Problems solved by technology

However, in recent years, the price of perch has dropped, and the cost of breeding has risen with the rise of prices. In order to obtain the maximum breeding benefits, fish farmers have to increase the density of breeding. The average density reaches 1500kg / mu of water, the highest The water area reaches 5000kg / mu, and with the development of intensive and high-density farming, the outbreaks of perch breeding diseases are becoming more and more frequent and serious, and the development of existing feed and medicine cannot meet the needs of intensive, high-density farming. The need for density farming

Embodiment 3

[0037] Embodiment 3: breeding test

[0038] Bass cultured in 3m*3m*3m cages were used for breeding experiments. The cage setting area has no pollution sources around it, and the river with a water depth of about 5m enters the sea. The water surface is relatively wide, the bottom is flat, the water flow is smooth, the wind is sheltered and the water level is relatively stable. , the water quality is fresh. The transparency of the water body is about 50cm, the pH value is 7.4-8.2, and the dissolved oxygen content is above 5.1mg / L. The length of perch entering the box is 5-7cm, and the stocking density is 30 fish per square meter of water area, that is, 270 fish are stocked in each cage, and fed with compound feed. A total of 6 net cages were used in the test, and net cage 1 was the blank control group, which was fed with conventional commercial perch compound feed; net cage 2-3 was the test group, and the feed fed by it was the conventional perch compound feed. Added the fee...

Abstract

The invention relates to a special feed additive for bass and a preparation method of the feed additive. The feed additive is prepared from the following raw materials by weight parts: 10-20 parts of folium ginkgo, 1-3 parts of artemisia apiacea, 2-4 parts of radix isatidis, 1-4 parts of folium isatidis, 0.5-1 part of radix stemonae, 5-7 parts of purslane, 5-7 parts of fresh herba houttuyniae, 5-7 parts of apricot kernels, 1-5 parts of montmorillonite, 7-10 parts of pine needle meal, 3-5 parts of maca powder, 20-30 parts of fresh earthworms and 0.2-0.5 part of sumac fruit oil. The feed additive has positive meaning on concentrated and high-density breeding of the bass, especially the problems of water body pollution and relatively poor bass flavor caused by feed deposition in feeding of a conventional granulated feed can be solved, the disease resistance of the bass can be improved, the bass growth can be promoted, the survival rate of bass breeding is greatly increased, and the economic income of bass breeders is remarkably improved.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a special feed additive for perch and a preparation method thereof. Background technique [0002] Perch is also known as flower perch, Zhaihua, perch board, seven-star perch, four-rib fish, etc., commonly known as perch, and belongs to Perciformes and Lipidaceae in taxonomy. Fish" one. Bass meat is white and tender, fragrant, without fishy smell, and the meat is in the shape of garlic cloves. It is most suitable for steaming, braised in soy sauce or stewed soup. The fishing season is spring and autumn, and October to November is the peak fishing season, especially at the end of autumn and early winter. The mature perch is particularly plump, and the nutrients accumulated in the fish are also the most abundant, so it is the best to eat perch season. Bass likes to live in brackish and fresh water in estuaries, and can also live in fresh water. It is distributed in the western Pac...
