Definitions

  • the invention relates to a method for operation of a fishing line in connection with a fishing boat, for handling fish that are removed from the line while the line is being hauled in. Specifically, the invention relates to the handling of fish that are removed from the line while the line is being hauled in, and where the fish are transferred for further processing, such as to a bleeding bin.
  • the invention also relates to a device as defined in the preamble of claim 7.
  • a line consists of a main line to which are fastened a number of snoods at regular intervals along the line. A hook is then fastened to the free end of each snood.
  • the invention has to do with an automatic line hauler mounted on the boat's rail and that is used to haul the line in on board the boat.
  • gaff can also be used. To the extent that a “roller man” is used to catch hold of the fish when the fish falls off or is removed from the hook, this is one of the heaviest and most exposed jobs on board a fishing boat that operates long-lining. The work is monotonous, the roller man is exposed to wind and weather, and there is a high risk of repetitive strain injury in the arms and shoulders. Consequently, this work can be characterised as highly labour-intensive during rough weather at sea. For the fishing industry on shore, the poor quality of fish with gaff damage is a big problem in fillet production, as valuable flesh must be cut away. This represents a financial loss in the form of lost use of the fish raw material.
  • An object of the invention is to provide for a new method and a device for handling the fish that is removed from the hook on the line and to transport the fish automatically on board the boat and into the bleeding bin.
  • the other objects of the invention are: - To achieve a better working environment on board the fishing boat. - To prevent the fish getting flesh wounds by the treatment. - To produce fish of better quality as a result of improved treatment of the catch. - To improve the economy of the crew, since the number of crew on board can be reduced. - To enhance the profitability of firms in the fishing industry as a result of the improved quality of the fish.
  • the characteristic feature of the method according to the invention is that the fish are caused to fall down into a reception container filled with water (seawater) on the outside of the boat and then, assisted by the current of seawater along the boat's side, the fish are carried into a conveyor section downstream of the reception container, from which the fish are conveyed upwards and on board the boat for further processing.
  • water seawater
  • the essential feature of the device as per invention is that it consists of a reception container and a conveyor section that are designed to be arranged on the outside of the boat for collecting the fish that have been dehooked, and to bring them on board the boat, where all or part of the reception container is constructed of a material which allows water to flow through in order to effect the transfer of the fish from the reception container to the conveyor section.
  • the boat When the line is being hauled in, the boat always has a certain propulsion, approximately 2-3 knots, and a stream of water arises running through the reception well, from front to rear, and the water including the dehooked fish is pressed backward and carried through the inlet to and into the conveyor section.
  • the fish is taken up by the conveyor belt and carried up over the rail where it falls down into, for example, a bleeding bin, directly under the outlet from the conveyor.
  • the fish is thereafter processed in the usual manner.
  • the system also uses a different dehooking system than the comparable solutions. According to Norwegian patent application 790472 the fish is dehooked in tube B that lies against the surface of the sea.
  • Figure 1 shows a perspective view of the automatic line hauler mounted on the outer side of the boat's rail.
  • Figure 2 shows an enlarged detail section of the reception well and the conveyor casing from Figure 1.
  • Figure 3 shows a drawing viewed from the side (cross section) of the automatic line hauler.
  • Figure 4 shows the automatic line hauler viewed from above.
  • Figure 1 shows a device for hauling in of a line 12, said device consisting of a reception well 2 and a conveyor casing 5 that are built together to form a single unit.
  • the line hauler is in the form of a primary rail roller with fish dehooker 1 to remove the fish from the hook, a reception well 2 with secondary rail roller 3 where said fish (on the line's 12 snoods) first enter the system and a conveyor casing 5 in which is arranged a conveyor belt. After the fish has been removed from the hook in the primary rail roller, said fish falls down into the reception well 2, directly under said primary rail roller 1.
  • a primary rail roller consists of a number of parallel rollers through which the line is drawn, and said rollers are placed so close to one another that the fish cannot pass through and are thus removed from the line hook.
  • the reception well 2 comprises a container open at the top for reception of fish.
  • the entire reception well 2 is basically made of wall elements of perforated steel plate, or grid, grill or similar elements so that there is a good stream of water into and through said reception well.
  • the front side wall 2a of said well 2 is of the mentioned perforated material permitting the passage of water, while the rest of the well plates 2b are of normal plate material.
  • the perforated openings or vertical slits in the front plate 2b are shown with reference number 30.
  • the bottom surface of the well and the front side surface 2a of the well form from its top a downward-inclining surface.
  • the well's open top 24 is above the water line 26, while the rest of said well is below water. The fish thus fall into the water in the well.
  • the fish can only be carried out of the well with the water current 28, and backward to the rear edge of said well and in through an opening to the conveyor 5.
  • the conveyor also has a lower section that is designed to be under water.
  • the back part of the conveyor bottom is also designed to let water through, i.e. out at the back (or downstream).
  • Inside the conveyor cover 5 is mounted an endless conveyor belt 5 on which said belt are mounted a number of carriers in the form of trays, grids or similar.
  • a drive gear not specifically shown is designed to drive the conveyor belt that is used to carry the fish from the volume of water in the conveyor well and up to the boat's rail 11 for further processing, such as in a bleeding unit.
  • the conveyor cover forms a closed casing whose lower section 5 forms a chamber with wall elements through which water can flow, in the same manner as in the reception well.
  • the conveyor belt can be set in a vertical position or with a suitable oblique position. From the top of the conveyor the fish fall down into a bleeding bin 9 on board the vessel. In the front edge (upstream) of the conveyor cover 5 there is an opening 4 that forms a fluid connection with the opening in the back edge of the reception well.
  • the reception well and the conveyor unit can form a single combined unit, such as indicated in the figures 1.
  • the unit of the reception well and the conveyor unit is designed to be placed affixed to the boat's rail 11 and mounted on the outside of the boat's side in such a way that the other parts of said reception well and conveyor unit respectively are under water when the system is in use.
  • Figure 3 shows in cross section how the line hauler unit as per invention is placed relative to the boat's side 19 and rail 11.
  • Figure 4 shows a similar plane view of the line hauler unit as installed to the rail 11 of the boat.
  • the line hauler unit as per invention is designed as an integral unit which using the boat's winches can be mounted and demounted to the boat's rail. It can also be set out on the outside of the boat's rail using a hydraulic system for mounting and demounting. This again means that the unit can be stored in an appropriate storage space on board and mounted when the lines are to be hauled in.
  • the fish 15 enter with the line 12 through the secondary rail roller 3 (a leader roller) and where the primary rail roller with fish dehooker 1 removes said fish from the hook on said line 12, and said fish fall into the water in the reception well 2.
  • the fish are then carried into the conveyor 5 through the inlet 4 in the conveyor 5 because of the stream of water through the reception well and as a result of the incline in the bottom of said well 2.
  • the conveyor 5 with carriers 7, and which is driven by a hydraulic motor 6, carries the fish upward in said conveyor 5 and out through the outlet 8 in the top of said conveyor 5. After the fish are carried out of the outlet 8 in the conveyor 5, they fall straight down into the bleeding bin 9 on board the boat.
  • the conveyor is operated by the "roller man" via a control valve 10.

Abstract

La présente invention concerne un procédé de mise en oeuvre d'une palangre en relation avec un navire de pêche et un procédé de manipulation des poissons décrochés de la palangre pendant qu'on la rentre. La caractéristique essentielle du procédé est qu'on amène les poissons à tomber dans un bac de réception (2) rempli d'eau (eau de mer) à l'extérieur du navire. A cet endroit, le courant d'eau de mer le long de la coque transporte les poissons jusqu'à un convoyeur (5) en aval du bac de réception d'où ils sont remontés sur le pont pour la suite du traitement. L'invention concerne également un dispositif mettant en oeuvre le procédé de l'invention.
