一种提高鲑鳟鱼免疫力的鱼苗饲料
本专利技术涉及水产饲料
,尤其涉及一种提高鲑鳟鱼免疫力的鱼苗饲料。
技术介绍
天然洄游鲑鳟鱼类依赖于自然界饵料生物的类胡萝卜素色素和虾青素,呈现深受消费者喜爱的橙红肉色。人工饲养的鲑鳟鱼类,相对在自然环境生长的同种野生鱼类而言,粗蛋白较少、香味淡、鱼肉颜色较差、适口性欠佳。养殖生产时鲑鳟鱼类橙红肉色依赖于饲料中类胡萝卜素色素沉积,而养殖鲑鳟鱼普遍缺乏微量元素和类胡萝卜素。动物肌体中的香味成分多数是C3H5-S(O)-基团,鲑鳟鱼的配合饵料中较缺乏此成分,因此养殖的鱼香鲜味较淡。所以要想满足消费者需求,养殖洄游鲑鳟鱼类鱼肉必须着色成天然鲑鳟鱼类肉色,同时增加鱼肉的香味。
技术实现思路
本专利技术旨在解决鲑鳟鱼类养殖过程中,鱼肉香味淡、颜色较差、肉质疏松的问题而提供一种提高鲑鳟鱼免疫力的鱼苗饲料。为了实现上述目的,本专利技术采用以下技术方案:一种提高鲑鳟鱼免疫力的鱼苗饲料,所述鱼苗饲料的组份及质量百分比为:鱼粉50-60%、高筋面粉13-18%、肉骨粉5-10%、大豆粉3-8%、发酵豆粕2-4%、磷虾粉1-4%、酵母粉1-3%、鱼油1 ...
