Description Bottom trawling data from the cruises of the FORV Sagar Sampada undertaken
during 1989-91 in the middle and outer shelf waters of the southern EEZ, at 97
stations within a depth zone of 30 to 130 m, showed catch rates of 3 to 14000 kg/hr.
The highest rate of 14 t/hr was recorded at lat. 1 l°N/75° 23.4' E, followed by 5.5t/hr
at 8°54'N N/76° 19.6' E off the southwest coast, whereas the abundance was
comparatively less off the southeast coast. The average catch rate per hour off the
southwest was 724 kg and off the southeast it was 405 kg. The important demersal
finfishes available were: threadfin breams (72%), major perches (5%), rays,
carangids and goatfish (4% each) off the southwest; and carangids (29%), major
perches (23%), rays (19%), threadfin breams (10%) and goatfish (5%) off the
southeast. The depth belt of 41-80 m off both the coasts was found to be more
productive than deeper regions. The results indicate that the potential yield from the
depth zone of 50-100 m off the southwest coast is 2.6 x 10 tonne, which is much
higher than the previous estimates of up to 1.5 x 10 tonne. The single largest group
(80%) in this zone is threadfin breams, followed by bull's eye, lizard fishes and
flatheads.
