Automatic biological specimen collecting device

Technical Field

The invention relates to an automatic biological specimen collecting device, and belongs to the technical field of specimen collection.

Background

When the river ecosystem is researched and evaluated, the aquatic organism community in the river is often required to be monitored, and mainly comprises benthos and plankton. Benthonic animals refer to aquatic animals that live at the bottom of a body of water for all or most of their life history. The benthonic animals in freshwater mainly comprise aquatic insects, mollusks, acarids, panonychus, oligochaeta, hirudo, and vortexes. Benthonic animals are widely distributed in water environment, although the benthonic animals are aquatic organisms with relatively weak activity, the benthonic animals play an important role in decomposition of nutrient substances and energy circulation of an aquatic ecosystem, have a strong coupling relation with the surrounding biological environment, and the health of communities is reflected to a great extent by the health degree of the whole aquatic ecosystem. The plankton is a general name of a micro aquatic organism which is suspended in a water body and can only live along with wave flow by flow, and comprises phytoplankton and zooplankton. The plankton has weak active evasion capability and is sensitive to water pollution and water quality change, the type, quantity and distribution of the plankton can change along with the change of water quality, and the water quality pollution condition can be comprehensively reflected.
