Feed capable of promoting propagation capacity of schizothorax taliensis

Abstract

The invention provides a feed capable of promoting propagation capacity of schizothorax taliensis. The feed comprises the following raw materials in parts by weight of 55-65 parts of fish meal, 30-40parts of castor seed cakes, 8-16 parts of shrimp powder, 10-20 parts of wheat flour, 20-30 parts of soybean meal, 16-25 parts of corn protein powder, 15-26 parts of peanut meal, 1-3parts of a feed additive, 1.5-2.5 parts of soybean phospholipid and 0.9-1.8 parts of a multi-vitamin premix, wherein the feed additive comprises the following raw materials in parts by weight of 16-24 parts of earthwormextracts and ferrous fumarate, 12-18 parts of coix seeds, 6-12 parts of black rice, 5-10 parts of kudzu vine flowers, 4-8 parts of radix astragali, 1-2 parts of turtle shells, 0.8-1.6 parts of unsaturated fatty acid and 15-20 parts of carriers, the earthworm extracts and the ferrous fumarate need to be subjected to magnetisation treatment in advance, and the mass ratio of the earthworm extracts to the ferrous fumarate is (60-70) to 1. The feed can increase the propagation capacity, the hatching rate and the larva fish survival rate of the schizothorax taliensis.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a feed for promoting the fecundity of anti-wave fish. Background technique [0002] Kanglang fish, formerly known as Chilang white fish, belongs to the genus Cyprinidae of Cyprinidae. 100 specimens were measured, with a total length of 124-186 mm. The body is slender and slightly flattened, and the entire body outline is like a long and narrow spindle; the back is straight, the belly is shallowly curved, and the head length is significantly longer than the body height. It is a second-class protected animal in the country and is produced in Yunnan, my country. However, with the invasion and overfishing of alien species, the population of Kanglang fish has declined sharply, and it has gradually withdrawn from the table of ordinary people. At the same time, the artificial breeding of endangered Kanglang fish has also been put on the agenda. Since 2000, the Aquatic Produc...

Problems solved by technology

In the current artificial breeding method, most of the nutrition in the parent fish of Kanglang fish is transformed into the development of sex cells, which makes the body condition of the parent fish decrease, the fecundity is weakened, the number of eggs laid is reduced, the quality of the eggs produced is not high, and the fertilization rate, hatching rate, and survival rate of larvae decline to varying degrees
