摘要：In the lower Guadiana basin (southern Iberia) there was a significant change in the summer relative abundance of fish species-size combinations from 1994 (low discharge) to 1996 (high discharge). Notable increases were observed in the smaller size classes of repohilic cyprinids (Barbus spp. and Chondrostoma willkommi), but most species, particularly small sizes, presented increased catches.
