Description The regional and seasonal distribution and abundance of threadfin breams and
lizard fish are presented as revealed by the bottom trawling operations of FORV
Sagar Sampada during cruises 56-91 (1989 and 1992). The threadfin breams
occurred in 49 and lizard fish in 25% of the total number of bottom trawhng stations
surveyed. The most productive grounds for threadfin breams were located in the
southwest coast between 8° and 15° N latitudinal zones, with the area 11775°
yielding the highest average catch rate of 1794 kg/hr. Very high congregation and
concentration of threadfin breams, composed mainly of Nemipterus mesoprion and
N. japonicus, was observed in the southwest in 41- 80 m depth zones during
southwest monsoon period. Lizard fish resources, composed mainly of Saurida
tumbil and S. undosquamis were also relatively more dominant in the southwest
coast than along the east coast and in the EEZ of Andaman-Nicobar islands. The size
distribution of N. japonicus and A', mesoprion showed that smaller modal groups
were dominant in shallower depth zones. The potential yield of threadfin breams in
the southwest zone was estimated to be 2.05 x 10 .
