Abstract

The present study was carried out for estimation of growth parameters of TENUALOSA ILISHA.in Khuzestan Province using length frequency data. For this purpose 10071 specimen of Hilsa Shad were collected from fishing boats and measured during one year study (2008 to 2009). Growth parameters were estimated by ELEFAN programme of FiSAT II software. The growth parameters of von Bertalanffy equation were estimated as: L ¥: 42.8 cm and K: 0.7-1 year using automatic search of ELEFAN and 46.6 cm and 0.8-1 year using Shepherd' method. Mortality coefficients including total mortality (i.e. Z: 3.45) and natural mortality (i.e. M: 1.24) and fishing mortality (i.e.F:2.21) were estimated. EXPLOITATION RATIO (E) was estimated 0.64 and These high values of E revealed that the Hilsa Shad stock in the region is overexploited. The results of this study showed that EXPLOITATION RATIO of the Hilsa Shad stock is reaching to its maximum situation and for decreasing it, more consideration should be undertaken.
