Killing Young Fish Results In Population Growth, Study Finds
If you kill more fish, the total population of the species declines. However, kill only small, young fish, the total number of small, young fish increases. This seemingly paradoxical conclusion has far reaching implications for the sustainable management of oceans, and is the result of a theoretical study conducted by a research team led by Prof. André de Roos of the Institute for Biodiversity and Ecosystem Dynamics (IBED), University of Amsterdam.

Want Sustainable Fishing? Keep Only Small Fish, And Let The Big Ones Go
Scientists at the University of Toronto analysed Canadian fisheries data to determine the effect of the “keep the large ones” policy that is typical of fisheries. What they found is that the effect of this policy is an unsustainable fishery. The whole article.
How close do your state’s regulations match with the research from those two articles?

Fish Health Claims May Cause More Environmental Harm Than Good, Researchers Say
The health benefits of fish consumption have been over-dramatized and have put increased pressure on wild fish, according to a new research published in the Canadian Medical Association Journal (CMAJ). Finish reading it here.
Of course, they keep missing the main benefits of fish “health claims” (at least, I claim these benefits to my wife all the time): It’s not the eating of the fish that gives the benefits, it’s the finding and catching of the fish that brings the benefits.
