Feed for juvenile schizothorax taliensis

Abstract

The invention provides feed for juvenile schizothorax taliensis. The feed comprises, by weight, 20-30 parts of wheat bran, 30-40 parts of fish meal, 5-10 parts of plant oil, 5-8 parts of lotus root starch, 3-5 parts of yam flour, 5-8 parts of glucose, 20-30 parts of bean pulp, 10-15 parts of raw eggs, 10-12 parts of earthworm powder, 5-8 parts of soybean lecithin, 8-10 parts of fish oil, 5-10 parts of inkfish grease, 0.3-0.5 part of monocalcium phosphate, 0.1-0.2 part of phagostimulant, 10-15 parts of strong flour, 1-2 parts of mineral additives, 0.5-0.8 parts of vitamin additives, 0.3-0.8 part of vitamin C acetate, 0.03-0.05 part of high-temperature-resisting phytase, 0.03-0.08 part of hymecromone, 8-12 parts of dried pig blood and 0.1-0.3 part of yeast extract. The feed for the juvenileschizothorax taliensis has the advantages that the content of protein and grease is high, nutrient substances are balanced, the juvenile schizothorax taliensis absorbs and digests the nutrient substances conveniently, growth speed of the schizothorax taliensis is increased, feeding of the schizothorax taliensis is promoted, and palatability of the feed is improved.

Description

technical field [0001] The invention relates to the field of aquatic feed, in particular to a feed for juvenile Schizothorax. Background technique [0002] Schizothorax is also called Yayu, thin soft-shelled turtle, and Qikou slender scale fish. It is a cold-water fish and a bottom fish. It requires a lower water temperature environment. In the slow-flowing Tuozhong, the feeding season is active in an environment with sand and gravel as the bottom and turbulent water flow. There is a short-distance reproductive migration phenomenon. Females need to reach sexual maturity at 4 years old, and males generally reach sexual maturity at 3 years old. Schizothorax is distributed in water systems such as the Minjiang River and the Dadu River, and is an important edible fish in the upper reaches of the Yangtze River. The individual is large, generally 0.5-1.0kg, and the maximum can reach 4.0-5.0kg. Because of its plump meat and rich fat, it is deeply loved by people. In recent years, ...

Problems solved by technology

Although there have been some reports on the culture of Schizothorax, there are few technologies specifically for artificial culture of Schizothorax

[0003] The Chinese patent applications whose publication numbers are CN102484983A and CN200410022179.7 respectively disclose methods for the artificial propagation of Schizothorax, mainly disclosing the cultivation conditions in the stages of insemination, hatching, and seedling cultivation, such as temperature, time, and environmental requirements. The bait for juvenile fish is only biological bait such as water worms or commercially available non-full-mouthed Schizothorax feed. Although this type of feed can provide more nutrients, the nutrition is not comprehensive and cannot meet the growth needs of juvenile fish. Substances and boost immunity of juvenile fish
