ON THE DESIGN OPERATION AND EFFICIENCY OF IIM DUAL PURPOSE TRAWL FOR SAMLL MACHANISED BOATS

Abstract

Preliminary midwatcr fishing trials were conducted off Cochin
with a 11 m. dual purpose trawl during the monsoon months
when the prawns were available in the column layers. Further,
with a view to assess its suitability as bottom trawl, the gear
with suitable modifications in the rigging was towed in comparison
with a 15m. bottom trawl along the depth ranges of 5-10 m.
and 10-20 m. and the fishing operations were found satisfactory
