摘要： PURPOSE:To suppress the invasion of animate nature into the inside of an invasion interrupting part by electric stimulation by allowing a conductive liquid to flow between 1st and 2nd electrodes by a flowing means and impressing voltage from a power supply to the 1st and 2nd electrodes. CONSTITUTION:The conductive liquid is allowed to flow between 1st and 2nd electrodes 3, 4 by the flowing means 11, voltage is impressed from the power supply to the 1st and 2nd electrodes 3, 4 and a current path is formed between the electrodes 3, 4 by the flowing conductive liquid. Thereby, the electric field with the prescribed intensity is formed in the current path, i.e. the liquid part and the invasion of animate nature into the invasion interrupting part is suppressed by the electric stimulation of the electric field. Since no obstacle exists between the electrodes 3, 4 when current supply to the conductive liquid is stopped, organisms can easily pass the invasion interrupting part without generating any trouble.

摘要： PURPOSE:To reduce its power consumption, by placing a plurality of electrodes at regular intervals and parallel to each other, and setting the ratio of the distance between adjacent electrodes to the length of each of the electrodes to a value that satisfies a specific relation. CONSTITUTION:A plurality of flat-plate-shaped electrodes 1 are placed at regular intervals and parallel to each other at its swimming-interrupting portion beneath the sea, and one of the output terminals of its electric source 2 is connected across every other electrode 1 while the other output terminal connected across the rest of electrodes 1 so as to provide the electrodes 1 with respective potentials in such a manner that adjacent electrodes 1 have different potentials. Then each of the distances D between the electrodes 1 and the length L of each of the electrodes are set to respective values so that the ratio of D to L satisfies 1

摘要： PURPOSE:To reduce electrical influences on adjacent facilities, buildings and, etc., by forming an electric screen intercepting what fishes and shellfishes go in and out so as to be arranged in the direction that plural electrode units are cut at a right angle to the intercepting direction for placing the same in the direction that an electrode row with grounding potential is cut at a right angle in cross proximity to each electrode unit. CONSTITUTION:Plural wide electrode units 3 are arranged in the direction almost transverse to an intercepting direction that access of fishes and shellfishes is intercepted, and also are placed in the direction that an electrode row 4 with grounding potential comprising plural electrode bars arranged in cross proximity to each electrode unit 3 is cut at a right angle. And one of two adjacent electrode units 3 is connected to a positive power terminal of a d.c. power supply 5, while the another electrode unit 3 and the electrode row 4 are connected to a negative power terminal of the power supply 5 for grounding. Thus, outside the area that fishes and shellfishes are prevented from entering, the intensity of an electric field gets high in no steps with approach to an entry preventing area, while inside the entry preventing area, the intensity of the electric field abruptly gets low into zero due to the electrode row 4 with the grounding potential. That results in avoiding electrical influences in the preventing area.

摘要： PURPOSE:To achieve the recovery of a paralyzed fish and prevent a damage such as apparent death thereof by detecting the fish entering between electrode lines, which is paralyzed by an electric screen between the both electrodes and sink to the bottom of the sea, and extending the space between the both electrode lower parts. CONSTITUTION:When fishes enter between electrode lines 1, 3 in a state where an electric screen of a determined electric field strength is formed between said electrode lines by an electric source 12, they are detected by detecting means 13, 14, which means then output to comparators 16, 17. A timer circuit 18 is operated by the build up to a higher level of the output of the first detecting means 13 to output a signal of T time H. Then the fishes entering between the electrode lines fall into a state of paralysis, often loosing swimming ability to sink to the bottom of the sea. These are detected by the second detecting means 14, and the H output is sent from the comparator 17. An AND gate 21 outputs a drive command signal of H by the H output of the timer circuit 18 and an inverter 20 and the H output of the comparator 17 to operate a moving motor 9, which extends the lower part space between the electrode lines to weaken the electric field strength, so that the recovery of the sunk fish is achieved.
