초록

EP 사료의 성장 및 사료효율, 비만도 등 사육 성적에 대한 평가가 MP 사료와 견줄만한 성장 결과를 도출하는 것으로 확인하였으며, 배합사료만으로도 충분한 성장이 가능하여 산업화 보급에 전혀 손색이 없을 것으로 판단된다. 또한 EP사료가 면역 증강 및 질병 억제에 긍정적으로 영향을 미칠 것을 사료되며, 현장시험을 통해 질병의 유병과 분포에 대한 자료가 현재의 양식집단을 진단하고 질병의 원인 및 위험인자 규명, 질병 예방 및 집단의 건강관리 대책 수립에 중요한 역할을 할 것으로 기대된다.

영어초록

This study was conducted to effect of extruded pellets (EPs) and moist pellet (MP) diet on growth and fish health parameters in farm cultured olive flounder Paralichthys olivaceus. Two replicate groups of 2,600 fish per each tank (initial weight of 30.1±0.2 g) were fed one of the three EPs (EP1, EP2 and CEP) and one MP for 13 months.
In field feeding experiment conducted in commercial flounder farm, survival, growth (30-600 g) and condition factor of fish fed experimental EP1 and EP2 were comparable to those of fish fed MP, but considerably higher feed efficiency and protein efficiency ratio were observed in fish fed experimental EPs. Viable cell counts from diet and water from MP diet were considerably higher than those from EP diet, and lysozyme activity from EP diet was higher than that from MP diet. GOT and GPT of fish fed the EP diet were considerably lower than those from MP group, but total protein and glucose concentration of fish fed the EP groups were not significantly different from that of fish fed the MP. Therefore, these results strongly suggest that EP diets could be developed to replace MP diet without adverse effects on growth performance and to enhance the immunity and protective ability of olive flounder against fish disease such as Vibro, Edwardsiella and Strptococcus.
