A study by marine scientists at Rutgers, the state university of New Jersey, USA, has revealed that species of fish that have been overfished can recover to healthy levels if fisheries managers put effective limits on the catch. Scientists had previously thought overfishing over a long period of time might compromise the ability of stocks to rebound since many of the largest and oldest members of a species, those that contribute most to reproduction, are caught.

A new study by Rutgers University shows that fish species that have been overfished for decades can be brought back to health more easily than originally thought, once limits are placed on fishing. Marine scientists reported that a fish stock’s ability to recover from overfishing is enhanced even if it has been moderately overexploited for decades, possibly allowing for a quick recovery if sensible catch limits are enforced. Philipp Neubauer, a postdoctoral scholar, and Olaf Jensen, an assistant professor of marine and coastal sciences, claim the key is in the adaptation of fish to overfishing.
