Freshwater Pearl Culture System

Abstract

The invention discloses a fresh water pearl culturing system, comprising a culture pond body, a purifier, a first water pipe, a second water pipe, an air compressor, and a first air pipe. The purifier comprises a housing, a holding space is formed in the housing, one end of the housing is provided with a first water inlet, and the other end is provided with a first water outlet, and the housing is internally provided with two baffles at interval. The two baffles divide the holding space into a first cavity, a second cavity, and a third cavity. Both of the two baffles are formed by an upper part and a lower part. The upper part is provided with a plurality of first holes. One end of the first water pipe is arranged on the lower part of the culture pond body, and the other end is communicated with the first water inlet. One end of the second water pipe is communicated with the first water outlet, and the other end is arranged on the upper part of the culture pond body. One end of the first air pipe is connected with the air outlet of the air compressor, and the other end is arranged on the lower part of the culture pond body. The system improves water quality in the culture pond, and provides good environment for growth of clams, thereby being beneficial for improving yield of pearl.

Description

technical field [0001] The invention relates to a cultivation system, in particular to a freshwater pearl cultivation system. Background technique [0002] China is a big aquaculture country in the world. The aquaculture volume accounts for more than 65% of the world's total. There are many varieties, a wide range, and high output. The aquaculture area is also expanding with the increase in demand. Pearl is an ancient organic gemstone, mainly produced in pearl shellfish and mother-of-pearl shellfish molluscs. Pearl is not only an ornament, but also a precious traditional medicinal material, which has high use value and wide market demand. [0003] Artificially cultured pearls have a long history in our country. They are mainly hung in natural waters such as rivers and lakes, or in natural and artificially dug ponds. Usually, a small amount of carnivorous fish are mixed in the water, and organic fertilizers are sprinkled into the water. or chemical fertilizers to cultivate ...

Problems solved by technology

However, the extensive use of organic fertilizers or chemical fertilizers can easily lead to eutrophication of the water body. A large amount of fish feces and leftover bait residues are deposited at the bottom of the water body, resulting in the continuous accumulation of organic matter at the bottom of the water body, which is easy to ferment and produce carbon dioxide, resulting in severe hypoxia in the water body. Imbalance, easy to cause low pearl production and even lead to the death of pearl oysters

Direct discharge of polluted water can easily cause environmental pollution and even threaten human health
