Abstract

The present invention discloses an adult oncorhynchus mykiss compound feed low in nitrogen and phosphorus emissions. The compound feed comprises the following components in parts by weight: 40-55 parts of compound protein components, 2-5 parts of compound amino acid components, 10-20 parts of compound oil components, 2-5 parts of compound insecticide components, 3-5 parts of special color-enhancing components, 2-5 parts of micro-ecological preparations, 5-15 parts of corn gluten meal, 5-15 parts of vital wheat gluten, 0.01-0.1 part of vitamin mixture and 0.02-0.2 part of mineral mixture. The compound feed conforms to the raptatorial features of the oncorhynchus mykiss and meets the needs of the adult oncorhynchus mykiss to high protein through adding the compound protein components into the compound feed. By feeding the compound feed to the adult oncorhynchus mykiss, the body color can be improved, the occurrence of parasitic diseases can be reduced, the growth of the adult oncorhynchus mykiss can be promoted, and the breeding efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed, and in particular relates to a compound feed for adult rainbow trout with low nitrogen and phosphorus discharge. Background technique [0002] Rainbow trout belongs to Salmoniformes and Salmonidae. It is a kind of cold-water fish. Its origin is in the mountains and rivers along the Pacific coast of North America. It likes to inhabit waters with clear water, low water temperature, more dissolved oxygen and abundant flow. Because it is suitable for artificial intensive farming, and has high yield, high farming efficiency, and broad market prospects, it has become one of the most widely farmed fishes in the world. With the introduction of rainbow trout in my country in recent years, the industry has developed rapidly, and both the aquaculture area and the aquaculture output are increasing rapidly. [0003] However, in the current rainbow trout breeding process, due to the lag in nutrition res...
