Abstract

The aim of this study was to record the length-weight relationship of three commercial fish in Jebel Aulia Reservoir, Sudan. This study was conducted during a period from March 2008 to February 2009 on the three main fisheries sites of Jebel Aulia dam (45 Km South of Khartoum State), El hashaba, Kosti and El nuzul. Length weight relationships (LWR) of 1269 fish population covering three commercial fish species (Lates niloticus, Linnaeus, 1758; Oreochromis niloticus, Linnaeus, 1758 and Labeo niloticus Forskål, 1775) were measured and weighted. The parameters (a) and (b) of the length-weight relationship of the form W = a Lb are presented for three fish species. The values of the exponent (b) in the length-weight relationships were (2.98-3.05) Lates niloticus, (2.76-3.07), Oreochromis niloticus and (2.54-2.71) for Labeo niloticus. The coefficient of determination (r2) was very significant for all three commercial fish species.
