Feeding of Saurida tumbil in the Oman Sea Waters

In order to study the nutritional behavior of Saurida tumbil in the Oman Sea (Sistan & Baluchistan province), a total of 116 specimens were seasonally collected, of which 77 specimens were males and 39 specimens were female. The minimum and maximum length of males was respectively 22.8 and 45.5 cm and for females there were 25.5 and 53.4 percent. The results showed that by increasing TL, the weight of stomach will increase too. In this study, the kind of food, some factors such as frequency percentage, Vacuity Index, Gastromatic Index of different food items were calculated. Also, results showed that Saurida tumbil has the Carnivorous diet and feeds on e.g Upeneus sulphureas, Trichiurus lepturus, Nemipterus japonicas, Platycephalus indicus, Leiognathus bindus, Sardinella sp. Tylosurus corcodilu, Sphyraena putnamie, shrimp postlarve, Sepia pharaonis and Uroteuthis duvauceli The measurement of (FP) Index expressed that Upeneus sulphureas and Trichiurus lepturus respectively by (FP) 29.6 and 12.9 percent are the seconds and main foods.Cephalopoda, Crustacea and other species are random hunts. Saurida tumbil doesn’t have any target food and hunts its foods according to the availability of existence nutrition species. Vacuity index was obtained 51.7% and it was recognized by the explanation of (CV) so this aquatic animal has the medium nutrition. The maximum Index of (FI) 93.7 percent occurred in winter and the minimum 36.8% occured in summer.
