Fish! ang device

Most of the fishing is done with trawls in

Netzsteert often injures fish and is known outside of the box. The arrangement for producing the reduction in the quality of the meat by dehydration as such is not the subject of the present definition of products of fatigue in muscle meat
on.

Except the trawls are for fishing Sinknets known, with which, in contrast to the 30 trawl over rocky and uneven ground and can be fished in the intermediate water, but this is not prevalent, at least in deep-sea fishing to have. The reasons for this are obvious

in that the probability is relatively low, iron can be made, and advantageously seawater that the fish is equipped by itself in the interior of the sink, there is a net bell 2, swimming net and while closing the which together with the frame 1 to the holding net or when hoisting the rope 3 in the net is attached. Instead of the tethers you can also lent fish through the moving network parts to escape - a pipe or frame construction used movements are caused, and thus become part of 40. The mesh bell can have any shape the openings of the net that are still present are seated, for example also semicircular, escape. On its underside, the frame 1 carries the folding

The invention relates to a new type of fishing gear, pen 4, 4 α, which is movable in hinges 5, 5 a and avoids the disadvantages described above. That depends are. The flaps 4, 4 a are not advantageous. The device is suitable for both freshwater and, 45 directly on the frame Ϊ, but rather on something, and preferably for deep-sea fishing. With the aid of the cross member 6 arranged below the frame, in particular deep-standing
Fish are captured.

The essence of the new device is - that kind of a frame that can be lowered into the water at 50 the top is a mesh bell and on the bottom flaps, which close the mesh area be able to close. Underneath or inside the device, elevating and lowering elec-

Since the radiation by nature of the water resistance, the flaps are advantageous - ^: "The more fish are received with perforations, the more fish are provided with perforations, which do not allow any fish to pass through between the radioactive substance and the Empaber. The cable pull-" for Catchers are present, can be seen by observing the movement of the flaps is advantageous via deflection - 5 of the rollers 9, 9 a at the edge of the frame 1 and others arranged in the various height levels. Recipients estimate the degree of filling of the device relative to pulleys 10, 10a in the middle of the frame too easily. The device can be guided in such a way that the closing cable 11 is positioned next to the carrier that the receiver (s) leads upwards with a cable 12 to which the holding cables 3 for the entire device-independent device for switching off the power supply are attached . "io impulses and to close the flaps 4, 4 a gekup-Instead of the flaps 4, 4 a with the help of the Iiubseile 8, pelt are such that when removing or stopping to move 8 a, a construction is also conceivable, the radiation the Impulses stop and the flaps which the flaps close automatically with the help of electric motors.Instead of the arrangement of radios, which are arranged directly on the device, with or active substances, ultrasonic transducers can also be moved up and down without appropriate pulling cables. 15 in the same way at different heights on An electrode device can be mounted under the frame 1 to catch tightly, with the opposite 13 on a cable feed 14, which is provided with corresponding resonators on the side of the device for emitting impulse currents into the water, which absorb the ultrasonic vibrations 13 can be raised and lowered. be arranged so that they can be operated with the accumulating 20 The new fishing gear is pulled up into the interior of the net bell with particular advantage from a corresponding fishing vessel. Instead of a liftable and lowerable electrode, a plurality of electrodes can be arranged at different heights, for example by means of two electrodes provided in the ship. The lockable shaft that is let into the water. The drawing reveals another frame size of about 4X4 or electrode 15, which can be encased 6 X 6 m edge length at a height of the net, while at the same time the deeper bell of about 5 m than proved suitable. The final electrode 13 is turned off. Catching yourself with the help of the device happens as follows: Since the forwarding of the catching impulses is proportionate - After you have determined the location of a moderately very strong cable by echo sounding, recommends 30 appropriate fish school, it will be the impulse generation system, which is in the device with the flaps open to just above the Fisch rule from the rectifier, the pulse capacitor, school lowered, the exact distance at the Ignitron to the pulse discharge and possibly the most advantageous through the transformers present on the device, determined as close as possible to the echo near sounder will. Now the electric fishing gear is to be arranged in order to be switched on in this way to the line impulse system, which immediately saves electricity. The impulse device is in the taxis where the fish enters. Shown with 1 to 2 seconds from drawing at 16, with a water and stand, the movable electrode must then be used in the indruck tight container when the net bell is pulled up, or it is not preferred to use the container with insulating oil or the like. To fill the pulse output from the outer electrode 13 on the. The arrangement of the pulse generation system 40 internal electrode 15 is switched. The pulling up of the at this point has the advantage that a simple three-phase cable 17, usually of the net bell, takes only a few seconds to feed the fish attracted by the fishing gear into the interior current. Can be used with out of construction. In the drawing, the filling level of the device, which is determined by the above the electrode with the pulse generating system of the filling level meter described, is arranged laterally offset for clarity; 45, the flaps 4, 4a are closed, but it is expedient to switch them off on the main suspension cable 12, and the entire device is fastened in the middle of the device. is lifted out of the water with the help of a winch for precise control of the device. Appropriately, before pulling up the preferred embodiment of the invention on the device, the fish located therein will continue to be anesthetized or killed by a frame 1 rangefinder for small pulse trains of a suitable size. Ground clearances, so-called near-echo sounders, in order to obtain them in optimal quality,
known circuits attached, as indicated at 18, 18 a. A particular advantage of the device is still indicated. These near-echo sounders serve to ensure that tearing of the net bell is practically impossible even with a precise determination of the distance of the underside of a very rich catch, because the fishing gear from the upper end of the school of fish 55 essentially reduces the weight of the fish sta- or the so-called fish school. The anbile and inclined flaps can be worn,
should be made so that the near-echo sounder a automatic activation of the electrical impulses

For this purpose, top bell (2) and on the underside advantageously half of the frame 1, for example on the support-perforated flaps (4, 4a), can be arranged at different heights which ropes 3 ^ radioactive substances, the simplest ⁶ 5, can close the network from below,
