近年来,有关淡水鱼类对必需脂肪酸要求的研究大有进展。迄今,对虹鳟、鲤鱼、鳗鲡、银大麻哈鱼、大麻哈鱼的必需脂肪酸要求已经查清。并且,各种鱼类多少显示种的特异性。可以将其分成两大类,即以亚麻酸为必需脂肪酸的鱼类(虹鳟、银大麻哈)和以亚油酸和亚麻酸为必需脂肪酸的鱼类(鲤鱼、鳗鲡、大麻哈)。但是,最近鹿儿岛大学水产学部和东京大学鱼类营养教研室分别对红腹罗非鱼 Tillapia zillii 和尼罗罗非鱼的必需脂肪酸要求研究结果表明,亚油酸对这两种鱼类的生长促进效果强于亚麻酸。而且,在
In recent years, research on the requirements for essential fatty acids in freshwater fish has greatly advanced. So far, the requirements for essential fatty acids of rainbow trout, carp, eel, silver salmon and salmon have been identified. And, the number of species of fish showed species specificity. It can be divided into two broad categories, namely, fish with linoleic acid as essential fatty acids (rainbow trout, silver marijuana) and fish (carp, eel, marijuana) having linoleic and linolenic acids as essential fatty acids. However, recent studies on the essential fatty acid requirements of Tilapia zillii and Nile tilapia, respectively, by the Department of Fisheries, Kagoshima University and the Department of Fish Nutrition, The University of Tokyo showed that the effect of linoleic acid on the growth of both species Promote better than linolenic acid. And, at
