Problems solved by technology

Therefore, the water source for cultivating cold-water fish needs clear micro-flowing water, which is not turbid or polluted. The annual water temperature changes within the range of 5-20 degrees, and the annual average water temperature is 8-15 degrees. The ambient water temperature is between 20 and 30 degrees. At present, the growth environment of cold-water fish and

Abstract

The invention discloses a nested culture method for cold water fishes and normal-temperature fishes. The method comprises a culture pond, the culture pond is internally provided with a cold water area, a heating bin and a normal temperature area in the horizontal direction, the culture pond is provided with a moving area and an excrement area in the vertical direction, the heating bin is internally provided with a heating plate, and one side of the culture pond is provided with a cooling purification pond. A main flow pipeline is fixedly installed at one end of the cooling purification pond, a booster pump is fixedly installed on the main flow pipeline, a water inlet spray head is fixedly installed at the output end of the booster pump and located on one side of the cold water area, and a transfer collecting barrel is connected to the side, located on the normal temperature area, of the culture pond. A filtering plate is fixedly installed at the central position in the transfer collecting barrel. A sealing cover plate matched with the filtering plate is hinged to the transfer collecting barrel. In the using process, cold water fish and normal-temperature fish nested breeding is adopted, water resources are saved, control is convenient, and the survival rate of the cold water fishes and the normal-temperature fishes is increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a nested culture method for cold-water fish and normal-temperature fish. Background technique [0002] Cold-water fish like to inhabit mountain streams with clear water, gravel bottom, and sufficient dissolved oxygen. The growth limit temperature of adult fish is 0-30 degrees, the suitable growth temperature is 12-20 degrees, and the optimum growth temperature is 16-18 degrees. In the suitable temperature range, the food intake is vigorous, the growth is rapid, and the body maintains a good metabolic state. Below 8 degrees or above 20 degrees, loss of appetite and slow growth. If it exceeds 24 degrees, feeding stops, the body fails and even dies. 27-30 degrees, short time. Therefore, the water source for cultivating cold-water fish needs clear micro-flowing water, which is not turbid or polluted. The annual water temperature changes within the range of 5-20 degrees, and t...
