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