Fish were sampled by electrofishing at three contiguous sites 26 km from the source of Oued Sebaou, a seasonal river in North Algeria. River discharge ranges from 300 m 3 s −1 in the peak of the rainy season to 0.1 m 3 s −1 at the end of the dry season. Extensive gravel extraction from the river bed takes place during the dry season. Two species were recorded at each site: Barbus callensis , which is heavily fished locally, and Anguilla anguilla . The three sample maximum likelihood Zippin method was used to estimate mean density and standing crops, which were: barbel, 452 fish ha −1 , 5.33 kg ha −1 ; eels, 149 fish ha −1 , 3.04 kg ha −1 . Estimated average biomass and production were: barbel, 2.31 kg ha −1 , 4.27 kg ha −1 year −1 ; eels, 1.51 kg ha −1 , 2.60 kg ha −1 year −1 .
