Abstract: (9160 Views)
Based on the gut content analysis of 278 specimens of brown trout, Salmo trutta, in the Lar Reservoir and its basin, including streams of Delichay, Ab Sefid, Elarm, Lar and Siah Plas, the summer food habits were found to be general and depended on the abundance of preys. Considering the “index of relative importance” in all stations, the most consumed prey items in the streams were Diptera larva, Ephemeroptera and Trichoptera nymphs, while Hymenoptera constituted the main prey in the reservoir. It was found that the gender had no significant effect on the feeding habits of the adult brown trout.
