폐쇄식 순환사육수조에서의 감성돔, Acanthopagrus schlegeli 치어의 적정 먹이량

Optimum feeding rate of black sea-bream, Acanthopagrus schlegeli juveniles in a closed recirculating seawater system

A growth experiment of black seabream, Acanthopagrus schlegeli, under different feed amount per body weight in the recirculating water system was conducted at the invertebrate culture laboratory of Yosu National University from March 10 to May 10, 1999. Eight culture vessels with a capacity of 55 ℓ of water each were used under the same condition of water parameters except for feeding rate which were designated to maintain at 0, 0.5, 0.7, and 1.0% per body weight. The highest growth and survival rates of A. schlegeli were obtained when they were fed on artificial 0.7% with 15% of daily growth rate and 100% of survival rate, while lowest performance on non-feeding.
