Ecological feed of clarias fuscus and preparation method thereof

Abstract

The present invention belongs to the technical field of aquaculture and particularly relates to an ecological feed for clarias fuscus and a preparation method thereof. Through reasonable matching andtreating, properties of a mixture of chicken manure, soybean meal, corn distiller's grains, earthworm powder, dried water grass, rapeseed meal, EM (effective microorganisms), soybean oil, edible salt,vitamins and trace elements are blended together; the matching is conducted according to the proportions; the effects of the various raw materials are fully made use of; and finally the ecological feed for the clarias fuscus is obtained. The ecological feed for the clarias fuscus is wide in sources of the raw materials, low in costs, reasonable in matching and rich in nutrients, can be prepared at any time when used, is good in palatability for the clarias fuscus, can meet nutritional needs of the clarias fuscus, can also reduce the prevalence of the clarias fuscus and promotes the growth ofthe clarias fuscus.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a bearded catfish ecological feed and a preparation method thereof. Background technique [0002] Beard catfish belongs to Siluriformes, Beard Catfish family, also known as Tangjiao, Tutangjiao, and local Tangjiao. It grows in the south of the Yangtze River and is widely cultivated in Guangdong, Guangxi, Fujian and other areas. It grows fast and has strong disease resistance. The cost of breeding is low, the output is high, and the economic benefit is high, so it is loved by farmers. Its meat is tender and delicious, and has the nourishing effect of nourishing the brain and nourishing qi, as well as certain medicinal value. Fish meat contains more protein, calcium, phosphorus and various trace elements, and is a nutritious and healthy food.

AI Technical Summary

Problems solved by technology

[0003] In recent years, with the continuous fishing of bearded catfish, the wild survival is very small, mainly relying on artificial breeding to supply the market, but the feed for breeding has become the main factor restricting the development of the bearded catfish aquaculture industry. The use of special feed for bearded catfish can provide fish The body provides comprehensive nutrition, but it will increase the cost of breeding, and the market price will also increase after cultivation

Especially for small farmers, if they use commercially available beard catfish special feed, the cost will increase to an unbearable level

Therefore, many farmers generally prepare the feed of bearded catfish by themselves, but they lack scientific decision-making and technical guidance, and often only use one or a few conventional feed ingredients to prepare feed, resulting in incomplete nutrition, slow growth and easy disease of bearded catfish. Among them, the proportion of nutrients is inappropriate and it is easy to overfeed, and the remaining raw materials will pollute the breeding waters, causing frequent occurrence of diseases in the breeding process, further leading to the loss of bearded catfish and the increase of breeding costs
