By-catch: Just the facts... (Site not responding. Last check: 2007-11-07) |
 | | By-catch is a serious issue that can contribute to species endangerment (additional info and facts about species endangerment). |
 | | One example of by-catch is dolphins (Any of various small toothed whales with a beaklike snout; larger than porpoises) caught in tuna (Any very large marine food and game fish of the genus Thunnus; related to mackerel; chiefly of warm waters) nets. |
 | | As dolphins are mammals (Any warm-blooded vertebrate having the skin more or less covered with hair; young are born alive except for the small subclass of monotremes and nourished with milk) and do not have gills (Respiratory organ of aquatic animals that breathe oxygen dissolved in water) they may drown while stuck in nets underwater. |
