Abstract
Influence of horizontal opening on the catch of different species groups, in respect of three designs of bottom trawls have been evaluated through field trials. 25 m high opening trawl was found to be most effective for catdiing ribbon fish and small miscellaneous fish at a horizontal opening of 15-16 m. For Lactarius sp.and Sciaenids, 25 m large mesh trawl was found to bemost efficient and the horizontalopening of18-20 m and 16-18 m respectively were found to be optimum for the two species groups. For squid and cuttle fish, 25.6 m BOBP high opening trawl gave better performance at a horizontal opening of 16-17 m and beyond this range, its performance was similar to that of 25 m large mesh trawl.Downloads
