A U.S. federal appeals court has instructed the National Oceanic and Atmospheric Administration (NOAA) to reassess its Amendment 53 decision, which redistributed red grouper catch shares in the Gulf of Mexico. The order follows a lawsuit by commercial fishermen who claimed the reallocation favored the recreational-fishing sector and violated legal norms. The court identified issues with Amendment 53 and requested NOAA to provide a more detailed explanation of its decision, particularly concerning federal fisheries management law standards on conservation promotion and bycatch minimization.
