Problems solved by technology

For example, some people try to use cage culture, but it is difficult to solve the contradiction of the migratory habits of salmon; some people try to use mountain spring water to breed, but they cannot solve the contradiction of salmon's low water temperature throughout the year
In addition, the difficulty of controlling the water quality of mountain springs and the serious deterioration of water quality caused by flash floods during the rainy season will endanger salmon farming
In addition to the above-mentioned problems, other breeding methods explored by people are also difficult to promote due to the constraints of natural conditions.

Embodiment Construction

[0044] 1. Water source and breeding environment:

[0045] Adopt pollution-free deep well water culture, and the depth of the well depends on the water quality. The water quality is required to be colorless, odorless, clear and transparent, with a pH value of 7-7.3. Referring to Figure 2 and Figure 3, according to the habit of salmon swimming against the water for a long time, the fish pond is designed to be circular, with uniform water flow and no dead ends, which is suitable for the living habits of salmon. There are two water injection ports in the fish pond, the lower water injection port 22 is 5-10 cm away from the bottom of the pool, and water is injected along the tangential direction of the pool wall. swirl. The upper water injection port 21 is located 1.5-2 meters away from the upper edge of the pool wall. The upper water injection port is duckbill-shaped and equipped with water spray holes. This water injection method can cause water to be ejected at a certain press...

Abstract

The present invention uses fresh water as farming environment, according to the basic requirement for growth of salmon the farming water source, water quality condition, stocking density and bait matching proportion are defined to make culture, at the same time the fish pond, subsider, filtering pool, refrigeration equipment, water pump and water collecting tank are formed into a semi-closed circulation farming system, and in the circulation the problems of discharging sewage, filtering and disinfection, temp. regulation, water supply and aeration also can be resolved.

Description

technical field [0001] The invention relates to a method and device for cultivating salmon, belonging to the technical field of agricultural breeding. Background technique [0002] Salmon is one of the world's most important economic fish resources. It is delicious in meat, rich in nutrition, large in size, and fast in growth and development. It is especially suitable for fresh food, and can also be frozen, canned, dried, pickled, smoked, etc. Studies have shown that salmon is rich in unsaturated fatty acids, such as: W-3, PHL, EPA and other components, which can effectively prevent cardiovascular and cerebrovascular diseases. American scientists have proved through experiments that if you eat 50 grams of salmon every day, the incidence of cardiovascular and cerebrovascular diseases can be reduced by 50%, which shows that its therapeutic effect is good. Salmon is a cold-water migratory fish. Because the 12-degree isothermal line in the northern hemisphere ends in the centra...
