A powerful, long-term study from WCS adds scientific backing for global calls for conserving 30 percent of the world’s ocean. The studied no-take marine protected areas (MPAs) increased the growth of fish populations by 42 percent when fishing was unsustainable in surrounding areas, achieving the benefits of stable and high production of fish populations for fishers, while protecting threatened ecosystems.
The study recorded fish catches for 24-years across a dozen fish landing sites within two counties in Kenya, which allowed scientists to evaluate the long-term impacts of two different fisheries management methods. While one county utilized a no-take MPA covering 30 percent of the fishery, the other focused on gear restrictions and prohibited the use of small-mesh nets.
The differences in outcomes for the fishers and the ecosystems were stark. Per-person daily catches rose 25 times faster near the no-take MPA than in fished areas with gear restrictions, showing that no-take MPAs were far more effective at sustaining stocks of fish than restricting destructive gear.
