Abstract

The length-weight relationship in O.cuvieri and J.glaucus can be described
by the equations log W = -5.27997 + 3.13225 log L and log W = -4.93431 + 3.02556
logL respectively. The length at first maturity in O.cuvieri is estimated as 256
mm and in J.glaucus as 180 mm. Empty stomachs occurred in high percentage
in both the species. A study on composition of food items revealed that
O.cuvieri feeds on a variety of organisms while J. glaucus a selective feeder.
Key words : Length-weight relationship, food & feeding, maturation,
spawning.
