Abstract

The regression coefficients in length-weight relationship of males and
females of Tachysurus tenuispinis differ significantly. The relative condition
factor was calculated for females in relation to various lengths and months.
The sex ratio in the catch varied widely in the different months. The number
of eggs ranged from 72 to 89 for the fish of length 394 to 570 mm. Empty
stomachs occurred in a very high percentage (63.5%) of the total stomachs
examined. This is a bottom carnivorous feeder. The main food items found
in the guts in order of preference were crustaceans, polychaetes, molluscs,
fishes and echinoderms.
Keywords: Tachysurus tenuispinis, length-weight relationship, relative
condition factor, sex ratio, fecundity, food and feeding habit
