[Injury to fish by turbine plants].
In the Federal Republic of Germany, 7% of the electric power is generated by Hydro-electric plants. A water current is used to drive a turbine, to generate electricity. Fish are passively drawn into the turbines by the water flow, or they migrate actively downstream (eels). Fish then may be injured or even killed. The national Countries' Fishery Acts are not sufficient to compel the prevention of fish gaining access to the turbines. To compensate for losses to the fishery, the owners of Hydro power plants can re-stock their water supplies. Superior to the Fishery Acts of the various Countries is the Federal Animal Protection Law. According to its principle, it is not allowed to cause pain, suffering or damage to an animal without a reasonable cause. It cannot be the intention of either the Fishery Acts or the Animal Protection Law to compensate losses in the fish population by re-stocking. On the contrary, the damage has to be prevented in advance. A suitable means to achieve this is the combination of electrified barriers with a bypass for fish.
