Definitions

  • This invention relates to a fishing system for use with a moving boat located on a surface of a body of water.
  • this invention relates to a rotatable fishing system that can be used on a commercial basis with a small boat to catch fish, more particularly, -ground fish.
  • Ground fish for example, cod, haddock and halibut
  • cod cod
  • halibut ground fish
  • this method requires a lot of energy, problems can be encountered where the bottom is uneven or rocky the net can cause environmental damage ,to the bottom and poor results are achieved where there are low concentrations of fish.
  • the fishing lines have baited hooks on a free end.
  • the long line is strung out and anchored on.the ocean floor with floats at the either end. After an appropriate time interval, the line is pulled into a boat and any fish caught on the hooks are removed.
  • This method requires a large energy input but it only covers a relatively long and narrow area of the continental shelf when it is used. Also, since the line is lying on the floor, the bait hooks are difficult to detect. On a smaller scale, it is known to catch ground fish by a method called hand lining.
  • the hand line is smaller and shorter than the long line described above. The hand line is hung over the side of a small boat and suspended above the floor with numerous fishing lines extending therefrom at spaced intervals.
  • the fishing lines have baited hooks on a free end.
  • two hand gU STlTUTSSHEE lines are used simultaneously with one line being hung from each side of the boat.
  • These hand lines cover only a small area and sometimes the two lines become tangled with one another.
  • a great deal of fishing time is lost when the net or the lines are being placed in the ocean or are being retrieved from the ocean.
  • the lines being used must be periodically rebaited or replaced with previously baited lines. It is very time consuming and expensive to rebait the lines. If replacement lines are used, the cost of equipment also increases.
  • a rotatable fishing system can be used with a moving boat located on a surface of a body of water.

  • Figs. 2 and 6 there are means to catch fish affixed to a free end of the fishing lines 10. These means are usually hooks or lures 86. If hooks are used, they would normally be baited. In some uses, it might be desirable to alternate hooks and lures on adjacent fishing lines of a cable or to use some other combination of hooks and lures on said cable 8. However, as bait is expensive, it is preferred to use lures on all of the fishing lines 10. Lures are designed to simulate swimming bait when the lures are pulled through the water. Since the cable 8 rotates in one direction, the fishing system of the present invention is particularly suited for using lures.

  • the tether is designed so that it can be lengthened or shortened easily. This could be done in many different ways. One way, which is not shown in the drawings, would be to attach one end of the tether to a wind-up pulley located on the boat.
  • the continuous cable 8 also has a point or points 108 where it can be opened or broken so that additional lengths of cable can be inserted to make the loop larger. Alternatively, the continuous cable can be shortened by removing a given length of cable at points 108.
  • the size of the continuous loop and the length of the tether can be readily determined.
  • the frame After the frame has been placed in the water, it will sink by gravity towards the floor. As the frame is sinking, the cable 8 will likely not be in contact with the rollers 58.in the two discs 42. However, once the frame reaches the pre-determined level beneath the surface, the cable 8 will slide along one of the radial 5 members 54 until such time as it becomes centred on the roller 58. If hooks are used on the fishing lines 10 of the cable 8, these would likely be baited before the cable is placed in the water.
  • the system - could be placed in the desired position beneath the 0 surface and then the cable 8 ' could be rotated and the fishing lines baited in the boat as they pass through the boat. Even if the lines 10 are pre-baited, as the bait is consumed through the use of the system, the hooks will have to be re-baited as they pass through the boat before 5 re-entering the water. If lures are used, then baiting and re-baiting are unnecessary. Since the fishing system is designed so that a large portion of the cable 8 is suspended at the same depth above the floor- 24, the baited hooks or lures 6 can readily be seen by fish.

  • the boat is then driven slowly through the water pulling the frame 12 behind it, while watching the depth finder to ensure that the depth remains reasonably constant. If obstacles are encountered on the floor, the frame 12 can be raised relatively quickly by increasing the boat speed. While any reasonable boat .speed can be used, a speed ranging from one to one and one-half knots is suggested.
  • the length of cable between the two discs 42 can be exposed to fish, the movement of the cable 8, the fishing lines 10 and the baited hook or lures 86 will likely cause the fish to be attracted to the fishing lines 10.

  • the speed of rotation of the cable 8 will vary with the conditions desired by the operator of the boat.
  • One suggested speed of rotation of the cable 8 is approximately three feet per second. However, any reasonable speed of rotation could be used.
  • the angle of the fishing lines 10 relative to the cable 8 in the area between the two discs 42 will vary with the speed of rotation of the cable 8 as well as the forward speed of the boat 2 could be moved in various ways, including allowing the boat 2 to drift on the water.

Any appropriate angle can be used but an angle of 10 degrees relative to the cable 8 extending between the two discs is suggested.
  • the purpose of angling the discs 42 as- shown in Figure 8 is to cause downward pressure to be exerted on said discs 42 and the frame 12 as they are pulled through the water by the boat.
  • the actual angle could be more or less than 10 degrees, as desired. Exerting downward pressure on the frame- and discs can be accomplished in various alternative ways.

  • the purpose of causing downward pressure to be exerted on the discs 42 and frame 12 is to prevent the system from rising too much towards the surface as the speed of the boat increases. Where downward pressure is exerted on the frame and discs, it would be possible, with the same length of cable 8 and tether 14, to operate the boat at a higher speed, while maintaining the frame and discs at or near the same depth.
  • the fishing system of the present invention is designed so that most of the fish will be caught by the fishing lines that are moving between the two discs. However, if a fish is caught on a fishing line either before the first disc or after the second disc, there is nothing in the system that will cause the fish to be removed from the fishing line before it reaches the boat.

  • many of the fishing lines 10 have been omitted from the drawings. For example, in Fig.1, the fishing lines 10 are actually spaced equally along the full length of the cable 8 but are only drawn in in a few small groups of lines 10.
  • the fishing system of the present invention is particularly suited to the se of lures rather than hooks or baited hooks as the movement of the cable 8 pulling the fishing lines continuously through the water causes the lures to move in a manner that can be attractive to fish.
  • the advantage of using lures instead of hooks is that the lures to not have to be baited. This not only saves time, it is also much more convenient and less expensive.

Abstract

Un système de pêche peut être utilisé avec un bateau (2) en déplacement à la surface d'un plan d'eau. Le système comprend un câble sans fin (8) duquel pendent à des intervalles des lignes de pêche (10). Un dispositif de guidage du câble (8) est placé sur le bateau (2), de même que sur un cadre (12) suspendu sous la surface de l'eau à une attache (14) connectée au bateau (2). Le cadre (12) a deux extrémités portant chacune un disque (42) comportant un rouleau (58) qui sert de dispositif de guidage pour le câble (8). Le câble (8) s'étend sur tout le dispositif de guidage formant une boucle fermée. Un dispositif (80, 84) sur le bateau (2) met le câble (8) en rotation sur le dispositif de guidage. A mesure que le câble (8) tourne, le bateau se déplace ou dérive de sorte que le cadre (12) puisse être tiré à travers une zone relativement étendue en relativement peu de temps. Lorsque les poissons sont pris aux lignes de pêche (10), ils sont ramenés sur le bateau (2) et enlevés des lignes de pêche (10) avant que celles-ci ne soient retournées sous l'eau par le câble en rotation. Ce système de pêche convient particulièrement pour attraper des poissons de fond.
