Description

Device for collecting water body plankton in high-altitude area

Technical Field

The utility model relates to a biological collection technical field specifically relates to a device for gathering high altitude area water body plankton.

Background

Plankton (plankton) is a group of organisms in water areas such as oceans, lakes, and rivers, which have no ability to move by themselves or are very weak and thus cannot move against water flow and float on the water surface, and is generally called plankton. This is an ecological group defined according to the type of lifestyle. Rather than the division concept of biological species.

Plankton can be divided into six categories according to individual size: giant plankton larger than 1 cm, such as jellyfish; large plankton of 5-10 mm, such as large copepods and shrimps; middle plankton of 1-5 mm, such as small jellyfish and copepods; small plankton, 50 micron to 1 mm, such as diatom, blue algae; micro plankton of 5-50 μm, such as dinoflagellate and chrysophyceae; ultramicro plankton, less than 5 μm, such as bacteria.

Traditional collection system can only single collection, can not effectual multiple sample of collection, and the latency of gathering the sample moreover needs to keep the activity of water to guarantee the normal living environment of sample.
