Abstract

The ichthyofauna of River Dinder flood plains consisted of (31) species belonging to 20 genera and 13 families representing about 14.4% of the total number of fish species occurring in the River Nile and its tributaries in Sudan. The catch was dominated by species belonging to the families Clariidae, Characidae, Cichlidae, Bagridae, Distichodontidae and Osteoglossidae respectively. Ras Amir ‘mayah’, the largest water body in the flood plains, contained the most diversified fish fauna among the six sampled stations with a total number of 21 species. Birkat El Orta pool ranked second (13 species), followed by Ain El Shamis ‘mayah’ (10 species), then Al Tabia pool (9 species), Greirisa ‘mayah’ (5 species) and finally Birkat El Timsah pool with only 4 species. The highest mean catch per unit effort (CPUE) was obtained for Birkat El Timsah pool with a mean value of 2233 kg/100m2/ day. Mean CPUE values of 152, 62, 35, 26 and 24 kg/100m2/day were recorded for El Tabia pool, Greirisa ‘mayah’, Ain El Shamis ‘mayah’, Ras Amir ‘mayah’ and Birkat El Orta pool respectively.


Key words: Catch per unit effort, Flood plains, Ichthyobiomass, ichthyofauna, index of evenness, Index of relative importance
