Environmentally-restorable fresh water pearl mussel aquaculture based water conservation fishery method

Abstract

The invention belongs to the technical field of fresh water pearl mussel aquaculture and discloses an environmentally-restorable fresh water pearl mussel aquaculture based water conservation fishery method which involves an aquaculture pond for pearl mussel aquaculture. A balance biogroup is released in the aquaculture pond which is partitioned into a balance area and a static aquaculture area bya partition net in the aquaculture pond. Directional fertilization and sampling integrated rods are released into the aquaculture pond. By release of the balance biogroup into the aquaculture pond tobalance a fresh water pearl mussel aquaculture water environment of the aquaculture pond, growth of fresh water pearl mussels and pearls is promoted, fertilizing quantity reduction, aquaculture cost reduction and effective improvement of water quality are realized under identical conditions. In addition, by arrangement of the partition net for separation the balance biogroup and the pearl mussels,the directional fertilization and sampling integrated rods are used for feeding the pearl mussels, the balance biogroup and the pearl mussels are prevented from scrambling for feed, pearl mussel feedconsumption is reduced, and aquaculture cost is saved.

Description

technical field [0001] The invention relates to the field of freshwater pearl mussel culture, and more specifically, relates to a water conservation fishery method based on environment-restorable freshwater pearl mussel culture. Background technique [0002] Pearl is not only a noble ornament, but also a valuable traditional Chinese medicinal material, which has a high market value. With the development of social economy and scientific and technological level, the use of pearls has been continuously expanded, and the market demand is increasing. [0003] Artificially cultivated freshwater pearls have a long history in my country. At present, the species of pearl mussels used to cultivate freshwater pearls in my country are mainly triangular sail mussels. There are two main breeding modes for freshwater pearls: (1) Pearls that have undergone surgical insertion or core insertion are suspended in natural waters such as rivers and lakes. Mussels, cultivate phytoplankton as the ...

AI Technical Summary

Problems solved by technology

Mussel disease has become a chronic disease in freshwater pearl culture. The occurrence of mussel disease has caused huge economic losses to the production of freshwater pearl culture and greatly increased the risk of the freshwater pearl industry.

[0006] At present, the cultivation of domestic freshwater pearls usually requires the use of a large amount of organic fertilizers to fertilize the water quality and provide bait for pearl mussels. However, this process has the following shortcomings: (1) It causes a large amount of organic matter to be deposited on the bottom of the water, which is easy to breed bacteria and cause frequent occurrence of pearl mussel diseases. (2) After a large amount of organic matter is input into the water body, it will also consume oxygen and deteriorate the water quality, which is unfavorable for the growth of pearl mussels and pearls; (3) long-term large-scale application of organic fertilizers will make the permanganate index CODMn and total phosphorus TP of the water body Equally high, it is easy to break out Microcystis blooms, and the discharge of these aquaculture waters will often cause re-pollution of the surrounding environment
