Pangasius is a yellow tail catfish belonging to the family Pangasiidae which is widely distributed in Bangladesh, Java, Myanmar, India, Vietnam, Thailand, and Pakistan. This species is ideal for human consumption due to its good taste and tender flesh. In the current study, 77 samples of P.pangasius of different body sizes, with ranges from 10 to 19cm were collected from Ada Band Bosan Multan Punjab, Pakistan.  Samples were used to examine the length-weight relationship among them. To address the parameters, condition factor, and their relations with respect to different morphometric characters such as total length (TL), standard length (SL), head length (HL), body girth (BG), body depth (BD), fork length (FL), dorsal fin length (DFL), dorsal fin base (DFB), pelvic fin length (PvFL), pelvic fin base (PvFB), pectoral fin length (PtFL), pectoral fin base (PtFB), anal fin length (AFL), anal fin base (AFB), caudal fin length (CFL) and eye diameter (ED) were determined. Results showed an extremely significant correlation amongst those parameters, regarding the increase in body weight and total length. Moreover, the ‘b' value recorded for the coefficient of regression was 3.12, indicating a positive allometric growth in fish. The present study aimed to sum up the available information on different aspects of P. pangasius fish of different variants, which would improve body weight for commercial growth and fish breeding.
