Some morphometric traits of Rita rita from Southern Punjab, Pakistan

In this research work, forty five (45) specimens of Rita rita inhabiting River Chenab, one of the five rivers of the Punjab Province, were evaluated to observe morphometric and proximate composition of the fish specimens. To analyze the influence of biological factors, condition factor was determined based on body constituents using regression equations. Various morphometric characters i.e. total length (TL), standard length (SL), fork length (FL), 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), dorsal fin base (DFB), anal fin base (AFB), caudal fin length (CFL), and caudal fin width (CFW) were measured to know their correlation with the size and types of growth pattern. Morphometric analysis showed isometric growth pattern of the fish in the current study.
