Trawl net is a bag-shaped gear towed through water, the mouth of which is kept open either by a frame or beam or otter boards and floats or kites and sinkers or weight. Sometimes the opening is effected by dragging the net with two boats. According to the habitation of fish in sea, trawl net is operated either at the bottom or in the midwater. For fish living in the bottom, bottom trawls are operated. Shrimps, flatfish, sciaenids, ribbonfish, carangids, perches etc. are caught by bottom trawls. For catching pelagic fish such as sardine, silver belly, anchovies, ribbonfish, shallow water mix etc. midwater trawls can be used. In India there are 35,000 mechanised boats most of which operate bottom trawl. Besides mechanised boats, there are 180 large vessels operated as outrigger trawlers for shrimp and stern trawlers for cuttle fish beyond territorial waters and offshore seas.
