[0002] Fishery refers to the social industry sector in which humans utilize the material transformation function of organisms in water bodies to obtain aquatic products through fishing, breeding and processing. Fishery is an important part of agriculture in a broad sense. Fishery mainly relies on water resources for breeding. Plankton often lives in water resources. Zooplankton is a general term for heterotrophic invertebrates and chordate larvae that often float in the water and cannot produce organic matter by themselves. Some zooplankton will have a certain impact on fishery breeding. Therefore, it is necessary to collect and test the zooplankton in the water before conducting fishery breeding.

[0003] As disclosed in publication number CN220823853U, a zooplankton collection device includes a collection body, the upper end of which is connected to a floating mechanism, the collection body includes a net, the net is composed of a columnar collection part and a conical filter part, the mesh inner diameter of the collection part is larger than the mesh inner diameter of the filter part, so that zooplankton can pass through the collection part but cannot enter and exit the net from the filter part, and a shielding cover is slidably provided on the periphery of the collection part, which is in contact with the collection part and covers its mesh. The zooplankton collection device expands the area of ​​the collection device that zooplankton can enter by providing a collection part that can enter zooplankton, thereby improving the efficiency of collecting zooplankton. At the same time, by providing a movable shielding cover, the collection area is guaranteed during collection, and zooplankton is prevented from falling out during salvage, thereby ensuring the normal use of the device.
