Abstract

This study was conducted to evaluate extruded pellet for the growth of grower Korean rockfish Sebastes schlegeli. Two replicate groups of 150 fish per each tank(initial mean weight 112 g) were fed one of four experimental extruded pellets for 8 months. Survival was 100% in all groups. Final mean weight, feed efficiency and protein efficiency ratio, feed intake and hepatosomatic index were not significantly different among all groups. Proximate compositions of the whole body and liver were not significantly different among all groups. It can be concluded that the dietary formulation used in four extruded pellets could be applied in the practical extruded pellet for grower Korean rockfish.

본 연구에서는 육성기 조피볼락 사육용으로 부상배합사료의 효과를 조사하기 위하여 평균 체중 112 g의 조피볼락을 8개월간 사육하였다. 실험사료로 4종류의 부상배합사료를 준비하여 1일 1회 만복으로 공급하였다. 사육실험 결과, 생존률은 모든 실험구에서 100%로 양호하였다. 성장률, 사료효율, 단백질효율, 사료섭취율 및 간중량지수 모두 각 실험구간에 유의한 차이가 없었다. 사육실험 종료시, 전어체와 간의 일반성분도 모든 실험구간에 차이가 없었다. 이상의 결과로 볼 때, 본 연구에 사용된 실험사료 조성은 육성기 조피볼락 양식을 위한 실용사료의 조성으로 사용하여도 좋을 것으로 판단된다.
