Abstract

The invention discloses a feed additive capable of resisting high sea state stress for silver salmon and a preparation method of the feed additive. The feed additive comprises the following components: an enteromorpha extract, a liquorice root extract, a jerusalem artichoke extract, gamma-aminobutyric acid, natural astaxanthin, vitamin C and vitamin E. According to the feed additive capable of resisting high sea state stress for silver salmon and the preparation method of the feed additive, the components are respectively weighed, uniformly mixed, ground by an ultrafine grinder and sieved by a 150-mesh sieve, and the powdery feed additive capable of resisting high sea state stress for silver salmon is prepared. The antioxidant capacity, the immunity and the anti-stress capacity to high sea state of organisms are improved, the survival rate is increased, and healthy growth of the silver salmon is promoted.

Description

technical field [0001] The application relates to the field of aquatic feed additives, in particular to a feed additive for coho salmon with high sea state stress resistance and a preparation method thereof. Background technique [0002] Coho salmon, also known as coho salmon, belongs to Herringformes, Salmonidae, and Salmon. After growing into adults, they migrate to fresh water to spawn and complete their growth cycle. The flesh of coho salmon is bright orange and has a good taste, which can arouse people's appetite. It is an excellent raw material for making sashimi and other delicacies. Because it is rich in unsaturated fatty acids, it can effectively prevent cardiovascular and cerebrovascular diseases and diabetes, etc. some diseases. Accordingly, some provinces in Canada are funded by the government to make public service advertisements on TV, advising people to eat more cold-water fish like coho to prevent diseases. Because coho salmon has the characteristics of hi...
