<p>PCT No. PCT/NL95/00009 Sec. 371 Date Jun. 20, 1996 Sec. 102(e) Date Jun. 20, 1996 PCT Filed Jan. 5, 1995 PCT Pub. No. WO95/18528 PCT Pub. Date Jul. 13, 1995Electro-fishing apparatus comprising a trawling net (16) which during operation is towed over the bottom, a combination of electrodes (10, 12) which, during operation, are towed over the bottom at a distance in front (14) of the net (16), and a pulse generator (28) which is connected to electrodes (10, 12) to generate during operation a pulsed electric field in the water. The electrodes comprise at least partly a number of electrically conducting bodies (10a, 10b, 10c, . . . ) each through a separate connection cable connected to pulse generator (28), whereby the water contacting surface of each electrically conducting body (10) is limited such that a specific electrical resistance is created. The pulse generator (28) is embodied such that each of electrically conducting bodies (10) can be powered separately to generate a field between the momentaneously powered electrically conducting body (10) and another electrode (12).</p> |
