Investigation on feeding tables for sea bass (Dicentrarchus labrax L., 1758) in net-cage (Pinar Marine Company) culture

Hossu B., Korkut A.Y., Salnur S.

Although feed manufacturers provide feeding tables for marine fish according to water temperature, these should be tested under local conditions. A feeding table proposal was tested for ad libitum feeding of sea bass in a cage farm. Fingerlings were divided into 3 groups (1.83 g, 1.80 g and 1.87 g) and were stocked in 5ž5ž5 m net cages. They were transferred later on to 7.5ž7.5ž7.5 m cages, then to cages of 12 m in diameter at a depth of 10 m, and finally to 20 m diameter cages at a depth of 15 m. Fish were fed on type-2 granule feed at the beginning and on type-4 pellets (12 percent max. moisture, 45 percent min. crude protein, 12 percent crude oil, and 3536 kcal/kg of digestible energy) at the end of the feeding period. Fish were checked monthly, and growing rate, feed conversion rate and fish mortality were studied.
