Method for separate type artificial breeding of salmon

Abstract

The invention provides a separated artificial salmon breeding method. The separated artificial salmon breeding method comprises the steps that a breeding farm is established, wherein the separated stereo breeding farm is established; a recirculating aquaculture system is established on a bottom layer; salmon breeding is performed, wherein aquatic insects or bait fish bred on a top layer are fed into the bottom layer, wherein the feeding proportion is controlled according to feeding date and the temperature of an aquaculture water source; daily management is performed, wherein fresh water and oxygen increase time are reasonably selected; diseases are prevented and controlled. Salmons which do not reach the marketing specifications and salmons which reach the marketing specifications are bred by establishing the separated stereo breeding farm in a separated mode, the little fish growth speed is improved, ecological environmental protection is achieved by simultaneously breeding the aquatic insects or bait fish and the salmons, the breeding efficiency is improved, the aquaculture water source is recycled through the recirculating aquaculture system, the aquaculture cost is reduced, and accurate control of salmon breeding environment temperature is ensured by arranging a heat-insulation system.

Description

technical field [0001] The invention relates to the technical field of aquaculture. More specifically, the present invention relates to a method for the isolated, high-efficiency, and low-cost artificial farming of salmon that is a valuable fish. Background technique [0002] Salmon is a valuable large-scale economic fish. Large and fat, with delicious meat, salmon is not only a large and precious specialty fish in Heilongjiang Province, but also one of the rare freshwater fish in my country. Its meat is delicate, red in color, delicious, rich in fat and high in nutritional value. Containing 14.9-17.5% protein, 8.7-17.8% fat, 61.4% water, 1384 calories per 100 grams, 50 mg calcium, 153 mg phosphorus, and 1.9 mg iron. In addition, it also contains carbohydrates and multivitamins. Its eggs are crystal clear and translucent, and the grains are like pearls. They are rich in phosphate, calcium, and vitamins A and D. They are recognized as a feast meal and have the functions o...

Problems solved by technology

However, at present, artificial breeding of salmon does not adopt a separate farming method, resulting in the crowding of salmon that has not reached the market size and the salmon that has reached the market size in the same growth space, slowing down the growth rate and reducing the breeding efficiency; In addition, salmon

Many of the current salmon farming methods can not control the temperature of the water body in the breeding pond very well, and the accidents of the whole army of salmon caused by improper temperature control are not uncommon, which has caused huge economic losses to the farmers; in addition , there is also the phenomenon that the aquaculture wastewater is directly discharged to the water system adjacent to the farm, polluting the environment; discharged to the internal ditch system of the farm, polluting the aquaculture water, poor water quality management conditions, resulting in a large number of salmon deaths
