‘Breakthrough’ research suggests protecting a third of a fishery with ‘no-take’ rule leads to huge boost in surrounding fish populations

No-take marine protected areas increased the growth of fish populations by 42 per cent when fishing was unsustainable in surrounding areas

A long-term study hailed as a “breakthrough” by scientists suggests tightening fishing restrictions in one area can rapidly boost fish populations in surrounding areas and simultaneously protect threatened ecosystems.

The “powerful” findings provide clear scientific backing for global calls to conserve 30 per cent of the world’s oceans, the research team said.

The study, carried out in Kenya, recorded fish catches over 24 years across 12 fish landing sites in two different counties.
