Description

TECHNICAL FIELD

[0001] The present application relates to a culture pond, in particular to a raceway culture pond for collecting and discharging sewage, and belongs to the technical field of aquaculture. BACKGROUND

[0002] The raceway culture pond is a culture mode which combines the characteristics of high-level pond culture and factory-like intensive culture. A water partition wall is added in the middle of the culture pond, and a gap is left between the water partition wall and the pond wall. When water is introduced or oxygen is supplied, the water in the culture pond will flow around the water partition wall, and the static water becomes flowing water. Due to the flowing state, the raceway culture pond is named as such. The typical raceway culture pond is operated by circulating water, and requires high-density culture and circulating water operation. Therefore, a large amount of capital is needed to build infrastructure, increase biological safety, and build additional control tools. The raceway culture is high in density and high in water quality requirement, and needs a filtering system, microorganisms, siphon, temperature control, and high-quality feed, etc. The purpose is to provide a stable environment for the culture object and achieve efficient culture.

[0003] At present, the raceway culture pond is mainly used for white shrimp culture in South America. However, there are problems such as poor sewage collection effect, small sewage discharge amount, and heavy water pollution, which leads to low utilization rate of most raceway culture ponds in China, poor culture effect, and restricts the development of the raceway culture pond.
