Abstract

The invention discloses a feed promoting silver salmon gonad development. The feed is composed of the following components by weight: 38 parts of fish meal, 3 parts of shrimp shell powder, 4 parts of Euphausia superb powder, 9 parts of beer yeast, 4 parts of phospholipid powder, 5 parts of skim milk powder, 6 parts of flour, 6 parts of alpha-starch, 20 parts of fish oil, 5 parts of soybean oil, 4 parts of olive oil, 0.7 part of vitamin C, 0.4 part of vitamin E, 0.15 part of dunaliella salina powder, 0.15 part of Haematococcus pluvialis powder, 2.5 parts of n-3HUFA, 0.15 part of taurine, 1.5 parts of choline chloride, 0.02 part of D-calcium pantothenate, and 1 part of calcium dihydrogen phosphate. The feed provided by the invention meets the requirement of silver salmon parent fish for nutrition, can induce silver salmon to eat, improves the immunity of parent fish, promotes silver salmon gonad development, and increases the energy needed by parent fish growth and development.

Description

technical field [0001] The invention relates to a fish feed, in particular to a feed for promoting gonad development of coho salmon. Background technique [0002] Coho salmon, also known as coho salmon, is known as salmon in the market. It belongs to Herringomorpha, Ranaidae, and Salmon genus, and is an anadromous migratory fish. Coho salmon spawn and develop in freshwater until they reach adulthood and swim out to sea. After growing into adults in the sea, they return to freshwater to lay eggs and complete their growth cycle. Coho salmon's original habitat is mainly in the eastern part of the Pacific Ocean, that is, the west coast of the United States and Canada, and it is a cold-water fish. [0003] Coho salmon has bright red flesh, few intermuscular spines, large edible part, high-quality fish meat, no fishy smell, good quality and delicious taste. It is the first choice for making sashimi. Its eggs are the raw materials of caviar, a high-end nutritional food. Fish me...
