‘Bycatch’

The fish in grocery stores and restaurants aren’t the only casualties of the commercial fishing industry. Sharks, sea turtles, birds, seals, whales, and nontarget fish who get tangled in nets and hooked by long-lines are termed “bycatch” and are thrown overboard. They fall victim to swarming birds or slowly bleed to death in the water. Scientists recently found that nearly 1,000 marine mammals—dolphins, whales, and porpoises—die each day after they are caught in fishing nets. By some estimates, shrimp trawlers discard as much as 85 percent of their catch, making shrimp arguably the most environmentally destructive fish flesh a person can consume.
