Grouper fisheries have high impacts on nontarget species, the Monterey Bay Aquarium reported. Bycatch can include sharks, black sea bass, blueline tilefish, smooth dogfish, giant snake eel, golden tilefish, gray triggerfish, greater amberjack, red porgy, red snapper, scamp, speckled hind, vermilion snapper and yellowtail snapper. Loggerhead sea turtles were getting caught in bottom longline gear but that is being addressed with monitoring and a reduction in gear. The red grouper fisheries use dehooking devices and circle hooks to reduce bycatch. Venting tools are also employed to make it easier for reef fish to survive when released.
