Method for breeding Wuchang breams in ecological environmental protection mode

Abstract

The invention provides a method for breeding Wuchang breams in an ecological environmental protection mode. The method comprises the steps that a farm is built, wherein a three-dimensional farm is built; a recirculating aquaculture system is built in a base layer, wherein a breeding wastewater purification ecological ditch, a wastewater sedimentation tank and a purification tank are arranged on the base layer; the Wuchang breams are fed, wherein the feeding proportion is controlled according to the breeding date and the temperature of a breeding water source; daily management is conducted, wherein new water injection and oxygen aeration time is reasonably selected; disease control is conducted. According to the method, by building the three-dimensional farm, aquatic plants for feeding the Wuchang breams and the Wuchang breams are bred simultaneously, ecological environmental protection is achieved, and the breeding efficiency is improved; by arranging a natural fiber material layer on an aquatic plant breeding layer, the breeding water source is recycled through the recirculating aquaculture system, Wuchang bream metabolite which is conveyed into the aquatic plant breeding layer through the recirculating aquaculture system is decomposed to provide nutrition for growth of the aquatic plants, and the breeding cost is lowered.

Description

technical field [0001] The invention relates to the technical field of aquaculture. More specifically, the present invention relates to a method for cultivating Wuchang fish in an ecological and environment-friendly way with high efficiency and low cost for cultivating precious fish. Background technique [0002] Wuchang fish is warm in nature and sweet in taste; it has the effects of tonifying deficiency, nourishing the spleen, nourishing blood, dispelling wind, and invigorating the stomach; it has the effects of regulating viscera, appetizing spleen, and increasing appetite. It can inhibit the occurrence of diseases such as vascular sclerosis. Every 100 grams of Wuchang fish (edible part) contains 61 grams of water, 20.8 grams of protein, 15.8 grams of fat, 0.9 grams of carbohydrates, 229 kcal of calories, 15 grams of ash, 155 mg of calcium, 195 mg of phosphorus, 2.2 mg of iron, and Flavin (vitamin B12) 0.08 mg, niacin (niacin) 1.8 mg. [0003] Wuchang fish is one of th...

Problems solved by technology

However, the problems existing in the existing breeding technology are as follows: one is that the aquaculture wastewater is directly discharged to the water system adjacent to the farm, which pollutes the environment; the other is that it is discharged into the internal ditch system of the farm, which pollutes the aquaculture water, and the water quality management conditions are poor. , investing a lot of money in building artificial wetlands to breed Wuchang fish
