Green and healthy sea fish feed and application thereof

Abstract

The invention provides green and healthy sea fish feed, which is prepared from the following components in parts by weight: 20-40 parts of flour, 15-30 parts of earthworm powder, 15-20 parts of silkworm chrysalis meal, 10-15 parts of white sugar, 8-15 parts of vitamin C, 1-3 parts of trace elements, 1-3 parts of flavorant, 0.3-0.7 part of dietary fiber, 10-20 parts of fructus lycii, 0.8-1.5 parts of a complex enzyme preparation, 0.00002-0.00006 part of jamestownweed seed and 0.005-0.008 part of dimethylpropiothetin. The green and healthy sea fish feed has the beneficial effects that the prepared sea fish health care feed is reasonable in nutrient structure, and can meet the demand of sea fish growth for amino acids, vitamins and mineral substances so as to promote the growth of sea fish; furthermore, the sea fish feed also can improve the absorption of the sea fish for nutrient substances and the trace elements of the feed, so that the feed utilization rate of the sea fish is improved; the sea fish feed can improve the immunity, and is free from antibiotics, thus enabling the sea fish not to have drug resistance and being green and safe; fresh fish bait is replaced with commercially available dry powder, so that the sea fish feed is environment-friendly; furthermore, the green and healthy sea fish feed is not limited by a fishing forbidding period or seasons, and is good in product quality; therefore, the green and healthy sea fish feed can be applied to artificial breeding of the sea fish.

Description

technical field [0001] The invention relates to the technical field of feed preparation, in particular to a green and healthy seawater fish feed and its application. Background technique [0002] The large-scale development of marine fish farming in my country began in the late 1970s. The farming methods include pond farming, land-based factory farming, and cage farming. There are many problems in terms of production, such as the lack of high-quality series of compound feeds, frequent occurrence of diseases, and poor safety and hygiene quality of farmed fish. Breeding feed is the material basis for fish to survive, grow and reproduce, so high-quality farming feed is one of the weight factors for fish survival and life. At present, the commonly used fish feed is fresh bait. The pumping and feeding of fresh bait not only causes waste of resources and pollutes the breeding environment, but also the supply of fresh bait is restricted by the fish ban period and season, and its qu...

AI Technical Summary

Problems solved by technology

Currently, the commonly used fish feed is fresh bait. The pumping and feeding of fresh bait not only causes waste of resources and pollutes the breeding environment, but also the supply of fresh bait is restricted by fish ban period and season, and its quantity, freshness and quality are not guaranteed. As a result, the contradiction between supply and demand of fresh and live bait, and the contradiction between aquaculture and water environment are prominent, which can easily induce the occurrence of diseases of aquaculture species and affect the sustainable development of fish aquaculture industry. Therefore, it is imperative to develop efficient and safe bait for the development of aquaculture.
