Pearl shell factory-like recirculating aquaculture system and method

Abstract

The invention discloses a pearl shell factory-like recirculating aquaculture system and method. The culture system comprises two or more bait culture ponds, one or more shellfish culture ponds and a water return tank; each bait culture pond is communicated with the water return tank through a bait supply pipe, an inlet of the bait supply pipe is located on an upper water layer of the bait culturepond so that the upper water layer with abundant chlamydomonas bait can flow into the water return groove through the bait supply pipe; the water return tank is communicated with the shellfish cultureponds through bait separation pipes, a water pump is arranged in the water return tank and connected with inlets of the bait separation pipes, and after the bait separation pipes are bifurcated, outlets of the bait separation pipes are led into the shellfish culture ponds; the shellfish culture ponds are communicated through communicating pipes and communicated with the bait culture ponds throughwater return pipes; a blow-off pipe is further arranged at the bottom of each shellfish culture pond, and an outlet of each blow-off pipe is led out of the culture system. The culture system can ensure the sufficient and stable bait supply, the shell growth environment is controllable, and the culture operation is convenient.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a pearl oyster industrialized circulating water culture system and a culture method. Background technique [0002] Pearl oysters have a long history of breeding in my country. Because the pearls cultivated in the South China Sea are dignified and firm, round and clear, crystal clear and smooth, and their color lasts for a long time, they have long enjoyed a good reputation in the international market. One of the pillar industries in some coastal areas such as Guangxi and the South China Sea. Subsequently, due to the gradual increase in coastal pollution, aging farms, serious pests and diseases, and frequent natural disasters, the area of ​​pearl oyster cultivation is shrinking. The problem of high mortality in aquaculture has not been resolved, resulting in the almost disappearance of large-scale pearl mollusk culture in natural sea areas. The traditional offshore culture mode of pear...

Problems solved by technology

Subsequently, due to the gradual increase in coastal pollution, aging farms, serious pests and diseases, and frequent natural disasters, the area of ​​pearl oyster cultivation is shrinking. The problem of high mortality in aquaculture has not been resolved, resulting in the almost disappearance of large-scale pearl molluscs in natural sea areas

The traditional offshore culture mode of pearl oyster has been difficult to maintain its development, especially large pearl oysters such as pearl oyster, mother of pearl oyster and penguin oyster, which have extremely strict requirements on the culture environment and culture conditions

Due to the limitation of pearl oyster filter-feeding characteristics, the current subgrade pond culture mode is also difficult to maintain the normal growth and survival of pearl oysters for a long time. Therefore, a culture system that can maintain bait supply and a stable breeding environment for a long time is needed to meet the growth of pearl oysters. need
