The reproductive biology of Algerian barb, Luciobarbus callensis (Valenciennes, 1842) in Beni Haroun Dam (North-east of Algeria) was studied. A total of 303 fish samples (251 females and 52 males) from catches of local fishermen, were collected monthly from February 2015 to January 2016. The total length of the fishes is ranged from 16 to 47 cm. The spawning period was determined by analyzing the monthly evolution of the gonado-somatic index (GSI). The liver somatic index (LSI) and the condition factor (Kc) were calculated, and the corresponding curves were fitted. The sexes of specimens were determined macroscopically and the observed sex ratio was in favor of females during the whole cycle of study. The monthly monitoring of the gonado-somatic index (GSI) reveals that the spawning period is extended from April to June, within which LSI decreases when GSI goes up. This can be explained by the use of the liver reserves for the gonad developments.
Key words: spawning period, gonado-somatic index (GSI), liver-somatic index (LSI), condition factor (K), sex ratio.
