Abstract
In present study attempts has been made to document the fishing crafts and gears which operated in Thirumoorthy reservoir, Tamil Nadu. This investigation revealed, the post monsoon season had higher catch per unit effort of 11kg/boat/day by gillnet fishing and about 20 to 30kg/day in cast net. Catla catla has the dominant fish species and accounted about 58% followed by Cirrhinus mrigala (29%), Labeo rohita (12%) and Cyprinus carpio (2%) against the total landings. However, three species including the Tilapia, Rohu and Mrigala were found to constitute fishery in the cast net with mean CPUE of 20 to 30 kg per day.
Highlights
Inland fisheries have an important role which provides employment, income generation, contributing to gross domestic production
In Thirumoorthy reservoir, fishing activities has been by gillnet and cast net
The present study concluded, the fishing gear of gillnet and cast net is operating in Thirumoorthy reservoir of Tamil Nadu
Summary
Inland fisheries have an important role which provides employment, income generation, contributing to gross domestic production. The fish production was found to be higher of 48.50 kg/ha/yr in small reservoirs, followed by 13.74 kg/ha/yr in medium reservoirs and 12.66 kg/ha/yr in larger reservoirs, 22.63 kg/ha/yr in pooled[12]. This productivity varies with size of water bodies and influenced by the environmental parameters includes water, soil[9,12]. Gill net is one the major fishing gears are operating about 80 per cent in inland water bodies It is a passive gear, set gillnet is apparently the only type of fishing gear suitable for reservoir gill net fishing[5]. Carried out to provide baseline information on the operational and technical details of different fishing gears in this reservoir
