Micropterus salmonides aquaculture system and aquaculture method

Abstract

The invention provides a Micropterus salmonides aquaculture system and aquaculture method. The system comprises a pond, a sewage collection well and a water circulation device; the bottom of the pondis connected with the sewage collection well through a sewage discharging pipe; the sewage collection well is composed of a main well and an auxiliary well; the auxiliary well is located at one side of the main well; the bottom of the auxiliary well is provided with a drain pipe; an isolation filter layer is arranged on the top of the main well; a manure outlet is arranged at the bottom of the main well; the manure outlet is connected with the auxiliary well through a manure outgoing pipe; the tail end of the manure outgoing pipe is higher than the manure outlet at the bottom of the main well;the outlet end of the sewage discharging pipe is connected with a gas exhaust pipe and an auxiliary water outgoing pipe, wherein the gas exhaust pipe and the auxiliary water outgoing pipe have upwards-facing openings; the air exhaust opening of the air exhaust pipe is higher than the isolation filter layer; one side of the lower end portion of the gas exhaust pipe is connected with a main water outgoing pipe; the auxiliary water outgoing pipe is communicated with the auxiliary well; a long pipe is inserted into the opening of the auxiliary water outgoing pipe; the water circulation device includes a pond water pipe, a sewage collection well water pump, a sewage collection well water pipe, a circulating water pump, a microbial treatment tank, and a return pipe; water in the pond and the sewage collection well is pumped to the microbial treatment tank; the water is treated; the treated water is returned to the pond; and therefore, the problem of the discharge of aquaculture wastewater can be solved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an ecologically healthy and efficient California perch farming system and method. Background technique [0002] California perch, scientifically known as largemouth bass, is native to the Mississippi River system in California, USA, and is a rare carnivorous fish. It is welcomed by the market because of its delicious meat, strong disease resistance, rapid growth and easy catch. The domestic market demand for California sea bass is huge. It is understood that Guangdong, Zhejiang, Sichuan, and Guizhou in China have aquaculture, and the annual market demand remains above 350,000 tons. [0003] The Pearl River Delta region of Guangdong Province is the area with the highest breeding volume of California perch. Since 2016, the annual output can reach more than 150,000 tons. At present, the cultivation of California perch in the Pearl River Delta region is mainly based on earthen p...

Problems solved by technology

[0004] The present invention proposes an ecologically healthy and efficient culture system and method for California perch. The culture system forms a water treatment system and a shading net based on a central sewage collection and a biological filter through effective transformation of a traditional earthen pond, reducing the Discharge of breeding sewage, and at the same time solve the problems of high disease incidence and low feeding rate of California perch in high temperature period
