Description

Technical Field

[0001] The present invention relates to the technical field of multi-layer circulating water culture systems for babylonia conch, and in particular to a multi-layer circulating water culture system for babylonia conch and a method for using the system. Background Art

[0002] Dongfeng conch inhabits the sea area with muddy bottom in the subtidal zone. It is a benthic snail with delicious meat and rich nutrition. It is deeply loved by consumers and is a precious marine delicacy with high economic value. Since the production of mud conch in natural sea areas is limited and cannot meet the vast market demand, professional Dongfeng conch breeding equipment has emerged to carry out large-scale artificial breeding. During the breeding process, food residues and Dongfeng conch excretions will be directly discharged into the sand layer. After decomposition, it will produce a mixture of nitrogen and phosphorus, causing the sand layer to turn black and the pool water to be polluted, and the cleaning of breeding pollutants is very difficult. In particular, long-term pollution accumulation or high-density breeding will bring serious disease problems to the breeding of Dongfeng conch, which is also an important influencing factor for the occurrence of diseases and low survival rate in Dongfeng conch breeding.

Residual bait, excrement, etc. will continue to accumulate in the sand layer, causing the sand layer to deteriorate and blacken, causing the appetite of Babylonia spotted worms to decrease, resulting in slow growth and frequent diseases, and the problems of high intensity of water replacement and residue cleaning work in the cultivation pool, low production efficiency, etc., and may cause mechanical damage to Babylonia spotted worms, promoting the occurrence of diseases.

A connecting regulating valve is arranged in the middle of the connecting section for adjusting the switch and flow control of the connecting section. The discharge section is connected to the sewage discharge valve group 143. The sewage collection and drainage pipe 142 is designed to control the liquid level in the aquaculture box.
