Here’s proof fishing bans leave plenty to eat, says study of Mexico marine park

Scientists compared catch data from four years before and after a permanent ban and found minimal impact on commercial fishing

Banning fishing in a Mexican marine park did not reduce the fishing catch, according to a new study that says it has dispelled the myth" spread by fishing companies that protecting marine areas leaves less fish available for people to eat.

The before-and-after study looked at whether banning commercial fishing from the Revillagigedo national park, which covers 147,000 sq km (57,000 sq miles) of Pacific Ocean west of Mexico, would reduce the country's catch volumes.

The answer was no, said the study's authors, who said the finding showed that large, fully protected MPAs [marine protected areas] can contribute to a more sustainable and equitable use of the ocean, without major economic repercussions on the fishing industry".
