Length-Weight Relationship and Relative Condition Factor of Coilia Dussumieri (Cuv. & Val.) from Neretic Waters off the Mumbai Coast
Hitesh U. Shingadia
Abstract: Morphometric studies are essential to determine the growth form and growth rate of a species; which is very much important for proper exploitation and management of the population of a species. The length-weight relationship & relative condition factor were computed for the Anchovy Coilia dussumieri (Cuv. & Val. ). A total of 154 individuals (124 males & 30 females) were used for the study. The b value shows significant correlation between length & weight of fish. The values obtained for mean weight by sex show that females were significantly (P<0.05) larger than males. The relative condition factor showed seasonal variation in both the sexes. Observation also suggests that female fish are generally better conditioned than the male fish. The lowest condition factor signifies that the fish is in breeding season with higher body weight. Hence fishing operations should be suspended during this period to have recruits for the next fishing season. The regression equation of wild Coilia dussumieri showed symmetrical growth in relation to body form. Thus the weight-length relationship is an useful tool in fish biology; physiology; ecology and stock assessment.
