Problems solved by technology

Although the technology of this breeding method is relatively mature, during the growth process of the sturgeon, the leftover bait and excrement of the sturgeon accumulate in the pond, destroying the water quality of the breeding pond and affecting the environment required for the growth of the sturgeon. Moss will be produced, and only the constant flow of water through the pump will cause a great waste of water and power resources, as well as an increase in labor costs, which will eventually lead to high cost of commercial sturgeon farming and lack of competitiveness
[0003] The existing methods of breeding sturgeon are relatively complicated, especially the feeding of bait is inconvenient, and the dispersion of bait is poor when feeding. Sturgeons need to concentrate in a certain narrow area to eat, which is not good for feeding
[0004] Therefore, the existing sturgeon farming method needs to be further improved

Embodiment 1

[0062] A method for cultivating sturgeon, comprising the steps of:

[0063] A. Breeding pond treatment: inject 1 meter of reservoir water into the pond, control the water temperature at 18-20°C, and disinfect the pond with potassium permanganate. The dosage of potassium permanganate is 8 grams per cubic meter of water, and the disinfection time is 48 hours. ; After disinfection, light up all the water in the breeding pond, re-inject reservoir water to a height of 1 meter, and at the same time turn on the aerator to aerate and increase oxygen. The dissolved oxygen in the water should be kept above 4ml / L, and wait for the seedlings to be released;

[0064] B, Sturgeon fry are put in: select the appearance without damage, without deformity Sturgeon fry, seed size is 8-12 centimeters; The stocking density is 30 per cubic meter; Before the fry are put into the culture pond, use 3% concentration Soak in salt water for 5 minutes;

[0065] C, scientific feeding: adopt feed feeding de...

Embodiment 2

[0068] A method for cultivating sturgeon, comprising the steps of:

[0069] A. Breeding pond treatment: inject 1 meter of reservoir water into the breeding pond, control the water temperature at 25-28°C, and disinfect the breeding pond with potassium permanganate. The dosage of potassium permanganate is 10 grams per cubic meter of water body, and the disinfection time is 48 hours. ; After disinfection, light up all the water in the breeding pond, re-inject reservoir water to a height of 1 meter, and at the same time turn on the aerator to aerate and increase oxygen. The dissolved oxygen in the water should be kept above 4ml / L, and wait for the seedlings to be released;

[0070] B, Sturgeon fry are put in: select appearance without damage, without deformity Sturgeon fry, seed size is 8-12 centimetres; The stocking density is 40 per cubic meter; Before the fry are put into the breeding pond, use 5% concentration Soak in salt water for 10 minutes;

[0071]C, scientific feeding: ...

Embodiment 3

[0074] A method for cultivating sturgeon, comprising the steps of:

[0075] A. Breeding pond treatment: inject 1 meter of reservoir water into the breeding pond, control the water temperature at 23-25°C, and disinfect the breeding pond with potassium permanganate. The dosage of potassium permanganate is 9 grams per cubic meter of water body, and the disinfection time is 48 hours. ; After disinfection, light up all the water in the breeding pond, re-inject reservoir water to a height of 1 meter, and at the same time turn on the aerator to aerate and increase oxygen. The dissolved oxygen in the water should be kept above 4ml / L, and wait for the seedlings to be released;

[0076] B, Sturgeon fry are put in: select appearance without damage, without deformity Sturgeon fry, seed size is 8-12 centimeters; Stocking density is 35 per cubic meter; Before fry is put into breeding pond, use 4% concentration Soak in salt water for 8 minutes;

[0077] C, scientific feeding: adopt feed fee...

Abstract

The invention discloses a sturgeon breeding method, which is characterized in that it comprises the following steps: A, treating a breeding pond; B, feeding sturgeon seedlings; C, scientifically feeding; D, adjusting water quality. The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a method for cultivating sturgeons that can improve the survival rate, reduce the cost of cultivating sturgeons, facilitate feeding, have good dispersion of bait, and facilitate the feeding of the sturgeons.

Description

technical field [0001] The invention relates to a method for cultivating sturgeon. Background technique [0002] Sturgeon is a cold-water fish with fast growth and tender meat. It is one of the special aquatic products with better economic benefits. At present, the main method of breeding sturgeon in East China is greenhouse constant-flow aquaculture. This method is to raise sturgeon at high density in square cement breeding ponds under the sunshade greenhouse. Generally, the size of the square pool is 8-10 meters long, 8-10 meters wide, and 1 meter high. PVC pipes are used for aeration in the pool, and a sewage outlet is designed at the bottom of the pool. In the breeding process, the breeding density of adult fish is generally controlled at 15-20 fish per square meter. The aerator must supply oxygen 24 hours a day. At the same time, the water pump continuously pumps water from deep underground wells or the lower layer of the reservoir for constant flow operation, so as to...
