Abstract

Biology of Acetes indicus was investigated from coastal waters of Bombay during January 1981 to March 1983. Total length of males and females ranged between 8-25 and 8-36 mm respectively, exhibiting growth rates of 6.02 and 5.83 mm per month. The lifespan of the species was 4-6 months. The lengthweight relationship was LogW=1.9925 + 2.9698 LogL for the males and females together. The relationship between total length and carapace length was calculated as C = 0.3828 + 0.2185L. The species subsists mainly on detritus and planktonic organisms by filter feeding mechanism. The size at first maturity was 14-15 mm for males and 17 mm for females. It breeds throughout the year with peak during September- January period. The sex ratio exhibited dominance of males until 20-21 mm size and females thereafter. Fecundity has been estimated to be 4,333-10,300 for females in the size range 19-33 mm.
