New research study: The snowball effect of overfishing

them unless we can get this problem under control."

The full study appears in the Dec. 23 issue of Proceedings of the National Academy of Sciences.

Travis and Coleman and their colleagues are hoping that their research will accelerate changes in how fisheries scientists approach these ecosystem problems and how fisheries managers integrate system issues into their efforts. They hope that more effort will be devoted to understanding the key linkages among species that set up tipping points in ecosystems and that managers look for data that can show when a system might be approaching its tipping point.

"It's a lot easier to back up to avoid a tipping point before you get to it than it is to find a way to return once you've crossed it" said Travis.

Fishing experts do generally understand how overfishing affects other species and the ecosystem as a whole, but it "needs to be a bigger part of the conversation and turned into action," Coleman said.
