Abstract
Comparative studies with a new 17 m parallel iwin· body trawl and a 17 m bulged
belly trawl conducted off Cochin during 1974-'77 are reported. The parallel twinbody
trawl showed an increase of 28% in catch over that of bulged belly with a break
up of 39.9% and 23.1 % for prawns and fishes respectively. The increase in catch
is attributed 1D the extra wide mouth opening(26.6 %) of the parallel twin-body trawl.Parallel twin-body trawl had 8.96% lesser resistance which resulted in lower utilizationof horse power
