Industrialized freshwater pearl culture system

Abstract

The invention provides an industrialized freshwater pearl culture system. The system comprises culture units, a plurality of culture pools, a drainage and purification system, a water supply system, suspended fixing brackets, culture bag devices and lifting mechanisms; the culture pools are horizontally distributed on each culture unit, the lower portion of each culture pool is communicated with the drainage and purification system, the water supply system is communicated with the culture pools, the suspended fixing brackets are arranged above the culture units, the lifting mechanisms are arranged in the culture pools and matched with the culture bag devices, each lifting mechanism is provided with a first lifting mechanism and a second lifting mechanism which are connected with traction cables respectively, and the end portions of the traction cables are connected to the suspended fixing brackets; a good ecological environment for culturing shellfish and pearls is conveniently created, and the environmental pollution is reduced; by arranging two culture bag suspending units, the space is fully utilized, it is avoided that the density of pearl mussels is too high, and the survivalrate of the pearl mussels is increased.

Description

【Technical field】 [0001] The invention relates to the technical field of pearl cultivation, in particular to a factory freshwater pearl cultivation system. 【Background technique】 [0002] Pearl cultivation refers to the fact that according to the physiological function that pearl oysters can secrete nacre to form pearls, small pieces of cells or small pieces of pearl nuclei and small pieces of cells are implanted in the body of pearl oysters, and pearls are cultivated after a certain period of time. my country's freshwater pearl cultivation began in the early 1970s and has a history of more than 40 years. The main pearl-breeding mussel is Trigonopsis. my country's freshwater pearl production has accounted for about 90% of the world, and the cultivation area is also expanding year by year, mainly concentrated in Zhejiang. , Jiangsu, Hunan, Anhui and other places. At present, most of the local pearls are cultured in ponds, and there are few large-scale indoor cultures. Pond f...

AI Technical Summary

Problems solved by technology

Pond farming is limited by geographical conditions, and it is difficult for breeders to control water quality, water temperature, salinity, bait and other breeding indicators during the breeding process, and excessive fertilization can easily cause serious pollution to the water environment

As a result, on the one hand, the quality of the pearls produced is unstable, and the acquisition rate of high-end high-quality pearls and special pearls is low; on the other hand, a large number of rice fields are occupied, which increases the burden on agricultural production.
