Four species from Pagellus genus lives in natural habitat in Dardanelles: Pagellus acarne (axillary seabream), Pagellus erythrinus (common pandora), Pagellus bellottii (red pandora) and Pagellus bogaraveo (blackspot sea bream), and also these have economic importance. For these reason, we are working for produce of axillary seabream on culture condition.

Axillary seabream catches with longlines from approximately 40 m deep of Dardanelles, average 25.8±1.93 g weigh totally 800 axillary seabream, that had been transferred at the research and extension center of Fisheries Faculty at Çanakkale Onsekiz Mart University were used for the experiment. Fish were stocked in 750 L circular fiberglass tanks (80 fish per tank) with a 100 L min-1 filtered free flow sea water system. Dissolved oxygen, pH, temperature, salinity and conductivity of the water were 7.2±0.6 mg L-1, 7.67±0.22, 19±2 °C, 28±1 ppt and 29.94±1.04 μS cm-1, respectively. The fish were fed twice daily mid-morning and mid-afternoon to apparent satiation with the preparing 2 mm new diet.

Proximate analyses of the diet were given Table 1. Growth parameters were given Table 2 at 270 days.

At the end of growth period, fatty acid analyses were carried out on dorsal muscle of the axillary seabream.
