With support from the Waitt Foundation, EDF launched an initiative last year with the University of Havana’s Center for Marine Research that allowed teams of Cuban, U.S. and Mexican scientists to carry out a series of expeditions to conduct vital new research on Cuba’s remarkable—but understudied—marine and coastal ecosystems. 

A Special Caribbean Reef

Coral reefs are some of the world’s most imperiled marine habitats.  Impacts from climate change, pollution, overfishing and resource extraction combine to threaten reefs all over the world.  This is especially true in the Caribbean, where rapid development is underway across the Caribbean Sea, exacerbating the stressors on coral reefs and their related seagrass and mangrove ecosystems.

However, in one special corner of the Caribbean, the Gardens of the Queen archipelago, has remained remarkably resilient in the face of this collective pressure.  A Caribbean marine paradise, The Gardens consist of more than 600 cays and islands and is home to the largest contiguous reserve in the Caribbean at 2,170 square kilometers.  It supports a mosaic of mangrove, seagrass, patch reefs, fringing red and reef slope and is abundant with fish, sharks and other marine life.

To reach the Gardens of the Queen from mainland Cuba, one must bisect the Gulf of Ana Maria, a shallow-water system comprised of mangrove, seagrass and coral reefs. The ecosystems of the Gulf of Ana Maria and Gardens of the Queen together cover more than 10,000 square kilometers of productive habitat, making the entire archipelago a magnet for eco-tourism, including SCUBA diving and recreational fishing. Despite a growing eco-tourism industry and offering one of the best examples of a resilient Caribbean reef, much about the Gardens remains a mystery.

We are excited about our partnership with the University of Havana’s Centro de Investigaciones Marinas (CIM) and the Centro de Investigaciones de Ecosistemas Costeras (CIEC), and the potential for collaborative scientific exploration to yield foundational data  and information about marine habitats in and around the Gardens of the Queen.  Our inaugural expedition in (February) 2013 harnessed expertise from a tri-national team of scientists, which shared knowledge and scientific methods while surveying migratory shark populations off Cuba’s south coast in the Gulf of Batabanó, to the west of the Gardens of the Queen.  In October 2013, scientists from the three organizations hopped aboard the RV Felipe Poey and RV Itajara to journey to the Gardens reserve itself, and the nearby Gulf of Ana Maria.  This 19-day expedition produced new data about the special Gardens ecosystems, and shared expertise among scientists from the three organizations, promoted collaboration, increased scientific capacity and forged new friendships.

Maximizing Limited Data to Improve Fishery Management

By Ashley Apel

According to a recent study published in Science, nearly 80% of the world’s catch comes from “data-limited” fisheries.  Not surprisingly, research shows that many of these fisheries are facing collapse, jeopardizing the food security of hundreds of millions of people in developing countries who depend on seafood for a majority of their dietary protein.

Historically, fisheries with little data had few science-based management options. But new methods are being continuously developed and used in the field that deliver science-based results, even in the absence of long-term, historical catch data. Since fishery stock assessments can be extremely complex, EDF recently developed a user-friendly, six-step framework as part of an overall guide to Science-Based Management of Data-Limited Fisheries.

The framework outlines a systematic approach that fishery managers can use to conduct quick and relatively inexpensive assessments.  The methods allow stakeholders in data-limited fisheries to estimate risks to marine ecosystems, determine vulnerability of a stock to fishing pressure, calculate the level of overfishing, assess the sustainability of the fishery, and establish sustainable fishing targets and other management reference points.

Download the guide on Science-Based Management of Data-Limited Fisheries or download the entire toolkit for fisheries.  Feel free to send questions or comments to catchsharequestions@edf.org.

Expedition Cuba Part 3: Collaborative Research Establishes Baseline Monitoring in Cuba

Cuban and Mexican researchers, Alejandra Briones and Ivan Mendez, look at a sample that will be analyzed in CIM’s lab to assess the faunal communities in the water column.

By: Kendra Karr and Valerie Miller

Part III of a blog series detailing a February 2013 Research Expedition in Cuba organized by EDF Oceans’ Cuba, Science, and Shark teams and funded by the Waitt Foundation. A team of scientists from Cuba, Mexico and the U.S. along with EDF staff set sail to share knowledge, scientific methodologies and to survey shark populations in Cuba. The tri-national expedition was led by Cuban scientists from University of Havana’s Center for Marine Research (CIM) and U.S. scientists from the Mote Marine Laboratory in Florida.

Researchers from Cuba, Mexico and the U.S. participated in an exploratory research cruise in the Gulf of Batabanó along the Southern coast of Cuba to monitor shark populations, local faunal communities and to train fellow team members in monitoring techniques.  Leaving the port of Batabanó, the RV Felipe Poeytransected the shallow, soft-sediment habitat that comprises the majority of the Gulf.  The cruise set off for the remote and sparsely populated Isle of Youth, the largest island in the Canarreos Archipelago.  Canarreos Archipelago is home to a national park and several marine protected areas (MPAs) which contain habitats that possess ecotourism potential and provide refuge for ecologically and economically important species such as lobsters, sharks and finfish.

Part II of a blog series reporting on the February 2013 Research Expedition in Cuba organized by EDF Oceans’ Cuba, Science, and Shark teams and funded by the Waitt Foundation. A team of scientists from Cuba, Mexico and the U.S. along with EDF staff set sail on an exploratory research cruise to share knowledge, scientific methodologies and to survey shark populations in Cuba. The tri-national expedition was led by Cuban scientists from University of Havana’s Center for Marine Research (CIM) and U.S. scientists from the Mote Marine Laboratory in Florida.

In early February the team of researchers boarded the RV Felipe Poey and departed the south coast of Cuba for the Gulf of Batabanó.  The nine-day expedition was designed to monitor shark populations, collect baseline data on plankton and benthic communities and train scientists in data collection techniques for future monitoring.  It took the entire first day to steam to the Isle of Youth.   By the evening the smooth waters and night sky had blended into one endless black landscape. As a sense of isolation set-in, the boat turned towards some lights in the distance – which emanated from a lobster station floating in the middle of the Gulf.  After a day crossing the ocean with no land in sight, it felt strange stepping off the boat and onto the deck at the station. The lobster fishermen, friends of the Cuban scientists, showed us around the facility which stores their daily catch in pens.  This moonlight meeting was just the first of many productive interactions with fishermen throughout the journey.

Intro by Dan Whittle: With generous support from the Waitt Foundation, Environmental Defense Fund (EDF) has launched a new initiative to support collaborative field research with scientists from the University of Havana’s Center for Marine Research. This initiative is enabling teams of Cuban, U.S. and Mexican scientists to carry out a series of scientific expeditions to conduct important new research on Cuba’s remarkable—but understudied—marine and coastal ecosystems. This effort will also support year-round port sampling of shark fishery landings at Cuban ports, contributing to EDF’s overarching tri-national shark conservation efforts throughout the Gulf of Mexico.  

On our inaugural expedition in February 2013, our tri-national team embarked on a research cruise off of Cuba’s south coast in the Gulf of Batabanó to share knowledge and scientific methods, and to survey migratory shark populations. The expedition was organized by EDF Oceans’ Cuba, Science, and Shark conservation programs and led on-the-water by scientists from University of Havana’s Center for Marine Research (CIM) and from the Mote Marine Laboratory in Florida; with participation by a scientist from Mexico’s College of the Southern Frontier (ECOSUR).

Results from this expedition will be highlighted in a 3 part blog series. Today’s post focuses on sharing science in data-limited shark fisheries.  It will be followed by stories about the partnership of fishermen and scientists and baseline data.  Join the journey here and follow along this week!

This month’s ocean watch essay comes to us from theEnvironmental Defense Fund(EDF), and was written by:Dan Whittle the senior attorney at Environmental Defense Fund and director of its Cuba ProgramDoug Rader, PhD, EDF’s Chief Oceans Scientist, and Violet Dixon the Marketing Communications Associate for EDF’s Oceans program. All images by Noel Lopez Fernandez.

In the waters off the Southeast coast of Cuba there’s a near-pristine coral reef reserve called Jardines de la Reina, or the Gardens of the Queen. In this national park, groupers, snappers and many other reef fish flourish, along with several species of sharks. Although many of the world’s best-known reefs face destruction in the face of global warming and other threats, large portions of the Gardens of the Queen remain remarkably healthy. Relative isolation from human influence helps make Cuba’s coral reefs unique. Protecting these ecosystems — and species that rely on them — requires careful collaboration and cooperation among managers, scientists, fishermen and local fishing communities. Well-designed marine protected areas (MPAs), combined with innovative fisheries management, are the foundation for both sustainable commercial and recreational fisheries and a thriving eco-tourism sector.The abundance of big predators, like these Caribbean reef sharks, is a sure sign of an ecosystem in balance. The Gardens has six to eight times as many sharks as elsewhere in the Caribbean.

Seeing under the sea
Healthy coral reefs, mangrove swamps and seagrass beds support thriving fish populations, which in turn support local fishing communities and attract ocean enthusiasts. Scuba divers come from around the world, for example, to witness the myriad of sea animals and breathtaking underwater ecosystems in the Gardens of the Queen.

On these dives, they encounter numerous species of shark including Caribbean reef sharks, silky sharks, nurse sharks and occasional lemon and blacktip sharks.  Depending on the season and other factors, visitors also occasionally encounter whale sharks, the largest known fish species. Read More »
