Abstract


Some biological characteristics of the fish Himri barbal, Barbus luteus (Heckel, 1843) was described in Eastern side of Hammar marsh, south of Iraq from January 2009 to May 2010. The fish represented about 2.2% of the total catch exploiting different kinds of fishing gears. Fish size of 12-19cm constituted about 72.3% of the catch size. The length-weight relationship was W = 0.0075* L3.2245 revealing an allometric growth in this fish. Six age groups were recorded and their mean total lengths were 10.5, 16.5, 20.6, 24.5, 27.5 and 29.7cm, respectively. The parameters of growth profile, namely, the asymptotic length (L∞) as well as the growth coefficient (K) were 37cm and 0.26, respectively. Food items were quantified using an index of relative importance. Results revealed that the main food items of B. luteus were from aquatic plants (22.3%), algae (19.8%), insects (13.8%), snails (12.8%) and isopods (11.4%). Values of gonado-somatic index were highest in April for females (13.90) and in March for males (7.74). Results of the present investigation suggested that the growth of this fish at the study site was fairly good and the spawning season commenced during March to April.
