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…

CONCH SHELLS & CONCHUPISCENCE ON ABACO

Most conchs encountered in daily life are lying peacefully on the beach; or are artfully displayed; or are found in conch heaps (often in the vicinity of restaurants) like the ones below at Sandy Point. Conchs at Sandy Point Abaco 2Conchs at Sandy Point Abaco 4

It’s easy to forget that these shells are more than just a garden adornment, or pretty containers for a ubiquitous Caribbean food. Under the sea, and not very far at that, are living creatures going about their daily lives.Conch ©Melinda Riger @G B ScubaConch ©Melinda Riger @ GB Scuba

And that includes reproducing. This sounds as if it might be a cumbersome process, but (like porcupines) they seem to manage. Here is a pair preparing to mate. The male behind is presumably about to… well never mind. I’ve never seen the process, so it’s a case of using imagination. Or just accepting that, whatever it is that they do, it works.

You’ll find some more about Conchs in a previous post HERE, including 12 Unputdownable Conch Facts, notes on conservation matters and… a photo of Honeychile Rider, arguably the most famous conch-carrier ever. Oh, she was fictional, you say? But I always though she… How very disappointing.

CONSERVATION PIECE: AN ABACO ECO-MISCELLANY

From time to time I post individual items on the CONSERVATION page. This comprises an assortment of articles, photos, videos and graphics with an eco-message relevant to Abaco and its waters. They accumulate gradually, and occasionally it is good to post a selection for consideration. What is the most frequently found item of detritus on a beach? Is it ok to eat striped bass? How many uses does a coconut have? How quickly does the invasive lionfish population spread? What is Fish Pharm? How many years does it take for an aluminium can to decompose? These and many other questions are answered below.

NOAA MARINE DEBRIS PROGRAM

Keepin’ the Sea Free of Debris!

ICC volunteers clean 10 million lbs of trash from our coasts
May 16, 2013 by NOAA Marine Debris Program

By: Dianna Parker

One rubber chicken, 117 mattresses, 4,159 candles, and 689,274 utensils. What do all of these things have in common?

They’re all marine debris collected last September at the Ocean Conservancy’s 2012 International Coastal Cleanup®, sponsored in part by the NOAA Marine Debris Program.The numbers are in: more than 550,000 volunteers came together to collect 10 million pounds of marine debris.  In the United States, volunteers found enough bottles that, when stacked end to end, equal the height of 1,000 Empire State Buildings. That’s a lot of trash on our beaches and in our waterways!This litter is threatening our marine environment, economy, and health, and the problem will only get worse unless we change the way we consume and dispose of products. There are solutions, and we can prevent litter from ending up in the ocean.So here’s a challenge: the next time you use a throw-away item: a bag, bottle, or utensil, answer the question, “Where it’s going?” How will you keep your items from becoming litter in our oceans, rivers, and streams? Head to Ocean Conservancy’s data release page for some neat infographics on last year’s trash haul. Here are the top 10 types volunteers found this year

The debate about the seemingly unstoppable spread of the invasive lionfish species is well known. There are some who argue strongly that lionfish have their uses, and not merely as a food source. To see ongoing lionfish research by the organisation REEF click HERE To supplement the static projection graphic for lionfish spread (below), here is an active graphic that vividly shows how the species (love them or hate them) has expanded exponentially in numbers and range over a very short period

IUCN CUBAN PARROT RED LIST RANGE MAP FOR AT RISK SPECIES
I have annotated this IUCN map of the Cuban Parrot population range. It’s worth noting that the Bahamian subspecies is now found only as a breeding population on Abaco and Inagua, being defunct on all other islands since the mid-c20. Of these populations, only the Abaco parrot breeds underground, a unique feature among the whole species.
I am puzzled by the suggestion of an ‘extant (resident)’ population on the Bimini Is. That would suggest that they breed there. I don’t know the date of the map, but I have checked with the Avibase bird database, and the Cuban parrot is indeed included in the list of Bimini birds. I’ve put a query on the map because I don’t know what the position is in 2012.

FRIENDS OF THE ENVIRONMENT (ABACO)
This conservation organisation has recently completely redesigned its website (click logo above), and presents comprehensive and easily navigated information about a myriad aspects of conservation on Abaco and its fragile ecology. The fragility is mostly directly or indirectly caused by mankind (a broad statement, I know, but it’s an arguable stance), so it’s worth checking out the measures that are being undertaken to preserve the natural resources of the island and its cays. Below is a post about one feature highlighted on the FotE site that I am particularly interested in. Overall all the new website is definitely one for any Abaconian (or, like me, regular visitor) to study. If you want to contribute your support (either generally or to a specific cause) go to the FotE website (click logo) or visit the Rolling Harbour wildlife charity page HERE

THE EFFECT OF RISING SEA LEVELS IN THE CARIBBEAN

This map has been posted by the SCSCB, with the very interesting and definitely worrying text “The map shows projected impacts of a 2 meter sea level rise in the Caribbean. The orange is the impact of 2 meters, while the yellow is the 25 meter line. The last time the ice caps melted the sea rose between 18 and 25 meters. The most conservative estimates indicate a 1-meter rise by the end of the century (concurrent with a 2 degree C rise in temperature). From the position of planning, I am curious about the estimates being used by Caribbean resource managers in their long-range planning. For example, what percentage of Caribbean seabirds nest below 2 meters…”

CONCH CONSERVATION

The supply of conchs is not infinite. Overfish them, take them before maturity  or pollute their habitat and this valuable marine resource depletes – and conchs, as with so many marine species, will become threatened. Fortunately there is a Bahamas-wide conservation organisation with a website packed with interest.  COMMUNITY CONCH is “a nonprofit organization that aims to protect queen conchs in the Bahamas, a species of mollusk threatened by aggressive over-fishing. We promote sustainable harvest of queen conch through research, education and community-based conservation”

BAHAMAS NATIONAL TRUST PRESS RELEASE JUNE 2012

ABACO PARROT POPULATION ON THE RISE

The Bahamas National Trust  in conjunction with Dr. Frank Riviera and Caroline Stahala recently conducted an intensive survey of the Bahama Parrot on Abaco Population surveys conducted in 2002 resulted in estimates of the Abaco parrot population of about 2,500 parrots with similar values in the following years. This year Dr. Frank Rivera and Caroline Stahala, who took part in the initial surveys, helped by  BNT wardens and volunteers, conducted a 10 year follow up survey to determine the change in the Abaco parrot population since management began. The results indicate that the Abaco parrot population has increased since the BNT’s management efforts were implemented with a new estimate of just over 4,000 parrots on Abaco. The BNT has been concerned about the Bahama Parrot Population since the 1980’s. Studies indicated that the major threat to the parrots were feral cats who cause serious problems to the parrots during the nesting season by entering the underground nesting cavities and killing the breeding adults and chicks. The BNT implemented an intensive predator control effort in 2009 throughout the parrot nesting area culminating in the hiring of Marcus Davis as Deputy Park whose primary responsibility is to oversee the predator control program. During the breeding seasons the BNT has seen a decrease in the number of breeding parrots killed and nest success increase. The question, though, remained whether this effort would translate into an increase in the Abaco parrot population size. Survey results indicated that predator control has led to an increase in nest success.  In addition, the Abaco parrots have weathered several hurricanes (Frances, Jean and Irene) over the last 10 years and still appear to show  a population increase. Hopefully with continued management efforts a healthy and viable  endemic parrot population on Abaco will continue to thrive. According to David Knowles, BNT Director of Parks “This gives us hope that with continued management efforts we can continue to have a healthy and viable endemic parrot population on Abaco.”

BAHAMAS CONCH QUEST – GASTROPODS, SHELLS & CONSERVATION


BAHAMAS CONCH QUEST – GASTROPODS, SHELLS & CONSERVATION

Conchs are among the most familiar of all shells. On Abaco they are everywhere: in the sea, on the beach, used ornamentally in gardens, piled up wherever conch is on the menu… (basically, anywhere serving food)

Conchs have other uses besides being a staple food. They provide sought-after pink pearls.  Only about 1 conch in 10,000 has a pearl, so bear in mind that if you miss one during your search, you may have another 10,000 to wade through… Conchs can produce music, of a sort (such as when used enthusiastically by the famous ‘conch-blower’ home-team supporter during cricket Test Matches in the West Indies). They are undeniably decorative on a porch or on a shelf.

Conchs have featured in literature and film. In William Golding’s Lord of the Flies the conch represents power and order. A conch is blown to call meetings of the marooned boys. Its power is symbolised by the rule that you have to be holding it to speak at the meeting (an idea that many – all? – Parliaments could benefit from…)

Ian Fleming mentions conchs in several of the Bond books, all such references being totally eclipsed by the memory of the appearance, in the film Dr No, of Honeychile Rider emerging from the sea, conch in hand. Oh, I see. That’s just men is it? Or (good grief) just me? Anyway, may we all agree amicably that Ursula Andress was a most decorative conch carrier?

In many past posts I have listed ’10 Essential Facts’ about the topic discussed. In that spirit I have borrowed and slightly edited CC’s conch facts; and added a CC video of a conch’s stately ‘full speed ahead’ progress. NB No zoom… 

12 CONCH FACTS

  • The queen conch is a large edible sea snail native to the coasts of the Caribbean, the Florida Keys, the Bahamas, and Bermuda. Conchs are herbivores – they eat algae and other tiny marine plants
  • Main predators include nurse sharks, loggerhead turtles, other snail species, blue crabs, eagle rays, spiny lobsters, and other crustaceans
  • Mating aggregations may contain hundreds or even thousands of individual male and female conchs
  • Female conchs lay hundreds of thousands of tiny eggs in a sandy egg mass. The larvae emerge after 5 days and may drift on ocean currents for a month before settling in suitable habitat on the sea floor
  • In their first year conchs live under the sand during the day & come out to feed on the surface at night
  • A queen conch may take 5 years to reach maturity and can reproduce
  • They live an average of 7 years, but are known to live as long as 20 – 30 years
  • Conchs produce natural pearls that come in a range of hues, including white, brown, orange & pink
  • The conch is listed by CITES as a species which may become threatened with extinction if trade is not tightly controlled
  • It is now illegal to take queen conchs in the state of Florida due to severe overfishing
  • 80% of legal internationally traded conch is consumed in the United States. The smuggling of conch meat into the U.S. is a significant challenge to conch management in The Bahamas
  • Queen conch are vulnerable to overfishing because they are (1) relatively slow to grow (2) late to mature (3) aggregate to mate (4) easily harvested in shallow waters
