Excerpt from Directing the Movement of Fish With Electricity The examination of literature available at the time the study was undertaken failed.to yield clear-cut information on the behavior of fish subjected to direct electrical currents or on direct current elec tricel devices that might be employed to lead fish. Therefore, the first part of this investigation was directed toward determining the type of electric current that would be most effective in controlling the move ments of fish. The second phase constituted the investigation of those factors which would affect the efficiency of an electrical leading device as it might be used as an aid in trapping fish to minimize the blocking effect of an alternating current, electrical sea lamprey barrier.
