    Summertime diel variations in the diet composition and feeding periodicity of red pandora (Pagellus erythrinus) in Hisaronu Bay
    (Cambridge Univ Press, 2001) Benli, HA; Kaya, M; Unluoglu, A; Katagan, T; Cihangir, B
    In summer 1997, the stomach contents of 235 red pandora collected by bottom trawl from Hisaronu Bay in the southern Aegean coast of Turkey, were analysed. It was observed that red pandora is predominantly a diurnal feeder. More intensive feeding started in the afternoon, reaching its maximum value in the evening and continued until dusk. The minimum feeding intensity occurred during the night. The diet was found to consist primarily of polychaetes, especially Glyceridae, and crustaceans, mainly Natantia. No significant diel variation was observed in the diet composition of red pandora.

    Variations in the feeding intensity and diet composition of red mullet (Mullus barbatus) during 24-h period in the summertime in Hisaronu Bay
    (Cambridge Univ Press, 2002) Unluoglu, A; Cihangir, B; Kaya, M; Benli, HA; Katagan, T
    Diet Feeding pattern of red mullet in the Hisaronu Bay was studied from samples collected by bottom travel during a 24-h period in the summer of 1997. Feeding activity of red mullet commenced at dawn and reached its maximum value at noon. During the period between noon to early evening, feeding intensity showed clown and then showed a small increase towards sunset. After sunset, the feeding activity nearly stopped and fish with empty stomachs increased. At night almost all stomachs were empty. Polychaetes, decapods, bivalves, and amphipods were the major prey groups in the diet of red mullet and no significant diel variations were observed in the relative importance of these groups.
