Morphometry, LW relationship, L. subviridis, L. parsia, mullet


A total of 638 specimens of Liza subviridis and 664 specimens of Liza parsia were collected from Ganjam coast, Odisha and were used for length-weight, morphometry and meristic analysis. Correlation and regression analysis was carried out for 26 morphometric and 10 meristic characters in relation to total length (TL). In length weight-relationship calculation for L. subviridis, the b value was found to be 2.993 for male, 2.986 for female and 2.976 for pooled sex. Similarly, for L. parsia, the b value was found to be 2.791 for male, 2.846 for female and 2.820 for pooled sex. Statistical analysis (t-test) indicated that L. subviridis showed isometric growth while L. parsia showed negative allometric growth. However, no significant difference in b value was observed between the sexes of both the species at 1% and 5% level (P>0.05). Deviation in b value observed during the present investigation from that of other countries and different
regions in India is due to variation in ecology of these geographical locations. Results indicated that the relationship between TL and most of the morphometric characters is strong (R2>0.7) and highly significant for both the species. Though significant variation were
observed in some of the morphometric characters such as head length (HL), snout length (SnL), body depth (BD) and depth of caudal peduncle (CPd) for L. subviridis and eye diameter (ED), pre dorsal length (PDL), distance between two dorsal fins (SI) and first dorsal spine length (D1S1L) for L. parsia, most of the morphometric characters remain insignificant (P>0.05), hence it is difficult to differentiate the male and female individual of same species morphologically. From the present study it is clear that study of morphometry not only important in systematics but also these are valuable in observing the phenotypic variations among the male and female individuals of same species.
