Healthy Fisheries Need Sound Science, Good Policy and Stable Markets

Cape May1By:  Alexis Rife & Jake Kritzer

Any fishery functions as a series of complex interactions among an ecosystem, the political arena, the economy, cultural norms and traditions, and other systems. Understanding these interacting systems is critical for achieving EDF’s triple bottom line goals: more fish in the sea, more food on the plate, and more prosperous communities. EDF has been tackling this challenge by bringing together expertise spanning disciplinary boundaries, including biology and ecology, social sciences, policy analysis, and business planning.  Members of EDF’s Fishery Solutions Center recently spent two days in Boston meeting with partners from Yale University, the Massachusetts Institute of Technology (MIT) and the Natural Resources Defense Council (NRDC) to integrate research efforts in support of sustainable fisheries worldwide.

Participants reviewed the recent global macro-analysis of the biological, social and economic upside that can be realized by aligning incentives in fisheries through the application of well-designed fishing rights.  We then considered three parallel analyses that allow deeper understanding of how to best design scientific, policy and market systems that allow for the upside to be realized.

Exploring opportunities for ecosystem-based management of U.S. nearshore tropical reef fisheries

There is a general consensus that transitioning to ecosystem-based fisheries management will result in better outcomes for both marine ecosystems and the people who depend on them.  But what exactly does that mean, and how exactly can fisheries management get there?

Ecosystem-based fisheries management has been thoroughly debated and there are many aspects to it.  But one thing seems clear. When developing conservation and management goals, the entire ecosystem should be considered rather than just an individual fish population.

To actually achieve such goals, scientists and managers would need to quantify fishing targets and limits and then take actions intended to maintain fisheries and the ecosystem within a “safe operating space” associated with the maintenance of a variety of ecosystem goods and services. In our new publication, we have moved one step closer to identifying these fishing targets and limits for management in multi-species fisheries in coral reefs. Read More »

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.

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.

Expedition Cuba Part 2: Scientists Partner with Fishermen to Explore Cuban Waters

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!

Sound Fisheries Management is No Fluke

 

Summer Flounder

Recently a US Senate subcommittee held a hearing entitled “Developments and Opportunities in US Fisheries Management,” with testimony by federal, regional and state officials that focused on the need for collaboration in fisheries management and decision-making based on sound science.  More than two and a half hours of testimony and questioning by Senators focused on the role of science and the Magnuson Stevens Act in effective management of our nation’s fisheries, especially summer flounder or “fluke.” 

New York and New Jersey have long been embroiled in an interstate conflict over what New York Senator Chuck Schumer has called “our decades long fight to bring fairness, flexibility, and accountability into the management of summer flounder.”  To that point, a reoccurring theme in the testimony was that effective fisheries management requires high quality data and regular stock assessments.  This notion was also echoed at a House Natural Resources Committee hearing a week earlier.

What is clear in the early hours of debating MSA’s reauthorization is that stakeholders across the board are focused on a common top priority – simply, good science is fundamental to good management.  This reality is at the core of the interstate summer flounder battle, with NY arguing that the use of outdated data has led to an unequal allocation of fish between states.
