中文摘要:
      日本鲈(Lateolabrax japonicus)隶属鲈形目、脂科、鲈属,俗称花鲈、花寨、鲈板、七星鲈.因其肉质坚实,洁白细嫩、味道清香,并具药用价值,为消费者所喜爱.日本鲈是肉食性凶猛鱼类,是目前我国海水养殖鱼类产量最高的品种.当前沿海养殖生产所用饵料中冰鲜杂鱼占了很大比例,但由于资源匮乏和对养殖水体的污染非常严重,对日本鲈营养需求和配合饲料的研究逐渐开展起来.由于日本鲈为肉食性鱼类,其饲料蛋白质含量在40%以上,并且一般以鱼粉作为主要的蛋白质来源.出于鱼粉资源及饲料成本的考虑,有必要寻找新的蛋白源来代替鱼粉.
英文摘要:
      An experiment was conducted to evaluate the effects of degossypolled cottonseed meal (DCM) on Japanese sea bass (Lateolabraxjaponicus,(5.04?0.02) g initial body weight). Five experimental diets DCM 0, DCM 25, DCM 50, DCM 75A, DCM 75 were formulated to contain 0, 15.2%, 30.5%, 46%, and 46% DCM to replace 0, 25%, 50%, 75%, 75% fish meal protein respectively, and the DCM 75 A was supplemented with lysine and methionine to be similar to DCM 0 for Japanese sea bass. Three tanks were randomly assigned to each diet, and 16 fish were batch weighed and stocked into each tank. Faecal were collected after 2 weeks of normal feeding for nutrients apparent digestibility coefficients (ADCs) determination, and the growth trial lasted for 8 weeks. The results showed that fish fed diets DCM 50 had significantlyhigher feed conversion ratio (FCR) and lower protein efficiency ratio (PER) than that of DCM 0 group ( P 〈 0.05). Fish fed DCM 75A and DCM 75 diets had significantly lower growth performances than those of fish fed diet DCM 0 ( P 〈 0.05 ), but the lysine and methionine supplement improved PER of diet DCM 75A diet. There were no significant differences in ADCs of dry matter, crude protein, crude lipid, energy and body composition. The present results indicate that DCM may be included in the diet up to 30.5 % as a substitute for fish meal, and it can replace about 50 % of fish meal protein.
