真鲷幼鱼对饵料中蛋白质、脂肪、碳水化合物需求量的研究

The requirements of protein, fat and carbohydrate of Juvenile Red Seabream(Pagrus major (T&S))

采用 9种人工配合饵料 ,研究真鲷 (Pagrusmajor(T&S) )幼鱼饵料中的蛋白质、脂肪、碳水化合物的需求量。在 4 5d的试验期内 ,蛋白质、脂肪、碳水化合物含量分别为 4 4 6 %、17 6 %、15 5 %时 ,真鲷幼鱼生长最快。饵料系数为 1 4。

Using nine formulated diets with multivariated analysis,the optimum requirements of protein, fat and carbohydrate of juvenile red seabream were studied. The fish feeded on diet 4(Pr.: 44 6%, Fat: 17 6%, Carbohydrate: 15 5%) grew most rapidly, final fish gain and food conversion ratio (FCR) was 208 3 and 1 4 respectively.
