| This project accomplished with aim of new studies on the type and nutritional content density, coefficient of empty stomach and detection it’s favorite food in different months of year on silver Pomfret fish. For this reason 1095 fish of this kind captured from station: Musa estuary, Bahrekan, Boshehr and Dayyer in the north-east of Persian gulf in year (2012-13), and their sampling of stomach and intestine is performed in there. Thus, the detection nutritional resources in samples includes 18 kind of food with plant source and 12 kind with animal source, that observed greatest food preference from plant sources Diploneis sp., Nitzschia sp., Rhizosolenia sp., & Ceratium sp. (totally with preference 50.37 %) and from animal sources Copepoda, Cladocera & Ostracoda (totally with preference 24.72 %) and also Peridinium sp. & Prorocentrum sp. are from plant resources (respectively 2.4 % and 3.51%) that observed accidently in their nutritional diet. Most nutrition compression occurred in the year between October and February that have mainly plant source, and amount of food with plant source decreases and increases animal source in the year between April to May (P<0.01). On the base of coefficient of filled stomach and intensive of fish, the lowest coefficient is related to May until September with average 37.05 percent and highest amount observed with a mutation in April with 79.8 percent at two years. |
