Abstract

The parameters of the length-weight relationship of the form W = aLb are presented for 215 males, 277 females and 119 indeterminists with size range 6.4 to 29.9 cm TL. Samples from commercial (purse seines, Rampani, trawl, gill nets) and artisanal gears were taken during March 2011 to February 2012. From the F - ratio, it is evident that there is no significant difference among the regression coefficients between male, female and indeterminate. The estimated “b” values indicated positive allometric growth in males females, indeterminate and total (P < 0.05).
