Novel feed for juvenile fish of pelteobagrus fulvidraco

Abstract

The invention relates to the technical field of aquaculture and particularly relates to a novel feed for juvenile fish of pelteobagrus fulvidraco. The feed is composed of, by mass, 20-40 parts of brown fishmeal, 15-20 parts of flour, 5-10 parts of flour, 15-20 parts of soybean meal, 4-8 parts of peanut bran, 5-10 parts of rapeseed meal, 15-20 parts of corn protein powder, 1-2 parts of soybean oil, 1-3 parts of fish oil, 0.5-1.5 parts of monocalcium phosphate, 0.5-1 part of composite vitamins, 0.5-1 part of composite minerals, 2-3 parts of Chinese herbal medicines, 0.2-0.5 parts of an organic acid phagostimulant, 0.3-0.7 parts of choline chloride, 0.1-0.3 parts of a mildew proofing agent, and 0.2-0.4 parts of an antioxidant. In the invention, Chinese herbal medicines are added to a conventional pelteobagrus fulvidraco feed, so that survival rate of the juvenile fish of pelteobagrus fulvidraco is effectively increased, darkened body color is prevented and bright body color under a wild status of the pelteobagrus fulvidraco can be maintained, thereby improving quality of the juvenile fish. Meanwhile, the Chinese herbal medicines has spectral sterilization effects, so that pathogenic bacteria in water body can be killed effectively, thereby improving situation of water body, increasing the survival rate of the pelteobagrus fulvidraco, reducing application of chemical reagents and reducing breeding cost.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a novel feed for juvenile yellow catfish. Background technique [0002] Yellow catfish, also known as yellow-cheeked fish, yellow-bone fish, and yellow stickleback fish, is distributed in the Yangtze River, Yellow River, Pearl River, and Heilongjiang River Basin in China. It has the effects of clearing milk, nourishing the body, and promoting recovery; it has the effects of appetizing and invigorating the spleen, eliminating cold air, and promoting milk production; it tastes bitter, can clear the heart and fire, clear away heat and troubles, and eliminate heat toxins in the blood; it is also rich in Nutrients, which are rich in protein, can maintain potassium and sodium balance, remove edema, improve immunity, lower blood pressure, buffer anemia, and help growth and development; rich in copper, copper is an indispensable micronutrient for human health, for blood, The central...

Problems solved by technology

[0003] In view of the high medicinal value and edible value of yellow catfish, the market demand for yellow catfish has been increasing day by day in recent years. Taking Guangxi as an example, the local yellow catfish farming has reached a certain scale, and the farming technology is improving day by day. Feed companies have simultaneously developed artificial compound feeds for different stages of yellow catfish, which has promoted the rapid development of the yellow catfish aquaculture industry; the technology for developing compound feeds for juvenile yellow catfish has also gradually matured, but these juvenile fish feeds have not been developed. To solve the problem of color fading of juvenile yellow catfish, especially when some farmers expand the scale of farming and increase the breeding density, they ignore the problem of discoloration of juvenile yellow catfish that often occurs due to environmental changes or feed management problems, resulting in Although the growth rate and output of juvenile yellow catfish are improved due to the improvement of artificial compound feed formula,
