Method for regulating and controlling water quality of pond for breeding Hikari Moyomono

Abstract

The invention provides a method for regulating and controlling the water quality of a pond for breeding Hikari Moyomono. The method comprises the steps: disinfecting the culture water body of the pond, putting Hikari Moyomono, performing feeding according to situations of food and activity of Hikari Moyomono and the season and weather conditions, changing the water in the pond regularly so as to ensure the dissolved oxygen content in the water body at a level not less than 4 mg / L, and adjusting the pH value of the water body so as to complete regulation of the water quality. Mass reproductionof endogenous microorganisms in the pond water body can be promoted through addition of molasses, inorganic nitrogen is assimilated through the endogenous microorganisms, ammonia nitrogen, nitrite nitrogen and other harmful nitrogen sources in the pond can be reduced, the water quality environment of the breeding pond can be improved, meanwhile, the water change cycle of the pond is prolonged, andwastewater discharge is reduced in the breeding process, so that pollution to the environment is reduced, growth of the Hikari Moyomono in the pond is facilitated, and serious harm to the bred HikariMoyomono is reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a water quality control method for cultivating patterned carps in ponds. Background technique [0002] Koi is also known as the "God Fish", which symbolizes auspiciousness and happiness. People regard koi as a work of art, known as "living gems" in the water, and have cultivated rare varieties with high ornamental value, such as macular, Taisho three-color, and Showa three-color, among which the patterned skin light carp is the most famous. Deeply loved by people, all koi produced by mating carp other than writing carp (carp in white writing or scarlet writing system) and golden carp can be called patterned skin light carp. [0003] At present, in high-density intensive aquaculture ponds, creating a good and stable water quality is the focus and difficulty of aquaculture piguang carp technology. However, during the entire breeding process, a large number of water changes an...

Problems solved by technology

However, during the entire breeding process, a large number of water changes and the addition of exogenous microecological agents are usually used to improve the water quality of the pond, but the effect is often not optimistic. Harmful substances such as ammonia nitrogen and nitrite nitrogen continue to accumulate in the pond. It will seriously harm the growth of Piguang carp in ponds, and cause serious harm to the breeding of Piguang carp in ponds
