Problems solved by technology

This type of research requires the directional collection of a large number of living zooplankton, and the zooplankton collected by the traditional method of collecting zooplankton by adding reagents and fixing them under a microscope cannot meet the needs of this type of research.
At present, there is no uniform and efficient method for the collection of living zooplankton. The zooplankton in the water sample can only be sucked through a straw. The accuracy of the experimental results cannot accurately reflect the real situation of the environment

Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0022] The purpose of this specific embodiment is to provide a zooplankton collection device, which can effectively improve the collection efficiency of zooplankton, and can avoid the problem that the collected zooplankton is doped with too many impurities, which will affect the research.

[0023] Hereinafter, an embodiment will be described with reference to the drawings. In addition, the examples shown below do not limit the content of the invention described...

Abstract

The invention relates to the technical field of water quality monitoring auxiliary equipment and discloses a zooplankton collection device. The zooplankton collection device comprises a water sample container and a collection container. The water sample container is used for holding a water sample and comprises a nontransparent container body with an opening and a nontransparent cover body which covers the opening in an openable and closable manner, the side wall of the container body is provided with an outlet, and a valve for opening and closing the outlet is arranged at the position of theoutlet. The collection container is provided with an inlet which is in detachably airtight butt joint with the outlet, and a light-emitting source is arranged in the collection container. Therefore, the zooplankton collection device is capable of effectively improving zooplankton collection efficiency, and the problem of influences on researching due to excessive impurities in collected zooplanktons can be avoided.

Description

technical field [0001] The application relates to the related technical field of water quality monitoring auxiliary equipment, in particular to a zooplankton collecting device. Background technique [0002] As an important part of the lake ecosystem, zooplankton play a vital role in the process of material transformation, energy flow and information transmission. The species composition, quantity changes, dominant species and pollution indicator species of zooplankton are greatly affected by the natural geographical environment of the lake, the type of water body and human activities. Different species have different sensitivities and adaptability to the environment. Also different. Therefore, zooplankton are often used as an important indicator of water quality monitoring to indicate and evaluate lake ecosystems. [0003] In the field survey at this stage, 25# plankton nets are used to collect zooplankton, which are fixed in formalin and brought back to the laboratory for...
