Weever breeding device and method

Abstract

The invention discloses a weever breeding device and method. The weever breeding device comprises breeding pond bodies, the breeding pond bodies are evenly distributed, a crawling ladder is fixedly installed in the middle of each breeding pond body, a horizontally-distributed filtering plate is fixedly installed in each breeding pond body, and each breeding pond body and the crawling ladder form an integral breeding environment; a water channel circulation framework and an oxygen supply framework are arranged in the integral breeding environment, and a greenhouse body is arranged outside the integral breeding environment; a safety door is arranged on the outer wall of one side of the greenhouse body; and the water channel circulation framework is composed of annular water channels, a centrifugal pump body, a water suction pump body and a sewage suction pipeline, the annular water channels are located at the upper end of the interior of the breeding pond body, and the annular water channels are fixedly connected through second connecting water channels. In the using process, water quality and temperature information in the breeding environment can be detected in real time, the stability of the breeding environment is maintained, and the breeding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a culture device and method for perch. Background technique [0002] Perch (Lateolabrax japonicus), also known as flower perch, Zhaihua, perch board, four-rib fish, etc., is commonly known as perch, and is listed as "China's four famous freshwater fish" together with Yellow River carp, mandarin fish and Heilongjiang Xingkai Lake big white fish. my country's perch species are mainly Songjiang perch, also known as four-gill perch, also known as tiger head fish. It is a migratory fish in cold and temperate sea and freshwater. It is small in size, with a body length of about 100mm. Growing and fattening in fresh water, inhabiting the bottom of clear flowing water, lurking during the day and active at night, preying on shrimps and small fish. When managing the pond breeding environment, it is necessary to do a good job of sludge discharge at the bottom of the pond. With the cont...

Problems solved by technology

With the continuation of the perch breeding time, a large amount of harmful substances are easy to accumulate at the bottom of the fish pond. The existence of such substances will cause water pollution, and will also lead to the spread of various diseases, bringing the risk of dead fish to California perch farming.

To solve such problems, it should be realized by constructing a sewage self-overflow system at the bottom of the fish pond to discharge the aquaculture sediment at the bottom of the fish pond. During the cleaning process, a lot of manpower and material resources will be consumed, and it will take a long time. In addition, in the breeding process, most of them require experienced professionals to analyze, and the problems in the breeding environment cannot be found in time, and the breeding benefits are low. Therefore, in order to solve such problems, we propose a breeding device for seabass and method
