Abstract

The blue spot mullet Valamugil seheli spawns once a year between August
and February with peak spawning during October· November. Males attain
maturity at 250.5 mm and females at 256.5 mm total length. Males
outnumbered females in the commercial catches, although the sex-ratio (M:
F = 1:0.90) in the population showed no significant deviation. The fecundity
of this species varied from 108378 to 910350 eggs with an average of 327944.
Linear relationships were found between fish length, gonad weight and
fecundity; and between fish length, fish weight and ovary weight.
Keywords : spawning size at first maturity, sex ratio, fecundity
