Some population dynamics aspect of Catla catla (Hamilton) in the Sylhet Basin, Bangladesh

A. K. Yousuf Haroon

Abstract: Population parameters of Catla catla (Hamilton) were estimated using FiSAT software with length-frequency data collected from different areas of Sylhet basin, north-eastern part of Bangladesh. The von Bertalanffy growth parameters L∞ and K for the species were 93.95 cm and 0.53/year respectively. The annual rate of natural (M) and fishing mortality (F) were found to be 0.84 and 0.85, respectively. The mean length at first capture (Lc) was estimated as 11.29 cm. The rate of exploitation (E) was estimated as 0.503. Recruitment of this species into the fishery takes place during May to July. Peak recruitment occurred during the month of May E_max was found to be 0.41. Their total length total weight relationship was found to be W = 0.012TL3.04.
