Description

Technical Field

[0001] The utility model relates to the technical field of fish breeding, in particular to a fish exposure culture device. Background Art

[0002] In the process of fish breeding, it is necessary to ensure that the water quality is clean and pollution-free to prevent the fish from eating harmful substances in the water and becoming diseased. Therefore, the water for fish breeding needs to be replaced in time. At the same time, the water for fish breeding needs to have a high dissolved oxygen content to prevent the fish from dying due to lack of oxygen. At present, more and more laboratories around the world are using fish as research objects, and they have wide applications in life sciences, environmental sciences, etc.

[0003] However, fish breeding has the disadvantages of heavy labor, low work efficiency, and time-consuming and costly. In the current laboratory breeding environment, they are usually kept in buckets. Changing water and feeding every day seriously wastes the precious time of experimenters. It is not only time-consuming and labor-intensive, but also may cause unnecessary interference and fluctuations to the fish, increasing experimental errors; and buckets usually do not have special oxygenation equipment and cannot provide sufficient oxygen for fish. In addition, for experiments that need to simulate specific environmental pollutants (such as perfluorinated compounds), traditional fish breeding devices lack a special pollutant liquid supply system, so experimenters cannot accurately control the concentration and amount of pollutants added, and thus cannot effectively simulate the environmental conditions required for the experiment.

[0004] To this end, a fish exposure culture device is proposed. Utility Model Content
