Excluding fishermen can harm fisheries

09 March 2012


The problem with fisheries management is that what a government decides will be best for conservation may not be best for the local people that rely on a fishery, and may in fact end up harming the fish stocks in the end. A study published in the February edition of Scientific Reports has shown just this in a Gulf corvina fishery off the coast of Mexico.Mexican fishing boats

Brad Erisman, from Scripps Institution of Oceanography, and his colleagues used tracking systems to figure out the exact movements of the spawning fish, and of the fishing vessels, over time. They found that the peak in fish catch coincided with the peak in spawning activity.
