FISHING BY ELECTRICITY
i Experiments in fishing with electricity were conducted in Germany and -Sweden with considerable success before the war, and now other fishery authorities, including our own, are conducting further research and tests with the method. The nets consist of electrical current, passing between electrodes adjusted to the boats by special projecting rigs. The fish are stunned Hy the shock when the} swim into the path of the current, rise to the surface and are gathered in. An advantage of the idea is that, since the fish arc not killed but merely numbed, they can be kept alive after they are caught or put back in the water if nut wanted. In the experiments, it was found that large fish were killed by strong current, I although smaller ones slipped by un- [ harmed. The current, therefore, can be regulated to trap fish of a desired size.
