Abstract
•Length-weight relationship of mate and female L. dussumieri was found to
be different. Within femallesi, the SimirMure, maturing, mature and spent-recovering
females differ from one another in the length-weight relationship. Males weigh
comparatively less than females. Among the females, immature, maturing and spentrecovering
females weigh more than mature females. This species mainly spawns
during April>-Maiy and November-December, Minimum sfefe of maturity for males
were found to be 78 mm and for females 83 mm. Generally, females predominate
over males in the commercial catches. The counts of mature ova ranged from 805
to 41683 per female. The fecundity-length relationship has; beea studied by three
diffrent formulae and it was found that fecundity is better related; to direct cube
of length.
