Harmless culture method of freshwater pearls

Abstract

The invention discloses a harmless culture method of freshwater pearls and belongs to the field of freshwater pearl culture. The harmless culture method of the freshwater pearls includes establishment of culture ecology, wherein a pearl breeding mussel culture pond, an original aquaculture pond and a water purification pond which are isolated from one another are constructed; the pearl breeding mussel culture pond is divided into a young mussel culture pond and an adult mussel culture pond; an annular circular culture system communicated by a circulating pump is formed by establishing the young mussel culture pond, the adult mussel culture pond, the original aquaculture pond and the water purification pond which are isolated from one another; water in different culture ponds is separately utilized, and the fully utilized water is introduced into the water purification pond for electrolysis and filtration treatment, so that the content of nitrogen, nitrate nitrogen and harmful substances in the water is effectively reduced, and wastewater is converted into raw materials; the treated raw materials are circularly introduced into the culture ponds at all levels, so that not only is the water of the whole culture system purified, but also the cost is reduced, and the environmental pollution degree is lowered.

Description

technical field [0001] The invention relates to the field of freshwater pearl cultivation, in particular to a method for harmless cultivation of freshwater pearls. Background technique [0002] With the continuous expansion of the pearl farming industry, my country's pearl production has also continued to increase. It reached its peak in the past few years, with an annual output of more than 4,000 tons. my country has also become the world's largest producer of freshwater pearls. Later, due to excessive pearl production and improper breeding management, the pearl production began to decline. And there are many problems brought about by pearl cultivation, such as: disease, water pollution, poor quality pearls and so on. [0003] Among them, water pollution has become a hot topic in the current society. Due to the excessive use of fertilizers and bait in the water during breeding, water quality pollution and damage to the water body have been caused. Environmental pollution h...

Problems solved by technology

Later, due to the excessive production of pearls and improper breeding management, the production of pearls began to decline.

And there are many problems brought about by pearl farming, such as: disease, water pollution, poor pearl quality, etc.

[0003] Among them, water pollution has become a hot topic in the current society. Due to the excessive use of fertilizers and bait in the water during breeding, water quality pollution and damage to the water body have been caused. Environmental pollution has also forced relevant policies in many places to suppress and reduce the breeding area. Lead to the decline of the pearl industry, which also brings bad economic benefits to the farmers of pearl mussels
