Problems solved by technology

However, in the past 20-30 years, due to overfishing, environmental pollution, and resource decline, the output of red bream has dropped sharply, resulting in a sharp decline in natural resources, and a contradiction between supply and demand has emerged, prompting red bream to go to artificial breeding.
Because the red chrysalis is used to growing and multiplying naturally in major water systems, and the artificial domestication technology of the red chrysalis in the prior art has not been able to break through, coupled with the irritable temperament of the red chrysalis, so it is in artificial breeding. The death rate of the red chrysalis is relatively high, and the survival rate is low, and the breeding cost of the red chrysalis is correspondingly increased. Therefore, the artificial breeding of the red chrysalis has not been promoted on a large scale.

Embodiment 1

[0024] A kind of artificial breeding method of cocked-billed red carp, the method comprises the following steps:

[0025] Step 1. Preparation before stocking

[0026] Clean the pond and disinfect the culture pond before stocking the fish fry of the red scalloped scallop: When the pond is dry, use methylene blue and salt to disinfect the pond for the first time, and water will start to enter the dry pond 11 days after disinfection; When the depth of the pond in the culture pond was 0.85m, the mixture of Chinese medicinal water and pond water was used to disinfect the cultivation pond again. The weights of Astragalus membranaceus, Yinqiao and carboxymethyl cellulose used in rice pool water are 3.5g, 4.5g, and 24g respectively; finally, the culture pond is fed to a depth of 1.8m, and 210kg / mu of base fertilizer is applied to the culture pond, and controlled The dissolved oxygen in the culture pond is higher than 7mg / L, the nitrite is lower than 0.5mg / L, the ammonia nitrogen is l...

Embodiment 2

[0037] A kind of artificial breeding method of cocked-billed red carp, the method comprises the following steps:

[0038] Step 1. Preparation before stocking

[0039] Clean the pond and disinfect the culture pond before stocking the red bream fish fry: when the pond is dry, use methylene blue and salt to carry out the initial disinfection treatment on the culture pond, and water will start to enter the dry pond 14 days after disinfection; When the pond depth of culture pond is 0.9m, adopt the mixed solution of Chinese medicine water and pond water to carry out disinfection treatment again to culture pond, described Chinese medicine water is the boiled liquid of Radix Astragali, Yinqiao and carboxymethyl cellulose, and every cubic meter The weights of Astragalus membranaceus, Yinqiao and carboxymethyl cellulose used in the pool water are 3.5g, 4.5g, and 24g respectively; finally, the water in the breeding pond is 2.3m deep, and 230kg / mu of base fertilizer is applied to the bree...

Abstract

The invention discloses an artificial breeding method for erythroculter ilishaeformis and belongs to the technical field of aquaculturing. In the artificial breeding method for erythroculter ilishaeformis, natural stocking of erythroculter ilishaeformis can be gradually changed into artificial breeding through controls on feeding to the erythroculter ilishaeformis of each domestication stage during the growth of the erythroculter ilishaeformis. The breeding method comprises twice disinfection of the culturing pond before the erythroculter ilishaeformis is placed in a culturing pond. During the domestication and culturing, various feeding methods and fodders are employed for the erythroculter ilishaeformis during each growth phases according to life habits of the erythroculter ilishaeformis and digestive physiology of the same, so the erythroculter ilishaeformis can be domesticated. The method is suitable for artificial breeding for erythroculter ilishaeformis.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a method for artificially rearing red carp with cocked mouth. Background technique [0002] Erythroculter ilishaeformis, which belongs to Cyprinidae, Cyprinidae, Erythroculter subfamily, Erythroculter genus, is commonly known as white fish and Diaozi fish. Because of its advantages such as large size, fast growth, excellent meat quality, delicious taste, and high economic value, it is deeply favored by consumers. The cocked-billed red bream is distributed in major water systems across the country, and has a large natural output, occupying a certain position in the history of fishery in our country. However, in the past 20-30 years, due to overfishing, environmental pollution, and resource decline, the output of red bream has dropped sharply, resulting in a sharp decline in natural resources, and a contradiction between supply and demand has emerged, prompting red bream to go t...
