| Article Name : | | | BIOMETRIC & FECUNDITY STUDIES OF HARPODON NEHEREUS (HAM-BUCH) FROM COASTAL WATERS OF MUMBAI | | Author Name : | | | Hitesh U. Shingadia | | Publisher : | | | Ashok Yakkaldevi | | Article Series No. : | | | ROR-767 | | Article : | |  | Author Profile | | Abstract : | | | A curvilinear relationship with the length that becomes linear on logarithmic transformation was observed during present investigation in Harpodon nehereus (Ham-Buch). The coefficient of correlation r=0.899 for males & r=0.951 for females signify high degree of association between the two variables. The high value of positive correlation between length & weight for both the sexes revealed that applicability of equation derived is high. Exponential value for both male & female fish is less than 3 indicate that the growth is isometric. The relative condition factor is a measure indicating the condition of fish during different seasons & stages of growth. The study indicated inter-seasonal variation by change of weight in relation to length of the test fish. The values of Kn clearly demarcates two spawning seasons during one year, first from March to July & the second from September to November that is confirmed by the study of ova diameter measurements of egg of various stages of maturity reveal that fish spawns twice in a breeding season, which is evidenced by the presence of double mature stock of ova in the ripe stage in the ovary twice In a year. The relationship between fecundity & body weight was observed to be linear in the present investigation. Exponential values of fecundity-fish length & fecundity-fish weight showed that fecundity was related more to length than to weight of the fish. | | Keywords : | | - Fecundity,Fecundity
