| Abstract: | Nemipterus
japonicus
specimens collected from Mumbai, Ratnagiri and Panaji showed positive and high
degree of correlation (P<0.01) in between various morphometrics. Pooled
regression equation for Mumbai, Ratnagiri and Panaji established between fork
length and total length was FL = 0.2404 + 0.8912 TL, while estimated equation
of standard length on total length was SL = 0.1866 + 0.7736 TL. Established
regression equations for head length on total length and head length on
standard length were HL = - 0.1102 + 0.2465 TL and HL = - 0.1641 + 0.3181 SL
respectively. Weight on total length relationships for Mumbai, Ratnagiri and
Panaji specimens did not differ significantly, therefore, data was pooled and
estimated regression equation was W = 0.0141 TL 3.0103, wherein
isometric growth was observed. There were no significant differences observed
between the relationships established among the morphometric characters as well
as among length-weight relationships of N.
japonicus collected from Mumbai, Ratnagiri and Panaji. The above envisages that fish which landed at all the three
localities belonged to a single stock. |
