Marine ecological disaster prevention and control enclosure experimental device

The utility model provides a marine ecological disaster prevention and control enclosure experiment device which comprises floating grid frame assemblies, a plurality of enclosure pieces are fixed between the floating grid frame assemblies, each enclosure piece comprises a vertical installation frame, a seawater containing bag is arranged in each vertical installation frame, the upper end of each seawater containing bag is open, and the lower end of each seawater containing bag is open. And the upper edge of the seawater containing bag is fixedly connected with the upper end of the vertical mounting frame. The device can ensure that the water body in the enclosure part is not influenced by the external environment, so that experimenters can conveniently identify potential disaster-causing algae in the water body in the enclosure part, research the transformation effect of protozoa on phytoplankton biomass and community structure under the field condition, evaluate the prevention and control effect of protozoa
