Embodiment 1

[0017] A method for cultivating zinc-rich catfish, comprising the following steps:

[0018] (1) Breeding of broodstock: 40 to 50 days before artificial breeding, select well-proportioned catfish broodstock to stock in male and female fish ponds respectively, and feed female fish feed and male fish feed respectively;

[0019] (2) Artificial insemination: During artificial insemination, after egg cells are taken out, add semen, stir gently, and after 20 to 25 minutes, add zinc sulfate solution with a mass fraction of 0.06%, the amount added is 1 / 3 of the volume of semen, and mix Uniform, get fertilized eggs;

[0020] (3) Fry management: move the fry from the hatching pond to the fry cultivation pond, put in the fry feed, 1~6 days, the input amount is 9.6% of the fry weight, 7~18 days, the input amount is 9.2% of the fry weight, 19~ For 30 days, the daily input amount is 8.7% of the fry weight, and the fixed-point and regular input is divided into 4 times every day;

Abstract

The invention relates to the field of cultivation, and discloses a cultivation method for zinc enriched catfish. The cultivation method comprises: parent fish breeding, artificial insemination, management of fish fry, and management of adult fish. The method is easy, the fertilization rate of catfish is 93%, the hatching rate is 91%, the survival rate is 72%, the organic zinc content reaches 8.14mg / 100g, and the economic income is increased by 13.2%; Male and female fish are fed with different feeds, absorption is promoted, organic zinc content in reproductive cells is increased, and the reproductive ability of the parent fish is enhanced; after fertilization, zinc sulfate solution is added to increase the fertilization rate and vitality, and the hatching rate is significantly increased; fry feeding is conducted according to different stages, growth is accelerated, resistance is enhanced, and survival rate is increased; the parent fish is only fed with artificial feed, the nutrition is balanced, zinc content is high, and the organic zinc in adult fish body is increased; all feeds are fermented by Deshi lactobacillus to promote digestion and absorption of catfish, and enhance catfish stress resistance.

Description

technical field [0001] The invention mainly relates to the technical field of cultivation, in particular to a method for cultivating zinc-enriched catfish. Background technique [0002] Catfish (catfish), also known as bearded catfish, sticky fish, pond louse fish, raw fish. Rich in nutrition, the whole body is a treasure, rich in protein and mineral elements, and is a treasure among fishes. It can promote lactation, remove edema, strengthen muscles and bones, and prolong life. Zinc is one of the essential trace elements for the human body. It can promote growth and development, enhance intelligence, maintain normal appetite, enhance immunity, promote wound healing, promote vitamin A absorption, protect eyesight, and beautify skin care. [0003] In the cultivation of catfish now, conventional cultivation is mainly carried out, and the zinc content of catfish meat is less, which cannot satisfy the nutritional and health care needs of consumers. Therefore, a method for cultiv...
