Abstract

The samples were collected by using Isaac Kid-Midwater Trawl (IKMT) onboard FORV Sagar Sampada during the deep

scattering layer (DSL) survey from 1998-2000 of the eastern Arabian Sea (AS). Length-weight (LW) relationships have

been carried out for the most commonly occurring myctophid species

Benthosema pterotum of the DSL.

The LW relationship

was W = 0.00000753 L

3.13145 (r= 0.973708) for males and W = 0.000007379 L 3.13529

(r = 0.974880) for females. From the

studies it has been noticed that growth in relation to length and weight deviate appreciably from the cube law. It is also found

that there are no significant differences between males and females of the species.
