New England has received a lot of media attention recently about the fisheries disaster declared by President Barack Obama. The precipitous decline in groundfish in New England waters has created an imminent need to help fishermen and fishing communities that depend on stable healthy fish populations.
It is important to dispense with false rumors and to set the record straight. There is an effort on the part of some to claim that catch shares are somehow responsible for the New England groundfish population declines. To claim this is to suggest that fishermen have exceeded their catch limits and are not following the rules. This is simply not true. In fact, sector fishermen have been working hard to stay under their catch limits, and in some cases remain well below these limits.
In reality, the disaster declaration was based on the fact that there are changes happening in the ecosystem that are impeding the rebuilding of fish populations. We are forced to confront the frightening reality that fishing is changing in part because our oceans are changing. We are dealing with a resource problem, not a management problem. Read More

Yesterday, I recounted the recent history of assessments of the Gulf of Maine (GOM) cod stock that has led to a looming crisis for many New England fishermen, and the management response underway in the form of emergency action. Today, I discuss two major goals that will most effectively use the time before us to potentially change our understanding of cod status, and avoid or minimize socio-economic hardship.

Before the 2011 assessment had even been reviewed, a barrage of criticisms began to be levied. To be sure, many decisions made during the assessment could have gone a different direction, including data to include or exclude, values for key parameters, and determination of reference points. Renowned ecologist E.O. Wilson once observed that ecology is far more complex than physics, and fisheries science is a close cousin of ecology. There are few universal rules for how to assess fish stocks, and the discipline relies heavily on experience, professional judgment, vigorous debate, peer review, and trial and error. The GOM cod assessment was not lacking in any of those elements. In my view, the assessment was done right, was done well, and should be commended for achieving what it set out to do. Gerrymandering the assessment to get a more favorable outcome is both bad practice and bad policy. Read More

By now, most people concerned with fisheries management in New England, and in fact many others across the country, are aware of the difficult situation unfolding around the Gulf of Maine (GOM) cod stock. For those who are not, a stock assessment completed late in 2011 drastically altered our perception of the stock from the last assessment completed in 2008, and suggests that the resource is in much worse shape than we previously thought.
Actually, in many ways the 2011 assessment tells a story similar to the 2008 assessment: Biomass reached all-time lows during the 1990s, but then approximately doubled by 2001. Thereafter, biomass dipped again to another low point in the mid-2000s, before climbing again toward the end of the 2000s.
The critical difference between the two assessments lies in the pace of rebuilding since the recent low in the mid-2000s. The 2008 assessment suggested that the population was increasing extremely rapidly, with growth of more than 200% from 2005 to 2007. In doing so, it had exceeded the overfishing threshold, and was well on its way toward the rebuilding target biomass that would produce the maximum sustainable yield on a continuing basis. Read More
Elinor Ostrom, who shares this year's Nobel Prize for Economics, laid much of the intellectual foundation for EDF's current work with fishery cooperatives. Catch shares evolved from common property theory and empirical observations that, under certain conditions, resources such as fish, water, or pasture land tend to be overexploited when property rights are not clearly delineated. Ostrom's research shows that resource users can develop cooperative methods to avoid overexploiting resources and dissipating wealth through competition.
While some say that this idea "challenges" the conventional wisdom, research conducted by EDF's Ocean Innovations suggests that competitive and cooperative dynamics depend on scale and the attributes of the communities themselves. Our results will soon be published in the Bulletin of Marine Science. This research and our experience with fishermen on the water motivates our work with the Cape Cod Commercial Hook Fishermen's Association and the Morro Bay Community Based Fishing Association, two pioneering efforts to cooperatively manage fisheries.
We believe that cooperative approaches can complement catch shares, which often apply at larger scales and to more industrial, less socially cohesive fishing communities. Such approaches are also broadly applicable in many developing countries, where social values are emphasized over individualism and economic gain, and where legal and political structures facilitate the delegation of resource use privileges to groups.
