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.

Eating with the Ecosystem: Gulf of Maine

Earlier this year, I wrote about an event held in my neighborhood by Eating with the Ecosystem, a new initiative that aims to educate seafood lovers about the environmental and culinary benefits of a diverse palate that incorporates a wide range of sustainable seafood choices.  After that dinner, I sat down with Sarah Schumann, the creator of Eating with the Ecosystem, to learn more about how her project emerged.

Sarah’s work is driven by a diverse and fascinating array of interests and experiences.  Her love of commercial fishing was born more than a decade ago when she lived on the coast of Chile and got to know the small-scale coastal fisheries of that seafaring nation.  Chile has enjoyed success in implementing cooperative and area-based allocation systems, which today are serving as a model for work being done by EDF, Rare and the University of California at Santa Barbara through the Fish Forever partnership.

Catch Share Design Center Releases New Toolkit for Fisheries

Fishermen and fishery managers often have few resources to help them navigate the tricky or challenging management decisions they regularly face.  That’s why the Catch Share Design Center has developed a comprehensive toolkit for designing and implementing management systems that can build resilient, profitable fisheries.

Back in 2010, we released the Catch Share Design Manual. It was the most comprehensive overview of catch shares, to date, and included a step-by-step process that stakeholders could use to evaluate their fishery and design a custom program suited to fit their specific needs.  Most importantly, it drew on the knowledge and experience of fisheries experts around the globe.

Since the Catch Share Design Manual’s initial release, we’ve heard from fishermen, managers and other fisheries stakeholders all over the world. Some of the feedback offered expertise and recommendations, while others sought advice and requested specific new research.  All of it was useful and this new toolkit is a response to those requests.

We all know that lack of effective management can be devastating to fish populations, the billions of people around the world who rely on seafood for protein and the millions who rely on the stability of the fishing industry to support their livelihoods.  By sharing this toolkit, we are providing fisheries stakeholders with the tools needed to recover fish populations and ensure that fisheries are sustainable and prosperous in the long-term.

New management plan continues to yield conservation & economic benefits in Pacific groundfishery: NOAA report

On September 24, NOAA Fisheries released their report on the second year (2012) of the West Coast Groundfish Catch Shares Program, a program that EDF has been instrumental in helping to develop, implement and improve. The report notes the spirit of partnership that helped bring a catch share management system to the Pacific Coast, and praises the program’s conservation and economic performance. Mostly, however, NOAA credits fishermen for using the flexibility afforded under catch shares to improve their long-term economic prospects and avoid overfished species.

Here are some highlights:

  • Conservation: The report notes “a significant reduction in the amount of bycatch,” of overfished species, and concludes that the program “is actively rebuilding several groundfish stocks.”
  • Catch: Harvest of target stocks continues to improve—up 5% from 2011.
  • Business Flexibility: Transfers of quota between fishermen increased dramatically in comparison with 2011, and were relatively constant throughout the year. This increase indicates better understanding among fishermen of how to leverage their allotment for efficient business planning. Read More »

Effective monitoring is critical for the New England groundfish fishery

Collecting timely, accurate and complete information from fishing vessels is fundamental to successful fisheries management.  There is an important nexus between the quantity and quality of data collected by monitoring programs that are used for fisheries science and management that makes it more credible to industry and other stakeholders.

EDF continues to work to improve the performance of New England groundfish sectors by supporting the design and implementation of a cost-effective and comprehensive monitoring program that incorporates the use of electronic monitoring (EM).  The current crisis facing the groundfish fishery with low stock abundance and resulting quota cuts, and high uncertainty of stock assessments, highlights the need to produce reliable fisheries information.

Closed areas can decrease uncertainty in effects of climate change on New England Fisheries

As fishermen around New England will be the first to point out, this summer, much like last year, has been abnormal. The ocean waters were warmer and cod, haddock, and flounders—the mainstay of our fishing industry for centuries—are increasingly elusive. There’s plenty of blame to go around, including decades of mismanagement and overfishing, inexact science and a mismatch in abundance of certain predatory species. Looking beyond these factors, the impact of climate change on fisheries is another factor driving fish abundance that’s worth a hard look.

The level of carbon dioxide in the Earth’s atmosphere has now exceeded 400 parts per million, contributing to rising ocean temperatures. Some of the fastest increases in the last few decades have occurred in the Northwest Atlantic, and 2012 registered the largest annual increase in mean sea surface temperature for the Northwest Atlantic in the last 30 years.  

It is clear that climate change is disrupting New England’s fisheries right now; it is no longer an abstract, future scenario.

In the face of this evidence, fisheries managers need to factor in climate change alongside fishing effort and other elements when determining how to manage and rebuild fish stocks. The impacts of climate change can prevent fisheries management inactions from rebuilding fish populations, and conversely, excess fishing pressure can hinder the ability of a fish population to adapt to changes in climate. As I have written recently, a network of well-designed closed areas represents a promising management strategy to address the effect of climate change on fisheries. Read More »
