If you can't find it in yourself to care for beings smaller than yourself, think about this. When fishing for shrimp, nets are used, and oftentimes, shrimp are not the only animals that are caught. Many more sea turtles die every year than dolphins do in fishing nets. In fact, six of the world's seven species of sea turtles are now listed as endangered.http://www.sdearthtimes.com/et0296/et0296s2.html
About 850 whales, dolphins and porpoises die every day
due to fishing with nets.
Worldwide, fishermen throw away 25% of their catchhttp://see-the-sea.org/topics/commerce/bycatch.htm
"During long-line fishing, lines up to 80 miles long with over 30,000 baited hooks are set on lines behind the fishing vessel. Seabirds see the bait near the surface as lines are deployed. The birds dive on the bait, becoming hooked or stealing the bait. Tens of thousands are hooked and die each year ... In each of the last 3 years an estimated 2,000 Laysan Albatross and 2,000 Black-footed Albatross were killed in the waters around Hawaii. The U.S. Fish and Wildlife Service and National Marine Fisheries Service estimate that in the Bering Sea/Gulf of Alaska area 10,000 birds are killed annually. Short- tailed Albatross, an endangered species, are caught in the waters off Alaska and have been seen around Hawaii. In the southern oceans, it is estimated that over 40,000 albatross of several species are killed annually. Populations of Wandering Albatross, a species of special concern, are estimated to be declining by 10% annually owing to longline fishing. Other birds killed include petrels, skuas, gulls, kittiwakes, fulmars, shearwaters, and penguins."http://www.nmnh.si.edu/BIRDNET/OC/issues/OCBv1n4.html
"[The] Gulf of Mexico Commercial marine fisheries in the U.S. alone toss away up to 20 billion pounds of by-catch each year--twice the commercial and recreational catch combined."http://seawifs.gsfc.nasa.gov/OCEAN_P...l_bycatch.html
Sounds like a big waste to me. Such needless killing...
