ABSTRACT

To study length-weight relationship (LWR) and length-length relationships (LLRs) of farmed Catla catla, thirty fish specimens were collected from a fish farm located at Muzaffargarh, Pakistan during January, 2019. Total length (TL), standard length (SL), fork length (FL) and body weight was taken of each fish specimen. Mean TL and body weight (W) of studied fish specimens of C. catla was found 49.14±1.58 cm and 1775.29±191.18 g, respectively. Results of regression analyses revealed highly significant (P < 0.001) correlation for LWR and LLRs in farmed C. catla. Value of exponent b was found 3.23 in LWR of farmed C. catla indicating positive allometric pattern of growth in C. catla. While, in LLRs, b-value was observed 1.00 or close to 1.00, indicating isometric pattern of growth in SL and FL with an increase in TL for the studied fish species. Mean condition factor value was found 1.49±0.04 in the present work. Results of this work will be useful for fishery biologists and fisheries management.
