A variety of fishing methods are used. Some of the most controversial include trawls, dredges, purse seining, and gillnetting. These fishing strategies involve large nets that entangle not only fish, but other animals (bycatch) such as turtles, dolphins and sharks. Also, dredges and trawls damage marine environments by scraping the bottom of the seafloor (3, 5.) To learn more about today's fishing methods, see the Monterey Bay Aquarium website.
