Length-Weight relationship of mature Hilsa, Tenualosa ilisha in Bangladesh

An experiment was carried out to determine the length, weight, and Length-Weight Relationship of mature hilsa, Tenualosa ilisha, in Bangladesh better manage fish species. Total 480 Samples were collected from Meghna River, Chandpur, July 2012 June 2013 Tentulia Barisal, 2014. length (TL) measured using a measuring scale, body weight (BW) taken an electric balance. Length-weight relationship (LWR) relative condition factor (Kn) fishes determined. In case female hilsa mean TL value varied 37.21±0.81 42.58±0.80 cm, for male, 34.25±0.55 37.03±0.75. For found vary 37.48±0.90 41.18±0.78 males, 34.80±0.69 37.19±0.59 cm. 762 ± 88.36 987.00 113.07 g, 453.60±19.25 g 626.00 18.02 g. 639.50 0.71g 992.00±61.93g, 523.00±35.96 598.00 31.26 The highest Kn recorded October (1.0688), lowest May (0.8607), male observed November (1.0197), but (0.9974) Chandpur. April (1.0895), December (0.9023). (1.032), (0.9988) Barisal.
