Performance of a bycatch reduction device in the shrimp fishery of the Gulf of California, Mexico

A square mesh/extended funnel bycatch reduction device (BRD) tested in the bottom trawl shrimp fishery in the Gulf of California decreased bycatch by 40% when compared to control trawls. On average, the BRD excluded 37% of finfish species, including the endangered Totoaba macdonaldi, but it also reduced shrimp catch by approximately 7%.
