Abstract

A 10-week feeding trial was conducted to investigate the effects of feeding rate on growth and body composition of adult flounder during the summer season. Three replicated groups of the fish (initial mean weight of $535{\pm}4.1\;g$) were hand-fed a extruded diet twice a day at the different feeding rates of satiation (100%), 90%, 80% and 70% of satiation for 10 weeks. Mean Water temperature was $19.2{\pm}2.8^{\circ}C$ during the feeding trial. Weight gain and condition factor increased significantly with increase in daily feeding rate (P<0.05), but there was no significant difference in weight gain of fish fed the diet between 100% and 90% of satiation. Survival and feed efficiency were not significantly different among all groups. Proximate composition of dorsal muscle was not significantly affected by feeding rate. Based on the results of this study, optimum feeding rate for growth and condition factor of adult flounder (535-928 g) seemed to be 90% of satiation.

본 연구는 사료급이율이 여름철에 사육된 넙치 성어의 성장 및 체조성에 미치는 영향을 조사하고자 수행되었다. 최초 평균체중 535g의 실험어를 12개 수조(1.8톤)에 15마리씩 사료급이율 별 3반복으로 수용하여, 1일 2회 실험사료를 급이하며 10주간 사육하였다. 사료급이율은 만복(100%), 만복의 90%, 80%, 70%(어체중에 대한 일일 사료섭취율 기준)로 설정하였다. 사육기간 동안의 평균수온은 $19.2{\pm}2.8^{\circ}C$였다. 사육실험 후, 증체율, 일일사료섭취율 및 비만도는 사료급이율에 따라 유의한 차이를 보였으나, 생존률 및 사료효율은 모든 실험구간에 차이가 없었다. 증체율과 어체의 비만도는 일일 사료급이율이 증가함에 따라 증가하였으며, 만복의 90% 급이구는 만복 급이구와 유의한 차이가 없었으나, 80% 및 70% 급이구는 만복 급이구에 비하여 낮은 결과를 보였다. 실험 종료시, 실험어의 등근육과 간의 일반성분은 실험구간에 특별한 변화경향을 보이지 않았다. 본 연구의 증체율 및 비만도 결과로 볼 때, 여름철에 넙치 성어(535-928 g)의 적정 성장 및 비만도 유지를 위해서는 만복의 90%로 사료를 급이 하여도 좋을 것으로 판단된다.
