How to keep fish in the sea and on the plate June 18,2019   |  Source: EurekAlert

Temporary bans on fishing can be better than permanent ones as a way of allowing fish stocks in an area to recover, while still providing enough to eat, a research team has found.

A new study published in the Journal of Applied Ecology by researchers from the California Polytechnic State University San Luis Obispo (Cal Poly), WCS (Wildlife Conservation Society), Swansea University, the University of Rhode Island (URI) and other groups has revealed that the challenge of keeping fish in the sea while putting fish on the plate might be best achieved through fishing grounds with closures that are periodically subject to pulse harvests.

The new research could help revolutionize fisheries management and settle a long-running debate between fisheries management and conservation sectors about the role of marine protected areas (MPAs) in balancing potential for stock recovery and maintaining yields.

At the crux of the matter is the current model of fishing closures. Conservationists have argued that permanently closed, no-take MPAs are an effective means of mediating overfishing and allowing stock replenishment, and many global conservation agencies are thus calling on high levels of protection in 30% of the world's oceans.

However, MPAs can shift fishing effort into
