| Due to study the food regime of Arius dussumieri, a total of 132 specimens were collected
from Oman sea waters, Sistine & Baluchistan province. The stomach content, were taken into
consideration and it was found that the amount of full, semi-full and empty stomachs were 31,
33 and 36 percent, respectively of which the highest frequency was in winter (74%) and the
lowest was in summer (24%). On the other hand, the fullness index was studied with the
highest and lowest value for spring (44%) and winter (5%), respectively. The GaSI shows
that A.dussumieri, has better feeding in spring and summer but feeding (up in male) was
decreased in autumn and winter. The Food Preference (FP) Index was estimated as: Fishes
(39%), Crustacean (40%) and Molluscs (20%) namely all of them are considered as minor
food in all four seasons. The most important food items were identification as fishes:
Carangidae, Engraulidae & Leiognathidae crabs: Portunidae & Porcellanidae shrimp:
Alpheidae cephalopods: Loliginidae & Opisthoteuthidae gastropods: Muricidae & Naticidae. |
