A fishing vessel in Alaskan waters uses a seine, a large fishing net with sinkers on one edge and floats on the other. A small net boat tows one end of the net to encircle fish. The net is then closed on the bottom and pulled up by the main vessel.
Seiners, like trawlers, catch fish in nets. But on seiners, the mouth of the net is drawn closed before it is hauled aboard.
Seine fishing originated in Denmark in the middle of the 19th century and descended from casting nets from shore. Modern seiners normally operate throughout the North Atlantic Ocean, pursuing tuna and other fast-swimming species. They can also be found ranging across the warmer waters of the Pacific in search of tuna or off the coast of South America working the much depleted anchovy stocks (Seiners, Fishing Vessel in Alaskan, Seine Fishing Ships, Fishing Tuna Ships).
