A suspended cage device for microbial testing

Abstract

The invention relates to the technical field of aquaculture, in particular to a suspended cage device for microbial testing, which comprises a floating box group, a drainage group arranged at the bottom of the floating box group for guiding and discharging foreign matter at the bottom of the box, and the floating box group includes a mesh box and the solid wall box arranged inside, the drainage group includes a vane wheel and a deflector which are located inside the drainage hood and are coaxially connected, and the bottom surface of the deflector is adjusted and connected with a drainage servo motor. The present invention conducts the captive breeding of fish and the test of microorganisms through the set of floating box groups, uses the solid-wall box to isolate the water area, and uses the drainage group to drain the fish excrement that sinks on the bottom surface of the solid-wall box, so as to achieve the effect of filtering water quality, At the same time, the new water quality overflows from the top of the mesh box into the solid-wall box for replenishment, which plays the role of replacing the water quality; thus, in the case of obtaining the microbial decomposition ability, it can also ensure the healthy growth of the fish group, and the floating box can be adjusted in position and flexible. It is of practical value to obtain the situation of microorganisms in different waters for the breeding environment test.

Description

technical field [0001] The invention relates to the technical field of research and development of aquaculture technology, in particular to a suspended cage device for microorganism testing. Background technique [0002] Pathogenic microorganisms such as bacteria, viruses and parasites attack the animal body and cause an immune response. The purpose of pathogenic microorganisms invading animal bodies is to survive, and everything has two sides. In order to make good use of the relationship between microorganisms and aquatic products, establish a complex biological living environment, and increase production for aquaculture, before placing microorganisms, it is necessary to carry out multiple points in different waters. Experiment to ensure that the type and quantity of microorganisms meet the living environment of aquatic animals. Because the multi-point experiment has the characteristics of strong activity, the traditional dam culture does not meet the actual needs. In ad...

AI Technical Summary

Problems solved by technology

Due to the strong activity of multi-point experiments, the traditional dam farming does not meet the actual needs.

In addition, microorganisms have the ability to decompose the excrement of aquatic animals. However, after decomposition, a substance called ammonia nitrogen is produced. White and misty, affecting water quality, not conducive to fish having a good living environment

In addition, fish is a kind of thermotaxis animal. When the temperature difference between day and night is too large, sunlight and warm wind during the day will inevitably make the temperature of the water surface higher than that of the bottom. In order to maintain the symbiotic relationship between fish and microorganisms, If the cage position of captive fish is not adjusted properly, it will not be conducive to the fish to keep warm, and the growth of fish cannot reflect the existence value of microorganisms
