Abstract: The Gold spotted grenadier anchovy, Coilia dussumieri Val. forms an important component of dolnet (Bag net) and trawl fishery. For morphometric analysis 63 specimens were examined and the total length was ranged between 9.2 and 16.2 cm (mean 13.34± 1.56). A total of 477 specimens (416 males and 61 females) were used for the study. The overall ratio of males to females in the population was 1: 0.15. Length-weight relationship of C. dussumieri indicates negative allometric growth and found to be significantly different at 1% level. The fish follow the cube law. The relationship between L-W of the species were fitted as Log W = - 1.85006 + 2.4090 Log L, R2 = 0.78 (combined); Log W = - 2.23497 + 2.74196 Log L, R2 = 0.86 (male) and Log W = - 0.71091 + 1.40273 Log L, R2 = 0.41 (female). A size group 12.3 to 13.9 cm. was found to be predominant (38.16%) followed by 13.9 to 15.5 cm. (36.48%) and can be optimally exploited.
