Problems solved by technology

[0004] However, in the breeding process of sturgeon, there are some problems, mainly including disease prevention and control, feed and nutrition and drug residues.
Now our country's sturgeons are relatively prone to outbreaks of some fatal and contagious comprehensive diseases from egg hatching, fish fingerling cultivation to commercial fish farming, and once the disease occurs, it is very difficult to treat; from the feed used in sturgeon farming From the point of view, the existing problems are: containing hormones, insufficient ripening, substituting low-quality fish meal for high-quality fish meal, high fat content, etc.

Embodiment 1

[0021] The sturgeon culture method of the present invention comprises the following steps:

[0022] (1) Breeding pond treatment: inject 0.8m of clear water into the culture pond, control the water temperature at 18-25°C, disinfect the culture pond with potassium permanganate, the dosage of potassium permanganate is 10g / m3, and the disinfection time is 2 days. Light up all the water in the breeding pond, then inject clean water to a height of 0.8m, and turn on the aerator to aerate and increase oxygen to keep the dissolved oxygen in the water above 4ml / L, and wait for the seedlings to be released;

[0023] (2) Sturgeon fry: select appearance without damage, no deformity Sturgeon fry, seed size is 8-12cm, stocking density is 40 / m3, fry with 5% concentration of salt water before putting into the breeding pond Soak in the bath for 5 minutes;

[0024] (3) Scientific feeding: adopt batches to regularly put in self-made feed, and oxygenate the pool water 20-25min before and after ea...

Embodiment 2

[0027] The sturgeon culture method of the present invention comprises the following steps:

[0028] (1) Breeding pond treatment: inject 1m of clear water into the breeding pond, control the water temperature at 18-25°C, disinfect the breeding pond with potassium permanganate, the dosage of potassium permanganate is 8g / m3, and the disinfection time is 3 days. Light up all the water in the pool, then inject clean water to the pool height of 0.8m, and turn on the aerator to aerate and increase oxygen to keep the dissolved oxygen in the water above 4ml / L, and wait for the seedlings to be released;

[0029] (2) Sturgeon seedlings are put in: select the sturgeon frylings with no damage on the appearance and no deformities, the seedling size is 8-12cm, and the stocking density is 30 / m3, and the saltwater of 3% concentration is used before the seedlings are put into the breeding pond Soak in the bath for 10 minutes;

[0030] (3) Scientific feeding: adopt batches to regularly put in s...

[0033] The sturgeon culture method of the present invention comprises the following steps:

[0034] (1) Breeding pond treatment: inject 0.8m of clear water into the culture pond, control the water temperature at 18-25°C, disinfect the culture pond with potassium permanganate, the dosage of potassium permanganate is 10g / m3, and the disinfection time is 2 days. Light up all the water in the breeding pond, and then inject clean water to the height of the pond to 0.6m, and turn on the aerator to aerate and increase oxygen to keep the dissolved oxygen in the water above 4ml / L, and wait for the seedlings to be released;

[0035] (2) Sturgeon fry: select appearance without damage, without deformity Sturgeon fry, seed size is 8-12cm, stocking density is 40 / m3, before the fry are put into the culture pond, use 4% concentration of salt water Soak in the bath for 10 minutes;

[0036] (3) Scientific feeding: adopt batches of self-made feeds to be fed at regular intervals, oxygenate the p...

Abstract

The invention discloses a sturgeon aquaculture method. The method specifically comprises steps as follows: (1) culture pond treatment: a culture pond is disinfected with potassium permanganate, waterin the culture pond is completely drained after disinfection, and clear water is injected to keep the dissolved oxygen in water being 4 ml / L or above; (2) adding of sturgeon fries: 8-12 cm of fries are selected, and the stocking density is 30-40 fries / m<3>; (3) scientific feeding: self-made feed is added at fixed time in different batches, and the feeding amount is 3%-5% of the total weight of fishes; (4) disease control. According to the systematic and efficient sturgeon aquaculture method, the steps of culture pond treatment, adding of the sturgeon fries, scientific feeding and disease control are adopted, the feeding efficiency is notably improved, and diseases and pests are reduced.

Description

technical field [0001] The invention belongs to the field of animal husbandry breeding, and in particular relates to a scientific and systematic sturgeon breeding method. Background technique [0002] Sturgeon is a large and medium-sized economic fish. It originated from the ancient bony fish 200 million years ago. It is one of the oldest fishes in existence. There are 26 species in total, and there are 8 species in my country. Sturgeon has high nutritional value. Sturgeon meat and eggs are delicious, especially caviar, which is known as "black gold". According to the records in "Compendium of Materia Medica", sturgeon meat and internal organs have medicinal value, and its cartilage has anti-cancer factors, and has the effects of beautifying and delaying aging. Sturgeon skin is the raw material for making high-grade leather. [0003] Sturgeons are highly adaptable and grow rapidly. Breeding species mainly include: Siberian sturgeon, Russian sturgeon, sterlet sturgeon, Stu...
