We ran a feeding trial to determine optimal dietary protein and lipid levels for growth of juvenile long snout bullhead Leiocassis longirostris Gunther. Eight experimental diets (P20L7, P20L14, P30L7, P30L14, P40L7, P40L14, P50L7 and P50L14) were formulated to contain 20%, 30%, 40% or 50% protein co...

종어란? | 종어(Leiocassis longirostris Gunther)는 메기목 동자개과 종어속에 속하는 담수어류로서 최근에 중국을 비롯하여 한국에서도 고급 양식 대상종으로 잠재력이 높은 종이다(Pei et al., 2004). | |
종어속에 속하는 종어가 섭취하는 먹이 생물은? | , 2004). 종어는 육식성으로 소형 어류나 저서 갑각류를 섭취하는 것으로 보고되어 있다(Xie et al., 1998). | |
어류의 성장에 가장 큰 영향을 미치는필수 영양소는 무엇인가? | 어류가 활동하고 성장하기 위해서는 수십 가지의 필수 영양소와 에너지가 필요한데, 이 중에서도 단백질은 어류의 성장에 가장 큰 영향을 미치는 필수 영양소이다. 또한, 사료의 영양 성분 중 단백질 함량이 차지하는 비율이 매우 높고, 사료에 배합되는 단백질원의 가격이 비싸기 때문에, 양식 대상어종의 적정 사료단백질 함량을 구명하는 것은 경제적인 배합사료 개발에 필수 적이다. |
