| description | The immigrant S. commerson (Lac., 1802) represents more than 2% of the total Egyptian catch and its distribution stretches from East to West along the Egyptian Mediterranean coast. The feeding habits of T. lepturus and S. commerson were investigated through stomach content analysis of specimens collected from Abu Qir Bay (Egypt) on a seasonal basis from November 1999 to January 2001 using daytime purse seines. The food content range of T. lepturus was wide, including Engraulis encrasicolus, Gobius spp., Sardinella aurita, Sardina pilchardus, fish eggs, amphipods, copepods and shrimps. The main diet constituents of S. commerson included Engraulis encrasicolus, Sardinella aurita, Sardina pilchardus and shrimps. Seasonal variations of feeding activity indicated that food consumption was highest in spring to autumn for T. lepturus and in summer and autumn for S. commerson. The diet overlap in terms of number and weight between the two species was high. Food composition was related to fish size in both examined fishes. Small T. lepturus (less than 30 cm) fed mainly on crustaceans, while larger samples (more than 59 cm) fed only on fishes. Teleosts were the most important food item for S. commerson of all sizes, while this species became piscivorous when larger than 40 cm in length. |
