SEAFOODNEWS.COM [The Editor’s View] by John Sackton — Nov 3, 2015 — The following headline came across our newsfeed this morning “Some South China Sea fish ‘close to extinction'”, courtesy of Agence France Presse.
The report was based on a quote from Rashid Sumaila, director of the Fisheries Economics Research Unit of the University of British Columbia.
“The South China Sea is… under threat from various sources. We need to do something,” said Sumaila.
“The most scary thing is the level of decline we have seen over the years. Some species (are facing) technically extinction or depletion,” Sumaila, who headed the study, told a press conference in Hong Kong.
Having not seen the paper, it is not possible to evaluate his statements. But they are readily taken up because they feed into a media narrative that has proved very hard to change: fisheries around the world are dying because of human greed and overfishing. This narrative has been central to NGO campaigns focused on fisheries.
For many years, there was no organized response, and especially no way for journalists to get accurate scientific information. If they were fed a quote, such as “90% of the worlds stocks were unsustainably harvested” as appeared in Newsweek this summer, or that fish is ‘aquatic bushmeat’ comparable to eating monkeys and rhinoceros, as was said by Sylvia Earle, they have no way to evaluate its truthfulness. No wonder that seafood seems so controversial.
A group of scientists has come together through Ray Hilborn and his colleagues at the University of Washington, that is finally providing real-time commentary and rebuttal – i.e. pointing out the basic science – which in many cases does not support these media stories.
Our companion story today by Peggy Parker has more detail on Hilborn’s rebuttal to Newsweek, where he said one article ‘may set a record for factual errors’.
The idea is not to simply point out poor science and unsupported conclusions, but to encourage media to use their website cfooduw.org, as a resource whenever they see a scientific claim about fisheries.
For example, just in the past few days, scientists from around the world have posted comments on a range of global topics.
Hilborn pointed out, and the Newsweek editors accepted, a correction that not 90%, but 28.8% of fish stocks were estimated as overfished. Would they have run the story if they had not been pitched intitally that 90% of fish stocks have collapsed?
Steve Cadrin of the University of Massachusetts comments on recent articles about cod in both New England and Newfoundland. He says “The lesson from both of these papers is that rebuilding the stocks to historical levels depends both on fisheries management … and on the return of favorable environmental conditions.”
“Stock assessment models are simplifications of a much more complex reality. Stock assessments typically assume that components of productivity (survival from natural mortality, reproductive rates, growth) are relatively constant. These assumptions may be reasonable for relatively stable ecosystems. However, considering the extreme climate change experienced in the Gulf of Maine, such assumptions need to be re-considered. Alternative approaches to science and management are needed to help preserve the fishing communities that rely on Gulf of Maine cod.”
Two tuna scientists collaborate on a story in response to the charge by Greenpeace that John West is breaking its sustainable tuna pledge by buying fish caught with FADs.
FADs are a type of fishing gear (radio monitored fish aggregating devices) that have become very widely used for pelagic tuna. The two scientists, Laurent Dagorn and Gala Moreno, point out in a comment and a recent paper the important issues with FADs are 1) quantifying, with scientific data, how big that impact actually is, 2) determining if the impact is acceptable for the amount and diversity of fish caught, 3) comparing it with the impact of other fishing gears, and 4) implementing measures to reduce an impact if it is too high for the ecosystem, taking into account all fishing impacts.
This provides a real road map for a discussion of FADs and how they should or should not be used, in contrast to the campaign claims that they are simply destructive types of fishing gear. Dagorn and Moreno point out that all food production (including organic farming) involves making choices about modifying ecosystems, and tuna fishing should not be considered in isolation, but in how it meets the goal of providing food for global populations.
Aggregating and making this kind of fisheries science easily accessible is one of the most concrete actions that has been taken in years to counteract the misinformation that so many of us in the industry experience every day.
It is an effort that deserves wholehearted support, including publicizing the resource to local writers and editors. Please visit their website at cfooduw.org.
