Abstract
The feeding habits of Mossul bleak, Alburnus mossulensis Heckel 1843 in Azad dam of Sanandaj province were investigated by stomach content analysis of 75 fish collected seasonally in 2015-2016. The diet consisted mainly of fish prey dominated by Bosminidae of zooplankton (50.2%), with Bosmina longirostris being the dominant prey item based on numerical percentage. The next major food group was Daphniidae (36.3%), followed by Sididae (11.3%), Cyclopidae (1.5%), Acartidae (0.7%), Nematoda (0.1%) and Testudinelidae (0.1%). Based on frequency of occurrence, B. longirostris was the main prey in the stomach of Mossul bleak (Fi =75.4%), with an important species index (ISI) of 39.5%. The fish fed on a wider variety of food items during spring than during other seasons. The lowest feeding activity (GaSI) was recorded in summer. The gastrosomatic index (GaSI) ranged from 2.67 to 4.27 with season variations increase in spring coincides closely with spawning season and energy preservation for gonadal development.
