Abstract

The invention discloses a concentrating device and a concentrating method for plankton in a water body, wherein the concentrating device includes a fixed frame and a concentrating container with a closed inner cavity fixedly installed on the fixed frame, and the concentrating container has a The water injection port on its upper part, the drain port at its bottom, and the water discharge port on its side. The water discharge port is fixedly connected with an upwardly curved elbow, and a water valve is arranged on the elbow. A filter screen for collecting plankton in the water body and a support net supported under the filter screen can also be detachably provided. There is also a vent valve below the bottom, and the valve port of the vent valve is located above the filter screen. The device is simple and easy to operate, and the concentration method carried out by using the concentration device is simple and easy, and can be used for concentrated sampling of water body plankton from a large number of water samples, and has high efficiency.

Description

technical field [0001] The invention relates to a concentrating device and a concentrating method for plankton in a water body. Background technique [0002] In aquatic biology research, it is often necessary to collect a certain volume of water samples and fix and concentrate them to prepare a certain volume of concentrated samples for qualitative and quantitative analysis of plankton. In the traditional concentration method, a precipitator is mainly used, and the sample can be prepared only after repeated precipitation and constant volume. The precipitation time is long and the process is cumbersome. Therefore, there is an urgent need for a simple and fast concentration device and concentration method for plankton concentration in water bodies. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art, and provide a plankton concentration device with simple structure and convenient operation, which is used ...
