More responsive fisheries management could help avert future collapses in fast-growing fish populations

A study of global fish populations has suggested fast-growth fish species are more vulnerable to population collapses than previously thought.

It had been assumed that life under the waves reflected life on land and that slow-growing species were most at risk.

The researchers found that overfishing was key, but making fisheries more responsive to environmental changes could help avoid future collapses.

The findings appear in the Proceedings of the Royal Society B journal.

"On the land, slow growing animals are at most risk of decline and we used to think the same was true in the oceans," explained co-author Malin Pinsky from Rutgers University, US.

You can think of it like a finely tuned race car travelling at 200 miles per hour - one wrong move and you'd be off the trackDr Malin Pinsky, Rutgers University

"But we studied more than 150 populations around the world and found that nearly the opposite was true."
