The invention discloses a closed static aquatic organism toxicity experiment device. The closed static aquatic organism toxicity experiment device comprises a transparent experimental container, an oxygen supply container and an excrement collection device. An upper surface of the transparent experimental container is a cover plate which can be opened and closed. The oxygen supply container is arranged in the transparent experimental container. The middle of a lower surface of the transparent experimental container is a funnel-shaped connection piece. A lower end of the funnel-shaped connection piece is connected to the excrement collection device. Compared with the prior art, the closed static aquatic organism toxicity experiment device solves the problems of oxygen supply, realizes real-time acquisition of experimental data of organism excrement, improves experimental accuracy, has a low cost, is convenient for operation, has a small occupy space, is suitable for toxicity experiments of various aquatic organisms in a closed state, and has strong practical applicability and a wide application prospect.
Description
technical field [0001] The invention belongs to the technical field of aquatic biological experiment devices, in particular to a closed static aquatic biological toxicology experimental device. Background technique [0002] At present, in the field of aquatic biological toxicology experimental research in China, self-made devices without uniform specifications and structures are used for experiments in a closed state to meet the needs of their own experiments, and the scalability is poor. Due to limitations in conditions and design, many self-made devices do not carry out the necessary oxygenation because they need to meet the airtight conditions, causing some test organisms to suffocate and die due to lack of oxygen, making it impossible to carry out subsequent experiments. At the same time, due to the airtightness of the device, the real-time experimental data of some biological excrement cannot be collected, which affects the accuracy of the experimental results. Conten...
