Special feed for E.malabaricus

Abstract

A disclosed special feed for E.malabaricus is prepared by the following raw materials by weight ratio: 40-50 parts of fish meal, 10-15 parts of soybean meal, 6-10 parts of small peptide, 4-8 parts of shrimp meal, 4-8 parts of yeast powder, 12-16 parts of strong flour, 2-4 parts of fish oil, 1-2 parts of soya-bean oil, 1 part of choline chloride with a mass percent of 50%, 1 part of decavitamin, and 4 parts of composite minerals. After the special feed is added with small peptide, the yield of E.malabaricus in a cubic water body is improved by about 15 percent, the bait coefficient is reduced to less than 1.5, and the utilization rate of baits is substantially improved. Research shows that small peptide can be directly absorbed by animals and is taken as a substrate for synthesis of protein in cells, and plays an important role in digestion, absorption and metabolism of amino acid; also small peptide is capable of improving utilization rate of trace elements in the feed, promoting growth of fish bodies and enhancing immunity of the fish bodies. The special feed for E.malabaricus not only helps to enrich and develop theories of aquatic animal nutrition and feed science, but also helps culturists to acquire substantial economical benefit and social benefit.

Description

technical field [0001] The invention relates to a special feed for fish, in particular to a special feed for spotted grouper. Background technique [0002] Grouper is a general term for fishes of the order Perciformes, Percoidei, Serranidae, and Epinephelus. The common red-spotted grouper (E.akaara), Blue grouper (E.awoara), spotted grouper (E.malabaricus), giant grouper (E.tauvina), salmon-spotted grouper (E.fario), moire grouper (E.moara) , Seven-banded grouper (E.septemfasciatus), salmon-shaped grouper (E.salmonoides), brown-spotted grouper (E.fuscoguttatus), small-toothed grouper (E.microdon), striped grouper (E.fascia tus), nasu grouper (E.striatus), brown-spotted grouper (E.suilhs), perch talc grouper (E.laurina), etc. They are found in subtropical and tropical seas all over the world. It is an important marine cultured fish and one of the most important seawater cage cultured high-grade fishes in China. [0003] Spotted grouper (E.malabaricus) is commonly known as ...

Problems solved by technology

[0003] Spotted grouper (E.malabaricus) is commonly known as "green spot" in Fujian, Guangdong, Taiwan and other places. Due to its good meat quality, fast growth, and easy live transportation, it has become an important mariculture object in the southeast coast of my country in recent years. , but there is no special feed for grouper in China, and most of the feeds selected are general-purpose feeds for seawater fish, resulting in high feed coefficient and frequent occurrence of nutritional diseases, which is not conducive to the healthy development of grouper aquaculture.
