A kind of California perch culture system and culture method

Abstract

The present invention proposes a California perch culture system and method. The system includes a pond, a sewage collection well and a water circulation device. The bottom of the pond is connected with a sewage pipe leading to the sewage collection well. There is a drainage pipe on one side and the bottom of the main well, an isolation filter layer on the top of the main well, and a manure outlet on the bottom. The manure outlet is connected to a manure pipe leading to the auxiliary well, and the end outlet of the manure pipe is higher than the main The excrement outlet at the bottom of the well; the outlet end of the sewage pipe is respectively connected with an upward-opening exhaust pipe and an auxiliary water outlet pipe. The water outlet pipe and the auxiliary water outlet pipe are connected to the auxiliary well, and the opening of the auxiliary water outlet pipe is inserted with a long 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, and the pond water The water from Heji sewage well is pumped to the microbial treatment tank for treatment and then returned to the pond, which solves the problem of the discharge of aquaculture sewage.

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
