Abstract

The length-weight relationship in 0.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 0.cuuieri 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.cuuiei-i feeds on a variety of organisms while J. glaucus a selective feeder. Key words : Length-weight relationship, food & feeding, maturation, spawning.
