Problems solved by technology
[0003] At present, there are very few studies on the nutritional requirements and feed of the high-backed crucian carp in Dianchi Lake, and there is no special compound feed. Its artificial breeding often borrows artificial compound feed from other cultured fish, which is likely to cause pollution of the breeding waters, high feed coefficient and low breeding efficiency. Serious consequences

Abstract
The present invention relates to compound feed for adult fish of carassius auratus, belonging to the technical field of aquaculture. The compound feed comprises the following ingredients by weight: 7-14% of domestic fish meal, 6-9% of corn gluten meal, 22-28% of soybean meal, 12-16% of cottonseed meal, 10-13% of rapeseed meal, 7-9% of rice bran, 5.83-9.63% of wheat middling, 4-6% of Saccharomyces cerevisiae, 4.5-5.3% of soybean oil, 0.5-1.0% of soy lecithin, 0.7-1.5% of calcium dihydrogen phosphate, 0.05-0.1% of L-ascorbate-2-monophosphate, 3-4% of zeolite powder, 0.2-0.3% of choline chloride, 0.2-0.4% of salt, 0.01-0.03% of ethoxyquin, 0.5-1.0% of mineral premix, and 0.3-0.8% of vitamin premix. According to the present invention, habits, nutritional needs and digestion characteristics of carassius auratus are fully taken into account, and the compound feed is reasonable in combination by selecting raw materials easily digested and absorbed by carassius auratus, and has good palatability, a high feed conversion ratio, little pollution to water bodies, stable sources of raw materials, and low cost, suitable for large-scale adult fish farming of carassius auratus.
Description
technical field [0001] The invention relates to a compound feed, in particular to a compound feed for high-back crucian carp in Dianchi Lake, and belongs to the technical field of aquaculture. Background technique [0002] Dianchi high-backed crucian carp (Carassius auratus) belongs to Cyprinidae, Cyprinidae, Cyprinidae, and Carassius genus. It is a triploid crucian carp population (high body type) naturally formed in Dianchi Lake and its water system in the 1970s. It is all female Group, parthenogenetic reproduction, maintains the stability of the variety traits and the continuation of group survival, and becomes a rookie in the crucian carp family. Dianchi high-backed crucian carp has the characteristics of rapid growth, strong fecundity, strong disease resistance, wide feeding habits, large individuals, and easy breeding. Generally, the second-year-old can reach 300-500 grams, and the third-year-old can grow to more than 1,000 grams. The growth rate of high-backed crucia...
