Small fish have a big role. Fisheries for sardine, herring and anchovy species collectively produce more yield than any other fisheries worldwide and account for about one-third of total global catches arriving in ports. These fisheries span the globe and are critical for supporting livelihoods, aquaculture, food security, ecotourism and terrestrial animal husbandry (many catches are used to make fishmeal and fish oil).

Science is at the core of the sustainable management and conservation of Mexico’s marine resources

What if scientists, governments and citizens had access to a database that held everything we know about our oceans? This snapshot of the current state of science would be invaluable to understand the state of ocean health, would help build scientific solutions to climate-driven ocean problems and could spur new collaboration and amplify current conservation efforts.

Luckily for all of us passionate about the oceans in Mexico, this amazing database is not just a fantasy. It is now a reality in Mexico thanks to the collaborative efforts of Environmental Defense Fund (EDF) and Mexican researchers from several institutes including the University of British Columbia and the Mexican National Commission for the Knowledge and Use of Biodiversity (CONABIO).

New wave of Electronic Monitoring projects in U.S. fisheries highlighted at national workshop

emThe second national electronic monitoring workshop was held in Seattle, Washington late last year. Hosted by NOAA Fisheries, the goal was to bring together fisheries monitoring and management experts to share what’s working in EM implementation projects, what’s not, and to develop solutions and paths forward.

The workshop was also a celebration of significant progress taking place. Since the first national workshop held in January 2014, there has been a large scale EM regulatory program implemented in the Atlantic HMS fishery and regulations authorizing EM programs developed through Regional exempted fishing permit and cooperative research projects are scheduled for implementation in 2017 and 2018 in several different fisheries around the country.

These new programs all provide examples of one or more ‘best practices’ for EM, such as user-centered design approaches, clear goals established at the outset, and consistent collaboration among stakeholders. Read More »

New process helps managers make informed decisions, even in data poor fisheries

The coast of Galicia, Spain where octopus, goose barnacles, and many other species are harvested by small scale fishermen and women.

The coast of Galicia, Spain where octopus, goose barnacles, and many other species are harvested by small-scale fishermen and women.

Fishery managers, scientists and NGOs from all over Spain gathered in Madrid on a warm spring morning at a workshop convened by EDF and World Wildlife Fund Spain, eager to learn about how to collect, analyze, and use data to manage fishing mortality so that they could achieve their goal of good yields sustained over many years and even generations.

Like many people struggling to improve fishery outcomes around the world, the participants in this workshop felt like they couldn’t use the complex fishery assessment models they had learned in school because the data they actually had in hand were quite limited – and the models required rich streams of data.  The vast majority – probably over 80% – of the world’s fisheries appear to be in this situation.  The participants also felt like they had to make important management decisions with limited expertise by wading through a mass of technical papers on a variety of topics, none giving clear and specific guidance for the specific fisheries they care so much about.

Over the course of three intense days, participants worked together to synthesize guidance from the literature and from other fisheries on how to monitor fisheries, choose appropriate analytical methods and use the results to manage fisheries.  Together, we worked out how this guidance could be applied to specific fisheries.

We were thrilled to read the evaluations afterward.  Participants got a tremendous amount out of the workshop, but many of them said that it was too short (even though most of us were exhausted by the long days of thinking hard and practicing various skills).  They wanted to dig deeper and build on the skills that they had learned.  It would have been great to have a large body of international expertise on monitoring, data analysis and how to adjust fishing mortality to achieve fishery management goals in one convenient place that could be tailored to the fisheries that they care most about.

FishPath: Guiding managers in complex, data poor fisheries

Fortunately, a working group of international stock assessment experts convened by the Science for Nature and People program foresaw this need and developed a process called FishPath that does exactly that.  FishPath  elicits key information about a specific fishery and then uses that information to identify monitoring, assessment and harvest control options that will likely be appropriate for that fishery.  Read More »

Sharks need smarter management and better data to recover and thrive

Shark advocates at Oceana recently sued the National Marine Fisheries Service (NMFS), claiming that the way the agency controls fishing on dusky sharks violates the Magnuson-Stevens Act.  Duskies are overfished and have suffered overfishing for years, even though it is illegal to retain them if they are caught.  The duskies’ plight highlights the shortcomings of bans and similar efforts when it comes to protecting vulnerable species like sharks, especially when they are caught alongside other, healthier species.

Over the last several years, more and more people have learned about both the importance of sharks and the ongoing threats to their existence. This is great news because sharks are among the most important creatures in the ocean, playing a vital role in maintaining healthy marine ecosystems.  Plus, they’re really cool.  Formerly of interest exclusively to fish geeks like myself, Shark Week is now a widely celebrated summer ritual.  Shark finning, a deplorable practice where a shark’s fin is removed and the rest of its body is discarded at sea, has been banned in the United States since 2000, and more than 70 other countries have enacted similar bans.

Despite this progress, shark populations remain threatened and overfishing is common. The FAO reports that the market for sharks has actually increased, and many sharks die as bycatch as a side effect of fishing for other species at healthier population sizes, such as Atlantic swordfish (which has recovered after a focused conservation effort).

It’s Time to Take New England’s Groundfish Fishery Out of the Dark

What every fishing port in New England has long feared has now come true: the iconic cod fish is disappearing in our waters. If our shared goal is to rebuild a sustainable fishery for years to come, then we need to better understand what is happening to the fish stocks. This calls for better science, which has been the subject of discussion for years.

A key foundation of better science is better catch monitoring.  Inadequate catch data is the Achilles heel of the groundfish fishery in New England – particularly with cod – and the only way to improve this in a cost-effective way is through a comprehensive monitoring system that uses video technology.
