Description

technical field [0001] The invention belongs to an animal feed, in particular to an Atlantic salmon feed. Background technique [0002] Atlantic salmon, also known as "salmon", is a species of salmonids, salmonids, and salmonids. It is divided into two types: migratory and land-sealed. Native to the Pacific coast of North America, it is a cold-water fish. Under natural conditions, it mostly grows in water bodies where the annual water temperature does not exceed 20 °C and the water quality is oligotrophic. It is a ferocious fish and feeds on small fish and shrimp under natural conditions. . Its unique therapeutic effect and rich nutritional content are well known, and it is the representative of precious cold water fish. In foreign countries, the research on the artificial breeding technology of migratory Atlantic salmon has gone through a considerable period of time. Triploid salmon, all-female salmon, high temperature-resistant salmon and other varieties have been succes...

AI Technical Summary

Problems solved by technology

In foreign countries, research on the artificial breeding technology of migratory Atlantic salmon has gone through a considerable period of time, and has successfully bred triploid salmon, all-female salmon, high-temperature-resistant salmon and other species, and successfully mastered the breeding technology of Atlantic salmon. A large number of fish eggs and fry are produced every year, but these results are limited to the cultivation of migratory Atlantic salmon in seawater. Although my country has invested tens of millions and spent more than ten years on salmon research, it has stagnated in basic applications due to various reasons. Research status, progress is slow. Shandong, Hebei, Beijing and western provinces are engaged in cold-water fish farming and research mainly Atlantic salmon. The output is increasing at a rate of 20% to 30% per year, but the quality of their fish products is declining. , High incidence of fish disease, low survival rate, unable to carry out large-scale high-density farming of Atlantic salmon, the main reason for these problems is that the feed cannot meet the survival and growth requirements of salmonid fish
