Problems solved by technology

[0002] The yellow catfish belongs to the Siluriformes, the family Pleurotus, and the genus of the yellow catfish. It is a high-quality and valuable economic fish in freshwater waters. It is loved by people because of its delicious meat. Artificial breeding of yellow catfish has been carried out in many parts of the country, and the scale of farming has increased year by year. In 2015, the cultured output of yellow catfish in my country exceeded 350,000 tons
Fry breeding of catfish and other Siluriformes is basically artificial induced labor, multiple injections of drugs, killing males and extracting sperm, and hatching in special hatching tanks; this leads to a serious imbalance in the ratio of males and females in natural waters, resulting in serious depletion of natural resources. There are certain hidden dangers in safety, and the work efficiency of artificial injection induced labor technology is slow. Therefore, it is necessary to find a method that can solve the above problems

Embodiment 1

[0025] A method for artificial propagation and breeding of yellow catfish, comprising the following steps:

[0026] (1) Screening of parents: Select the large yellow catfish that is about to mature at the same period. Female and male fish are raised separately and fed the same feed until they are fully mature. The yellow catfish at the same period are reared after birth Yellow catfish of 5-6 months, with a weight of 80-100g, the feed is cooked with sweet potatoes, mashed and mixed with bananas, added with shrimp shell powder, sweet potato stems and leaves, corn, glucose, and completely crushed Mix and dry and then pulverize to form; the parts by weight of each ingredient in the feed are 80 parts of sweet potatoes, 10 parts of bananas, 20 parts of shrimp shell powder, 70 parts of sweet potato stems and leaves, 30 parts of corn, and 1 part of glucose;

[0027] (2) Oxytocin before breeding: add oxytocin to feed for a period of time, increase white light irradiation at the same ti...

Embodiment 2

[0032] A method for artificial propagation and breeding of yellow catfish, comprising the following steps:

[0033] (1) Screening of parents: Select the large yellow catfish that is about to mature at the same period. Female and male fish are raised separately and fed the same feed until they are fully mature. The yellow catfish at the same period are reared after birth 6-month-old yellow catfish with a body weight of 100g. The feed is cooked with sweet potatoes, mashed and mixed with bananas, added with shrimp shell powder, sweet potato stems and leaves, corn, glucose, completely crushed, mixed and dried again Pulverized and formed; the parts by weight of each ingredient in the feed are 120 parts of sweet potatoes, 50 parts of bananas, 60 parts of shrimp shell powder, 100 parts of sweet potato stems and leaves, 40 parts of corn, and 3 parts of glucose;

Embodiment 3

[0039] A method for artificial propagation and breeding of yellow catfish, comprising the following steps:

[0040] (1) Screening of parents: Select the large yellow catfish that is about to mature at the same period. Female and male fish are raised separately and fed the same feed until they are fully mature. The yellow catfish at the same period are reared after birth Yellow catfish of 5-6 months, with a weight of 80-100g, the feed is cooked with sweet potatoes, mashed and mixed with bananas, added with shrimp shell powder, sweet potato stems and leaves, corn, glucose, and completely crushed Mix and dry and then pulverize to form; the parts by weight of each ingredient in the feed are 100 parts of sweet potatoes, 30 parts of bananas, 45 parts of shrimp shell powder, 85 parts of sweet potato stems and leaves, 35 parts of corn, and 2 parts of glucose;

Abstract

The invention discloses a method for artificial propagation and breeding of yellow catfish. Mature yellow catfish, female and male fish are selected and raised separately; oxytocin is added to the feed for feeding for a period of time, and white light irradiation is increased at the same time, and in the later stage Add ovulation-stimulating agent; raise female fish and male fish mixedly, separate them into two parts with fishing nets, and raise all yellow catfish separately on the side of the water inlet of the pool, add ovulation agent to the water, and keep the running water flowing; keep the water temperature and adjust The acidity and alkalinity of the water, pump oxygen into the pool to wait for the eggs to be fertilized and hatched; after hatching, the fry should be properly raised, and then the feed for seedlings should be dissolved in water and introduced into the water for feeding, and an appropriate amount of white light irradiation should be provided. After 10‑20 days, different Larger fry are reared separately. The method provides a method capable of quickly carrying out artificial propagation operation and raising seedlings. The method can enable the yellow catfish to be artificially induced to spawn in a more natural state, and the operation is simple and convenient, and the reproduction effect is good.

Description

technical field [0001] The invention relates to the technical field of raising fish seedlings, in particular to a method for artificial propagation and seedling raising of yellow catfish. Background technique [0002] The yellow catfish belongs to the Siluriformes, the family Pleurotus, and the genus of the yellow catfish. It is a high-quality and valuable economic fish in freshwater waters. It is loved by people because of its delicious meat. Artificial culture of yellow catfish has been carried out in many parts of the country, and the scale of farming has increased year by year. In 2015, the cultured output of yellow catfish in my country exceeded 350,000 tons. Fry breeding of catfish and other Siluriformes is basically artificial induced labor, multiple injections of drugs, killing males and extracting sperm, and hatching in special hatching tanks; this leads to a serious imbalance in the ratio of males and females in natural waters, resulting in serious depletion of natu...
