Problems solved by technology

[0003] At present, there are no research reports on the nutritional requirements and feeds of adult fishes of the chrysalis, and there is no special compound feed. The artificial breeding is mainly fed fresh miscellaneous fish such as freshwater pomfret directly or replaced by other fish feeds. These feeds are from To a certain extent, it solves the problem of feed for adult fish of silktail fish, but fundamentally speaking, it does not meet the nutritional requirements of silktail fish, and cannot achieve optimal feeding. The pollution of the environment causes the breeding of diseases, the abuse of drugs, and endangers the safety of human food

Abstract

The present invention relates to compound feed for adult fish of mystus nemurus, belonging to the technical field of aquaculture. The compound feed comprises the following ingredients by weight: 10-18% of domestic fish meal, 16-21% of soybean meal, 11-15% of cottonseed meal, 6-10% of rapeseed meal, 6-8% of corn gluten meal, 6-8% of rice bran, 13.23-20.23% of wheat middling, 4-6% of Saccharomyces cerevisiae, 2.1-2.5% of fish oil, 5.2-5.6% of soybean oil, 0.5-1.0% of soy lecithin, 0.8-1.5% of calcium dihydrogen phosphate, 0.05-0.1% of L-ascorbate-2-monophosphate, 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, the compound feed is reasonable in ingredient ratio, balanced in nutrition, low in feed coefficient and cost and easy to spread; and the feed 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 mystus nemurus.

Description

technical field [0001] The invention relates to a compound feed, in particular to a compound feed for adult fish of silktail carp and belongs to the technical field of aquaculture. Background technique [0002] Silktail fish (Hemibagrus wyckioides) belongs to the Siluriformes, Oleidae, and Hemiformes. It is also known as long-bearded fish. It is a valuable economic fish in the Lancang-Mekong River Basin. Ivetail carp has the advantages of fast growth, large individual (up to 80kg), wide adaptability, strong disease resistance, low oxygen resistance, etc., and its meat is white and tender, delicious, without intermuscular spines, and can be made into sashimi , the economic benefits of farming are much higher than other freshwater fish, and are favored by farmers and consumers. Silktail is an omnivorous fish mainly of animal nature. Under natural conditions, juvenile fish feed on plankton, while adult fish feed on larvae, small fish, aquatic insects, water worms and organic d...
