Problems solved by technology

[0003] Nowadays, the aquaculture industry of sturgeon is growing day by day, and the methods of aquaculture are becoming more and more diversified. In the process of aquaculture, sturgeons are affected by pathogenic bacteria, temperature, dissolved oxygen, water quality, salinity, breeding density and feed, etc. Due to the influence of many factors, there are certain requirements for the growth environment. The traditional breeding method, the growth of sturgeon is relatively slow, and the input of manpower and material resources is high, the economic benefit is low, and the sturgeon is prone to disease during the breeding process. If it is controlled in time, it may lead to large-scale infection, which will cause economic losses to farmers; and the artificial breeding of sturgeon, the feed source is mainly imported feed, and the price is relatively high; some domestic enterprises have also begun to produce special aquatic compound feed. But it is far from meeting the needs of sturgeon growth, and the feed utilization rate is poor, the waste of resources is great, and even seriously pollutes the environment

Embodiment 1

[0029] (1) Fish pond treatment: Disinfect the fish pond with disinfectant, change the water after 3-5 days, and dry it for 1 day;

[0030] (2) Throw in fish species: in the fish pond after the fish species is put into step (1) treatment, control the water level in the pond to be 1m;

[0031] (3) Water temperature control: the water temperature is controlled at 20°C before putting in the breeding, and the water temperature is lowered by 1°C every other day after the fish species are put in, until the temperature drops to 12°C and remains unchanged;

[0032] (4) Feeding: put in fish fingerlings, put in chopped earthworms, and the daily input amount is 2% of the weight of the input fish fingerlings. After 22 days, change to throw in sturgeon feed until commercial fish are grown.

Abstract

The invention belongs to the culture technical field, and especially relates to a sturgeon culture method comprising the following steps: fishpond treatment, inputting fish fingerling, water temperature control, and feeding; the method is simple, low in cost, can promote sturgeon growth, and improve sturgeon output, can improve sturgeon immunity, and can increase pathogen resistant ability, thus providing favorable conditions for sturgeon growth.

Description

technical field [0001] The invention belongs to the technical field of cultivation, in particular to a method for cultivating sturgeon. Background technique [0002] Sturgeon, known as squid in ancient times, belongs to the chordate phylum, with a body length of 0.5-7 meters. It is the oldest fish with a large body, a long lifespan, and a history of more than 200 million years. History, originated in the Cretaceous period hundreds of millions of years ago, is known as the "water panda" and "water living fossil". , delicious meat, soft bones, high nutritional value, the protein content of sturgeon meat and eggs can be as high as 18% and 29%, based on the 25% seed yield of female sturgeon, the fish body still accounts for more than 75%, and the processing potential is huge Small packaged smoked products, grilled fish fillets, fried fish floss, sauced fish liver, smoked and grilled fish sausages processed from sturgeon meat are very popular in the international market. There ...
