTHER BIRD SPECIES

Bahamas Wildlife Stamp Osprey

The KIRTLAND’S WARBLER is one of the rarest birds of the Bahamas, a winter resident that breeds only in a small area of Michigan. The entire population is numbers only a few thousand birds. The number of sightings annually on Abaco is very small – fewer than a dozen, and in some years none at all. Increasing knowledge about their favourite haunts is now improving the recording rate. I know of two seen this year, on the same day… a birder’s lifetime achievement.

One of the earliest posts in the Bahamas Reef Fish series was about Queen Angelfish Holacanthus ciliaris, and you can see it HERE. I make no apology for returning with some more recent photos from Melinda Riger – these fish deserve plenty of attention for their wonderful bright presence that stands out even amongst the colourful corals of the reef.

This first image is remarkable for its clarity and composition. What, I wonder, is the fish saying to Melinda as she presses the camera button? All caption suggestions welcome…Queen Angelfish © Melinda Riger @ G B Scuba

We are back in the realm of ‘animal, vegetable or mineral?’. Dive down a few feet – inches, even – to the reef, and… is this thing waving about here a plant or a creature? And is that colourful lump over there a bit of inanimate rock or a living thing?

4. GOLDEN ZOANTHIDS Coral forms living on a Green Rope Sponge. Some zoanthids contain a deadly poisin called palytoxin, which may do unspeakable things to your heart. Like stop it. Luckily, none so unpleasant live in the Bahamas (or so the Bahamian Tourist Board would no doubt wish me to make clear).

3 MONTHS ON ABACO WITH THE BMMRO: AN INTERN’S STORY

3 MONTHS ON ABACO WITH THE BMMRO: AN INTERN’S STORY

My name is Jack Lucas and I am Marine Biology Student at Plymouth University in the UK. I came to the Bahamas Marine Mammal Research Organisation on Abaco in July 2013 for a 3 month internship, which has been an amazing experience from start to finish. Heres a summary of my summer spent at BMMRO.

Sperm Whale Fluking

I arrived at the start of July and was fortunate enough with my timing to be part of an assembled crew of scientists from all over the world coming together to start work on what was to be this summers main project; collecting faecal samples from Blainville’s beaked whales to assess stress hormones produced. This team included Dr Roz Rolland and Dr Scott Kraus from New England Aquarium, who are collaborating with BMMRO for the work, and the samples will be analysed back at their lab in the US. Also along for the ride was Roxy Corbett; a whale observer and field researcher from the US, and Dr Stephanie King; a acoustician from the Sea Mammal Research Unit in Scotland. The first day after arriving it was straight out on the boat to search for these elusive creatures and the beginning of a crash course in how to collect and store the faecal samples when we found them. For the first week the work was a mix of boat work when the weather permitted and practicing poop collection using custom-made fine-mesh nets and coffee grounds (as close to the real thing as we were willing to try!), as well as clearing out BMMRO’s garage and, under the direction of foreman Scott, the construction from scratch of a lab to prepare samples for storage.

An example of the use of coffee grounds to practise whale poop-scoop technique269RH note: NOT Jack’s arms / snappy diving suit…

Unfortunately, despite days of poop collection practice and endless hours searching for the whales at sea, the original poop team never got a chance to employ these by now highly developed skills or to see the lab being used, as the weather was so windy we barely encountered the animals let alone spent long enough with them to collect any samples. 

Despite the lack of beaked whales, we did encounter loads of marine mammals in the first few weeks, from sperm whales to three different species of dolphin; including the little-seen and even less-studied rough-toothed dolphin.

Rough-toothed Dolphin

After discussion with Charlotte and Di about a possible project for me to complete during my stay, it was to be this species that I would focus on and in between the usual office jobs it was my task to sort through the photos from 20 rough toothed encounters in the Bahamas since 1995 and create a catalogue of individuals. This initial task consisted of careful inspection, comparison and sorting of what turned out to be over 5000 photos, into an organised catalogue of 167 separate and distinctive individuals. Despite the hours of endless staring at fins, it was very rewarding as there were 13 resighted individuals found (we were not necessarily expecting any!) which suggests long-term site fidelity and association of these animals, in addition to year round use of the Grand Bahama Canyon. Even more rewarding; the results of this work have recently been submitted for a poster display at an Odontocete workshop in New Zealand this December and I am also writing up the results in a formal scientific paper, with the hopeful goal of publishing a note in a peer-review journal. 

 Scott, Jack, Stephanie and Di in the new lab at Sandy Point

Around a month in I was lucky enough to be sent by Di and Charlotte to Great Harbour Cay on the nearby Berry Islands to work with the manatees there, in particular Georgie; a recently released juvenile whose status is being carefully monitored after her rehabilitation at Atlantis’ Dolphin Cay following health problems. The work here for a week under the guidance of Kendria; a Bahamian contracted by BMMRO to monitor the manatees on the Berry Islands, consisted of tracking Georgie using a satellite tag attached to a belt around her tail. Once located, we logged her position and made any notes on her health and behaviour aswell as the other manatees that were often found with her (there are currently 6 located on Great Harbour Cay). Two days in her tag was found unattached at a locals dock (it has a weak-link incase of entanglement) and we had to locate her using underwater hydrophones to detect her belt. Once found, I had the rare opportunity of entering the water with her in order to re-attach a new tag to her belt; it was amazing and one of the best encounters I have had with any animal! It is impossible not to love these amiable and gentle creatures, especially when you observe their infamous ‘hugs’ in person! 

Georgie the Manatee

For more about Georgie’s re-release in the Berry Is. after her earlier shenanigans on Abaco, see HERE

After returning from the Berry Islands (and incidentally missing the first two poop collections of the season made by Charlotte!) it was back to hunting for the elusive beaked whales around South Abaco. During my time I had the chance to work with several interns coming to BMMRO including local marine-enthusiasts Tristan and AJ, and Courtney Cox from Florida. Oscar Ward from the UK also joined the team as Charlotte left for Scotland to complete her PhD, and was on hand during the poop-collection and other little excursions. In wasn’t until the last month of my time here that we managed to get close enough to the whales for me to get in the water and be towed alongside in the hope of seeing one defecate. One amazing morning two whales surfaced right off the bow of the boat and what resulted was again, one of the most amazing moments; swimming just a couple of feet away from an animal only a handful of people in the world have seen underwater. After nearly two months with no samples, the two weeks that followed were a flurry of boat days, poop-collection and whale watching; with a total of 7 samples collecting from beaked whales (5 in one day!!) and another 3 from sperm whales. This was the best possible end to my time here and I finally got a chance to use the much-practiced poop collection techniques. The samples included a number of squid beaks, and in one very deep dive collection a mass of parasitic worms and a weird cephalopod-type animal! We also got a chance in the last few weeks to test-run a new addition to the fleet, that included a dive compressor.

Ready to collect some poop…

Finally my time in the Bahamas had to come to an end, and I had to return home. The last 3 months has flown by and has been one of the most enjoyable and most importantly educational periods of my life and I cannot thank Di and Charlotte enough for making it all possible. The day-to-day boat runs, office work, equipment maintenance and station chores has given me a good insight into all aspects of field research. It was my first taste of life as a marine mammal scientist, and it has made me even more determined to pursue a career in this field; a perfect stepping stone from which to move forward. In addition my work with BMMRO (and what must of been a brilliant reference from the girls!) made it possible to secure a highly competitive internship in the Farallon Islands this winter tagging elephant seals amongst other work! I cannot wait to continue working in this field and finish writing up the results of my project here, and hope I have the chance to come to Abaco again to work with these amazing people and animals!Sperm Whale supplier of poop BMMRO

BMMRO would like to thank Jack for all his help during the summer, and all our interns for their assistance! To our sponsors, Friends of the Environment, Disney Animal Programs and Environmental Initiatives and Rotary of Abaco, we thank you for your continued support.

TIGER GROUPER Mycteroperca tigris – BAHAMAS REEF FISH (12)


TIGER GROUPER Mycteroperca tigris – BAHAMAS REEF FISH (12)

Tiger Grouper ©Melinda Riger @ GB Scuba

The grouper family is a large one, and a number of varieties of the species inhabit Bahamas waters. Like most groupers, these are denizens of coral reefs. An adult grouper may grow to 3 ft long and weigh in the region of 10 lbs.

Groupers are effective predators, with strong gills that enable them to suck their prey into their large mouths from a short distance away. They will eat smaller fish, crustaceans, and even OCTOPUSES (click to discover the correct plural form for this creature).

Tiger Grouper 2Tiger Grouper copy

Many divers become familiar with the groupers of the reefs they explore, and some of the fish are given pet names. They are often distinguished from each other by distinctive markings or injury scars. More varieties of grouper will be on show soon; though it has to be said that this series will be no beauty parade… (see above and below for further details)
