Method for improving water quality of cyprinoid breeding pond

Abstract

The invention provides a method for improving water quality of a cyprinoid breeding pond, relates to a cyprinoid breeding method, and aims to solve the problems that in a water quality regulation and control process of some cyprinoid breeding ponds, due to change of a large amount of water, nutrient substances of the ponds are lost, the breeding cost is increased, breeding sewage severely pollutes a surrounding environment, and the water quality regulation and control effect of an added exogenous microbial ecological agent or other chemical water quality regulation and control agent is poor. The method comprises the following steps: firstly, arranging a micropore oxygenation device, enabling the micropore oxygenation device to run continuously before stocking of fishes, then adding a carbon source, and pushing the fishes in a suitable place to breed; secondly, adding the carbon source according to models; and thirdly, breeding, feeding the fishes with feed, and controlling dissolved oxygen in water. On the basis of no change of breeding water, methods of arranging the oxygenation device manually, controlling disturbance to bottom mud of the pond manually, manually adding carbohydrate and the like are used together, and therefore, harmful nitrogen sources including ammoniacal nitrogen, nitrite nitrogen and the like in the breeding pond are reduced. The method is used for improving the water quality of the cyprinoid breeding pond.

Description

technical field

[0001] The invention relates to a method for carp breeding. Background technique

[0002] In high-density intensive pond culture of carp, harmful substances such as ammonia nitrogen and nitrite nitrogen accumulate in large quantities, causing serious harm to farmed fish. At present, the methods for water quality control of carp culture ponds are mostly to improve the water quality of ponds by adding one or several exogenous microecological agents to the culture ponds, except for a large number of water changes. However, the results are often not optimistic, and sometimes even Seriously endanger the growth of pond cultured fish. In fact, no matter what kind of microecological preparations, they are just bacteria that need a specific living environment. Like other bacteria, they can only grow and reproduce normally in an environment that can meet their physiological characteristics, and can play their limited role. It is impossible for any probiotics to exert...
