Abstract
The length-weight relationship of Priacanthus hamrur inhabiting the continental slopes
beyond 300m along the west coast of India was estimated. The length-weight relationship
was analyzed using the formulae W= a Lb which was further logarithmically transformed
into Ln W=Ln a+b Log L. A total of 295 fishes comprising of 105 females and 190 males
with size groups ranging from 196 to 297mm(TL) were used. The length-weight relationship
of P. hamrur can be represented by the equations. Females W=0.0097 L305 and Males W=0.025
L2 73. While comparing the 'b' values of male, female and combined P.hamrur, it was
understood that there was no significant difference among them. The value of the exponent
'b' computed in the parabolic equation for females did not show much variation for the
isometric value of 3 whereas the value of b in males was found to be less indicating a very
slight negative allometric growth. This was also reflected on the length-weight relationship
of the combined population of P. hamrur.
