Helping to Sustain a Way of Life in the Bahamas

New report and publication available for download!

We now have two new and interesting documents to share with you! Community Conch wrapped up reporting on our fifth conch survey season in the Jumento Cays and Ragged Islands, and we’ve added another publication of significant fishery management value. Click here to download the docs.

The first is the final report on the survey work we completed last summer in Jumento Cays and Ragged Islands. Given that we did find considerably healthier populations of conch in these southern Bahamian islands, it makes for a more uplifting read that our previous reports. Though we are glad to see the numbers are higher in these hard to fish areas, we still offers some precautionary management recommendations.

We have also recently had a paper published in the Journal of Shellfish Research on a study conducted by Dr. Stoner and our colleague Karl Mueller. Data was collected during the Exuma Cays expedition in 2011 to study the relationship between operculum dimensions and shell lip thickness. As we all know by now (right?!), lip thickness is an indicator of the age of a conch and the sexual maturity of the animal. As it turns out, checking the operculum might also be a good indicator too. The significance of this study lies in its potential usefulness to fishery managers. A major issue with enforcement of current fishery laws is the fact that most shells are discarded at sea and therefore the shells are never seen at landing docks. So, its impossible to tell whether the conch had a flared lip, much less what the lip thickness of the shell was. If fishers were required to land cleaned conchs with the operculum in tact, fishery officers would have an alternative way to determine if the animal was indeed legally harvested. Plus, fishers would not have to weigh their boats down with heavy shells which has been noted by some as a real hazard at sea. Now, quick! Find out what an operculum is!

 

 

 

Happy Thanksgiving!

Thanksgiving is not traditionally celebrated in The Bahamas, but we thought it would be a good opportunity to say thank you once again to all of the volunteers who help us out each summer. Enjoy this photo collage of volunteers that joined us in the Berry Islands, Andros, Exuma, Abaco, and down south in the Jumento Cays and Ragged Island. We could not possibly have counted and measured all of those conchs without you! Thank you!

Meet the R/Js team

In addition to the usual Community Conch team, we were joined by four volunteers this year. And we really couldn’t have chosen a better crew, because these folks were truly up for the challenge. In this post we’ll feature Erin Cash, a native of Nassau. Erin was great to have on board because not only was her master’s thesis focus on the queen conch (experience!), having just finished her thesis she was not afraid of data entry (bonus skill!), and was all around a fun person to have around (people person!). Despite a few bouts of sea sickness, Erin was also really excited to be towed behind a boat (or maybe not so much, but she did it anyway!). And she really loves conch, as you will see in her post…

Erin was especially skilled in measuring the length and lip thickness of conch shells in the smelly old conch middens we came across.

When the opportunity was first presented to me to help on the conch project I couldn’t be more excited. As a recent graduate whose thesis revolved around this hopping strombid, I leapt at the chance to work with it again. After two and a half weeks, a couple of peaceful run-ins with a few toothy friends and a new perspective on the necessity of sunblock, I felt that all hope was not lost; though I am “missing” a couple of unwanted pounds.
Every day that we went out something new was waiting to be discovered. Some information was scientifically minded- like the densities we found- and some of it was on the human level. When you’re at sea for weeks at a time it can get a little lonely. You worry that you may run out of conversations. I remember warning another volunteer in the airport about catching up too quickly; I was worried we’d run out of things to say. However, we were able to interact with new people who were old to the area at almost every stop. Learning their perspectives and at times having a dialog as to what can and should be done about environmental issues. As the resident city slicker, being from Nassau, I was able to learn new things about my own country that I never would have known. Evidently there is at least one flamingo in the Jumentos!

The best thing I learned was that it was not all for naught. While we have a way to go it was refreshing to see relatively healthy populations. It was enlightening to survey middens that weren’t pervaded with the shells of juveniles. It was humbling to see the beauty my country presents both with its self-contained cays and staggering painted sea. It was a little dicey being pulled on a tow rope behind a boat in some of those seas, but hey- we do it for science. We do it for the conch. We do it because really, who else will? We have to see. We have to learn. We have to have that information. We have to move forward. I did it because I had to. I’m glad that I did. I’m still thrown about that flamingo though…

Ragged Island and Jumento Cays surveys – check!

This year’s conch surveys took us to a remote location in the southern Bahamas, the Ragged Island and Jumento Cays (R/Js) chain. Ragged Island, just 60+ miles from Cuba lies at the southern end of the chain and is inhabited by a small, resourceful Bahamian community known as Duncan Town. The rest of the islands, cays, and rocks in this long archipelago, which stretch north in an arc over 100 miles long, are only home to the abundant wildlife above and below the sea.

Our initial goal for survey of the R/Js, was to survey both the extensive shallow bank on the western side of the islands, and also try to get a good idea of what conch populations looked like in the deeper water on the eastern side of the chain. It’s always good to have a plan, but we’ve learned to be flexible when it comes to the weather. After only two days of surveys, we decided it was too windy, and therefore too rough to continue exploring the deeper shelf side. Instead, we focused on the very productive banks. It was sharky out there too!

All of the information we got from the Department of Marine Resources and fishermen indicated that most of the conchs were found in the shallower waters, so we felt sure we were going to find some. As we worked our way down the islands from Water Cay, staying a night or two in the few protected anchorages we could find, we were amazed at the numbers we were seeing. It was not unusual for us to count 100+ conch on a single transect tow, which translates into high densities and healthy reproductive populations.

We had a great crew of volunteers this year. They were so capable and so brave to do the hard work that needed to be done in this remote location. Getting in and out of the water all day, every day, trying to avoid the barracudas and sharks, bouncing along in a small boat in rough conditions, and free-diving sometimes up to 40 feet to retrieve conchs for measuring…all for conchservation! At the end, everyone appreciated what the life of a fisherman must be like; except for the part where you get to sell your catch! More mini-reports coming soon!

The next generation

In many schools throughout The Bahamas, teachers and students are starting out this year with a greater knowledge of a beloved marine resource, the queen conch. Thanks to efforts by Bahamian conservation organizations that decided to put special focus on conchs in their summer camps and workshops, the next generation will know more about the biology and ecology of the species, as well as the threats to its survival. Summer camps for kids were held on the islands of New Providence, Andros, Abaco, Grand Bahama, San Salvador, and Eleuthera. On Andros, the Bahamas National Trust (BNT) held a special “Conch-servation” Eco Camp.  The Bahamas Reef Environment Educational Foundation (BREEF) and Friends of the Environment also held camps that included lessons on conch and marine conservation. Several teacher-training opportunities offered by the BNT and BREEF gave the country’s educators a chance to get hands-on experience and add a few conch-related activities to their classroom repertoire. Community Conch was able to attend several of these workshops to present our research and discuss conch conservation with the teachers. At BREEF’s annual marine conservation teacher training workshop we piloted a citizen-science program that will help raise awareness about the illegal and unsustainable harvest of juvenile conch. The camps, workshops, and citizen-science project are all part of an effort to bring conch conservation to the forefront in The Bahamas.  You’ll be hearing more about an organized campaign in the coming months. In the meantime, check out the pictures below and don’t forget check out our Facebook page for conch news updates.

New video – watch and learn how to estimate the age of a conch!

So, what happens when the weather keeps us from getting out there and counting conch? Usually its data entry, catching up on email, lab work, checking the weather forecast, more data entry, checking the forecast again…mostly we’re behind the computer, but sometimes we get a little creative. Chris and Dunte arrived In Sandy Point just in time for the effects of a tropical storm, so they had lots of time to hone their acting skills and shoot an outreach video about one of the most interesting things they learned in their volunteer training…how to estimate the age of a conch. They also wanted to make sure they got out an important message. Take a look and share with people who might be interested!

Meet Brandon, Tow Master

Brandon Jennings recently graduated from C.V. Bethel High School, where he participated in their highly regarded marine science magnet program. He spent the last year as a Bahamas Environment Steward Scholar (BESS Scholar) attending the Island School and completing an internship with the Bahamas National Trust. For a 17 year old, Brandon has a lot of field experience and it shows! On late notice, he joined our project in Abaco and played a critical role in getting surveys done on the fishing grounds of More’s Island. Despite the remote location and sometimes challenging weather conditions, he averaged 11 tows per day! Definitely tow master standards. Brandon says he’s always wanted to study queen conch because he learned when he was younger that their populations have been decreasing. He was ready when the opportunity to help us came up and made a huge contribution to our effort. Thanks Brandon!

Connecting with the community

When Community Conch visits a a location to conduct surveys, we also set a high priority on meeting with the people who are in touch with the resource on a daily basis. These folks might be fishers, fisheries officers, restaurant owners, other scientists, and local conservationists. By connecting with them, we get a better idea of things like fishing pressure, market trends, conch population trends, important fishing areas, and of course, all of the concerns and opinions that these stakeholders are willing to share. Our work in the Bight of Abaco was centered around two settlements, Sandy Point and More’s Island, which are both are very reliant on their lobster and conch fisheries. A high percentage of the men in these communities are fishermen, and so it was our goal to hear directly from them. We also wanted to make sure they knew what we were up to on their fishing grounds! Here’s a picture of the public meeting in Sandy Point, and a few that illustrate the fishing lifestyle of the two settlements.

A speedy conch…

…can only move this fast! Even though a large part of the conch’s body is one big muscle, they don’t exactly flee from predators. When they’re small they bury themselves in the sand to avoid being eaten by animals like rays and lobsters. When they grow bigger, their strategy is to hide inside their thick shell. Unfortunately for the conch, that big shell may make them more visible to their #1 predator, HUMANS. And where there’s one conch, particularly during the summer mating season, there are likely many more in the area because conchs mate in large aggregations. Hundreds or even thousands of individuals might be found in an aggregation, and all they can do when they see YOU coming is retreat into their shell. And well, we’ve gotten pretty good at getting them out of the shell. Check out this “Great Conch Race”on conchsaladtv.com

 

 

Training camp…can you spot the conch?!

Welcome Dunte Rolle and Christopher May! As of today, we have two new volunteers here in Sandy Point. Being new to the conch towing business, we put these two recent high school graduates through our “rigorous” training camp as soon as they arrived. Not only do you have to be able to spot conch like these within a transect while getting dragged through the water…

Can you spot the conch?

…you’ve got to learn how to categorize conchs as a juvenile, subadult  (roller), or adult, and identify mating behavior and spot egg masses. We also measure the size and lip thickness of quite a few conch shells, so you’ve got to learn how to use the calipers. During our afternoon boot camp, Dr. Stoner showed the guys the ropes and they are ready to go this week!

Dr. Stoner explains the stages of the conch life cycle after collecting a few examples.

Training...three to a tow.
