Feed additive special for microptenus salmoides freshwater aquaculture and preparation method thereof

Abstract

The invention relates to a feed additive special for microptenus salmoides freshwater aquaculture and a preparation method of the feed additive. The feed additive special for microptenus salmoides freshwater aquaculture is prepared from the following raw materials in parts by weight: 12-23 parts of folium ginkgo, 4-7 parts of artemisia apiacea, 9-12 parts of betel nut, 3-5 parts of folium isatidis, 5-7 parts of radix stemonae, 3-5 parts of portulaca oleracea, 5-7 parts of arctium lappa, 10-17 parts of fresh Chinese yam, 5-12 parts of fresh houttuynia cordata, 5-7 parts of apricot, 4-9 parts of montmorillonite, 3-7 parts of maca powder, 20-25 parts of fresh earthworm and 5-9 parts of yolk powder. The feed additive special for microptenus salmoides freshwater aquaculture, which is provided by the invention, can overcome the problems of water body pollution and poor flavor of microptenus salmoides which are caused by feed deposition in traditional granulated feed feeding, can improve the disease resistance of the microptenus salmoides, promote the growth of the microptenus salmoides, and improve the survival rate of microptenus salmoides aquaculture, and the economical benefit of microptenus salmoides farmers is also improved obviously.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a special feed additive for freshwater culture of California perch and a preparation method thereof. Background technique [0002] California bass, formerly known as largemouth bass, is covered with grayish-white or light yellow fine scales all over its body, but the color of the back line is darker, often greenish blue or light black, and there are often black markings along the side line. The abdomen is gray and white. It is a rare carnivorous fish with delicious meat, strong disease resistance, rapid growth, easy to catch, and wide temperature adaptability. California sea bass grows fast, and the fry that were bred that year can grow to 0.5 kg, reaching the market. Specification. One-week-old fish are sexually mature and can reproduce. No matter they are cultured in single ponds or polyculture in fish ponds, they can effectively control the excessive reproduction of wild fish,...

Problems solved by technology

However, for the above common diseases, strong disinfectants and antibiotics are usually used for treatment in the prior art. However, the use of chemical disinfectants will remain in the water body and seriously damage the microenvironment of the water body. The flavor of the raised California perch is relatively light. And it usually has a heavy fishy smell; and antibiotic treatment will lead to the emergence of drug-resistant bacteria, which greatly reduces the frequency of pond culture, often after 3-5 batches of culture can no longer be cultured, because strong resistant bacteria are produced in the water body. Drug-resistant bacteria are prone to large-scale disease outbreaks, and antibiotic residues can also cause serious food safety problems, which is not conducive to the sustainable and healthy development of the aquaculture industry
