ABSTRACT

Various morphometric characters i.e. total length (TL) standard length (SL), head length (HL), head width (HW), body girth (BG), body depth (BD), Dorsal fin length (DFL), pectoral fin length (PtFL), pelvic fin length (PvFL), anal fin length (AFL), eye diameter (ED), caudal fin length (CFL), caudal fin width (CFW) of farmed collected Ctenopharyngodonidella were studied to know their correlation with reference to size (TL and W), and types of growth pattern. Correlation coefficient (r) value (0.984) shows high significant relationship between total length and wet body weight, while growth pattern was isometric as value of ‘b’ being 2.97 (95% confidence interval of b = 2.840 to 3.092) was very close to ideal slope value (b = 3). Highly significant correlationships (P < 0.001) were found between body weight versus various morphometric characters. The interrelationship of total length to SL, HL, HW, BG, BD, HW, BG, BD, DFL, PtFL, PvFL, AFL, ED, CFL and CFW were highly significant (P < 0.001).
