Standard length ranged between 11.5-24 cm, and total weight ranged 35-180 g. Their main food was detritus (32.54, 99.15, 28.12) according to the Points(P), Frequency of Occurrence(O) and Index of Relative Importance (IRI) methods respectively. Secondly phytoplankton (25.13, 95.79, 22.48), respectively. In the Third place Diatoms.  Food items included Aquatic planets and their seeds, zooplankton, sand, and other foods materials were also found. It was recorded that the higher feeding amplitude in Winter season ( 22.65  point \ fish ) and the lower feeding amplitude was recorded in  Autumn   (46.66%  point \ fish ).
