쏘가리(Siniperca scherzeri) 치어 사료 내 어분대체원으로써 동애등에(Hermetia illucens)의 이용성

Abstract

A feeding trial was carried out to assess the effect of partially replacing fish meal by black soldier fly meal (BSFM) in diets for mandarin fish Siniperca scherzeri. Seven experimental groups were fed with a FM(fish meal)-based diet without BSFM (BSFM0), six diets with 5% (BSFM5), 10% (BSFM10), 15% (BSFM15), 20% (BSFM20), 25% (BSFM25) and 30% (BSFM30) of FM substitution with BSFM. Triplicate groups of fish (average weight of 6.9 g) were fed one of the seven experimental diets twice daily for 8 weeks. At the end of the feeding trial, weight gain and specific growth rate of fish fed the BSFM 30 diets were lower than those of fish fed the other diets. Feed efficiency of fish fed the BSFM0, BSFM5, BSFM10, BSFM15 and BSFM25 were higher than those of fish fed the BSFM30 diets, was not affected by BSFM20 diets. Plasma total cholesterol contents were significantly reduced in fish fed the diet with the highest BSFM level(BSFM30). These results indicate that BSFM has potential as alternative to FM in practical diets for juvenile mandarin fish and can be used substitute for fish meal up to 25% in diet.
