dc.description.abstractDue to poor selectivity of commercial trawls, large quantities of fish are discarded in the sea. Impact of codend mesh size on trawl fishery has been studied by Rajeswari et al. (1998). The discards often consist of juveniles of commercially important species, which may impact on the yields of commercial species. Mesh size regulations for trawl gears aim to reduce fishing mortality by allowing small sized fishes and juveniles to escape. The shape of the mesh affects the selectivity of codend. The mesh lumen of the diamond mesh closes up under tension during towing operation and prevent escapement of fish. In the square mesh codends, the mesh will remain open and facilitate escapement of juveniles small szied fishes (Robertson, 1983; Robertson and Ferrow, 1988; Robertson and Stewart, 1988; Kunjipalu etal., 1994, Varghese etal., 1996; Prakash et al., 2008). Selectivity information is an important tool for fishery managers for regulating the mesh sizes to determine the minimum mesh sizes of target fish species.en_US
