| Stomach Contents Of Some Economic Bony Fish (Teleostei) Species In The Sea Of Marmara
In this sdudy was carried out in order to determine feeding behaviour of the species Merluccius merluccius (Linnaeus,1758), Merlangius merlangus (Linnaeus,1758), Pomatomus saltatrix (Linnaeus,1766), Mullus surmuletus (Linnaeus, 1758) ve Sarda sarda (Bloch, 1793) fished the sea of Marmara
Firstly the length and the weight of the samples were designated. After being dissected and weighed its fullness values were recorded. Stomach content scattered into a petri dish and the percentage of food category was designated. Study stomach content has been kept in 5 % formol solution. Organisms in the stomachs were identified to the lowest taxonomic level possible.
The diet of Merluccius merluccius was mainly composed of fishes, benthic crustaceans and cephalopods. In contrast small hakes was generalist the adults were more specialised and their diet was mainly composed of fishes were determined.
The main diet of Merlangius merlangus was composed fishes, benthic crustaceans and polychaetes
Being investigated on the other species is Pomatomus saltatrix showing clear ontogenic changes. In contrast the diet of small bluefish was composed benthic crustaceans, the adults (>40 cm) were completely piscivorous.
In analysis the stomach of Mullus surmuletus, this species was generalist every age so they exploited a wider range of resources.
In the last of result section the diet of Sarda sarda was mainly composed fishes were mentioned.
The result obtained from the analyse in this study are given with graphics, compared with other studies. In the last section there is an idea about the study.
