Worldwide, there is considerable interest in developing fishery management options that balance social, economic and ecological goals for multispecies fisheries. Ideally, fisheries management should strive not only to produce good yields from single stocks, but also to avoid serial depletion and prevent adverse impacts of fishing on marine ecosystems — a difficult, but achievable task.

In many fisheries, many species are caught at the same time. These are called multispecies fisheries, and the fact that they catch many species together, with the same gears, means that the different species are caught at the same rate. The trouble is, some species are productive enough to withstand high catches while others are not. So as a result, the low-productivity species get fished out, reducing overall yield, markets for diverse species and economic and ecological resilience — resulting in serial depletion. While many single-species fisheries are becoming more sustainable thanks to science-based management strategies, multispecies fisheries often face greater sustainability challenges, and these challenges will grow in the face of climate change.

After an hour of flying in a small plane across the Pacific Ocean with no land in sight, we began to wonder how much farther it would be before we would see land again. About two hours into the flight, the peaks of one of the three volcanic islands rose above the local cloud cover, indicating that we were arriving at the Juan Fernández Islands off the coast of Chile. As we got closer, we saw the first and largest of the islands: Robinson Crusoe Island. Read More
Coral reefs play many important roles for marine ecosystems and communities, including for biodiversity, fishing, recreation and tourism. They are a source of livelihoods to communities all over the world. Their beauty and ecological importance inspire citizen scientists globally to get involved in reef health monitoring and projects that help ocean ecosystems.
However, coral reefs worldwide face an uncertain future, with many reefs reportedly transitioning from being dominated by corals, to being dominated by macroalgae. This transition threatens all of those who depend on healthy coral ecosystems around the world. This new research, which I contributed to, reveals that we may have more opportunities to save corals than previously thought. Read More
Small scale fisheries are critically important for the provision of food security, livelihoods, and economic development for billions of people. Most of these fisheries appear to be under-performing with respect to conservation, food production, revenue, and the quality of the livelihoods they can support.
Many factors related to successful small-scale fisheries management have been articulated in previous research and through practical e xperience, including strong leadership, co-management, secure catch or marine tenure privileges, and scientific assessment of fishery status. Both the pathways and tools employed in fishery reform vary, but there is a growing consensus that the integration of effective fisheries governance and science-based management is crucial for success.
Together with fishermen and women, community members, managers and scientists we have identified some major lessons that arise from case studies in Belize, Cuba, Mexico and the Philippines. In newly published research, my colleagues and I evaluate the stories, challenges and lessons learned from these fisheries, where these groups are developing science-based solutions for sustainable fishing. We found that successful science-based management includes fisher participation and empowerment, partnership across sectors and community buy-in, and sound scientific analysis. Read More
Workers help grow and maintain soft crabs that are purchased by surrounding mangrove islands within the Myeik archipelago.
Myanmar is a nation with a diverse array of ecosystems, each contributing significantly to local livelihoods, food security and culture. There is tremendous potential for Myanmar’s fisheries, if sustainably managed, to support the ecological, economic and social welfare of its people. The transition to sustainability will require an overarching plan that includes the use of new data collection and fisheries management tools to overcome the challenges these fisheries face and help them reach their full potential.
New science and collaborations among EDF, WCS and Cornell build on efforts of the Thriving Marine Fisheries in Myanmar initiative, offering solutions to support Myanmar’s efforts to steward sustainable and productive fisheries.
