A device for measuring the action potential of aquatic organisms, using two electrodes enclosing between them the whole space in which the aquatic organism, preferably a fish, is free to move. The first electrode floats on the water surface and the second is, e.g. on the floor of the measuring aquarium. The device can be built so large that the stress due to cramped conditions, usually influencing the fish, does not have any effect on the measurement. A device according to the invention can also be located directly in a natural water system. Further, a method is disclosed for monitoring the quality of water and investigating aquatic organisms using a device assembly according to the invention. |
