Abstract

Tuna and tuna-like fishes are under-exploited resources of Indian EEZ. Exploitation of oceanic tuna and billfishes are possible only by longlining and purse seining. Existing deep sea fishing vessels in India are mostly trawlers equipped for bottom trawling for shrimps and fishes. Most of them are stem trawlers and few are double riggers. Hence the deck layout is not suitable for either longlining or purse seining. Both longlining and purse seining for oceanic tuna and billfishes are specialized techniques which require special onboard facilities, deck layout and deck machineries like line haulers, chute, shooting and hauling accessories for longlining and special powerful purse winch, power block etc. for tuna piu'se seining.
