Survey of Feeding Diet of Bigeye Croaker (Pennahia anea) in the Oman Sea Waters

The feeding habit of Pennahia anea was studied in the north-west of Oman Sea by collecting 188 specimens during years 2010-2011. The samples were collected seasonally with midwater trawls during lantern fish fishing. Vacuity Index (VI), Fullness Index (FI), Gastro-Somatic Index (GaSI) and frequency percentage of different food items were also studied. Of total stomachs, 40 stomachs were full or semi-full and the other 148 were empty. GaSI Index average was 1.1 for the total year. The mean Vacuity Index was calculated 78.7% and amount of Food Preference Index were estimated as: Fishes (92.5%), Crustacean (22.5%) and Molluscs (5.0%). b= 3.12 shows isometric growth in the P. anea. It was concluded that P. anea is a relatively abstemious species and its main food was Fishes and minor foods was Crustacean.
