Abstract
Design details of the commercial trawls operated
along Andhra Pradesh coast during 2006-2008 are
presented. The trawls in Andhra Pradesh are
broadly classified into three types based on the
target groups, viz., fish trawls targeted for finfish,
shrimp trawls for shell fish and cephalopod trawls
for exploitation of cuttle fish and squid. This
classification shows that the industry has developed
into a target fishing sector using resource specific
gear. Shrimp trawls have undergone several changes
in the course of time with increase in the number
of seams from two to six, increase in vertical height
and also increase in the length of the net. Mesh size
in fish trawls in the fore part of the net increased
from 150 to 2000 mm to reduce the drag. Two seam
fish trawls, with head rope ranging from 20 to 81
m are widely used for exploitation of finfish in
Andhra Pradesh. The codend mesh size of all the
trawls were less than those stipulated in the Andhra
Pradesh Marine Fishing Regulation Act 1995.
