Description
Technical Field
The utility model belongs to the technical field of plankton filtration technique and specifically relates to a convenient to use's a device for filtering plankton is related to.
Background
Most of the existing micro plankton are collected in a trawl net in seawater, and the trawl net needs a rocking car, so that the cost is high; therefore, the collection of ballast water is commonly used, and a layered net mode is adopted, so that the medium-large plankton and the micro plankton are collected separately.
referring to the manufacturing method of the portable ballast water micro plankton collector, the ballast water is used for collecting and distinguishing large planktons and micro planktons.
The mesh of the trawl can be blocked, the trawl is wasted, the particle size of micro plankton is small, the mesh of the net is required to be small, and a large amount of other organisms in the trawl are blocked in the mesh and cannot be filtered. And the abundance of micro plankton in the ocean is low, more seawater needs to be filtered, and the net is blocked, which causes inconvenience.
