Definitions

  • a floating breeding device for fish or the like A floating breeding device for fish or the like
  • the present invention concerns a floating breeding apparatus for fish or the like consisting of at least one net bag suspended from pontoons or the like, the open end of which net bag is attached to at least one ring shaped support enclosing the opening of the net bag.
  • Another problem is the large volume of the net bag when the young fxsh are bred. It would be desirable for the net bag to be relatively shallow in the beginning of the breeding cycle, but still allow free swimming over large distances. Further, it would be desirable that the size of the net mesh be smaller in the beginning of the breeding period, which would also prevent undesired fish from forcing their way into the bag.
  • the purpose of the present invention is to provide a floating breeding apparatus, which can be subdivided in a simple way into smaller, relatively shallow breeding volumes, with the possibility of shutting off such a reduced breeding volume from the surrounding water so that it is essentially water tight.
  • Another purpose of the invention is to be able to change or extend part of or all of the side material of the net bag without requiring that the fish be moved to another container or bag, while retaining the required flexibility for making such reduced breeding volumes.
  • Fig 1 shows a breeding apparatus according to the invention from above.
  • Fig 2 is a section along line II - II in fig 1.
  • Fig 1 shows a part of the side material of the breeding apparatus in a larger scale and in perspective.
  • Fig 4 shows a section along line IV-IV in fig 2.
  • Fig 5 shows a section of a modified exemplification of the side material of the breeding apparatus analogous to the section shown if fig 4.
  • Fig 6 shows a modified exemplification of the breeding apparatus in a side view.
  • the breeding apparatus consists of a net bag 11, the upper opening 12 of which is attached to a ring shaped support 13, which can also be the pontoons of the breeding apparatus.
  • the net bag consists of side material 14, which can be divided into sectors 14a, 14b, 14c etc, connected to each other by flexible or bendable connectors 15 and a bottom 16.
  • a preferably ring shaped body 17 is attached, which in the exemplification shown can act as the sinker of the net bag.
  • the body 17 is appropriately placed concentric with the support 13 and has a smaller diameter and/or circumference than the support, so that the body can be lifted up toward and to a level with the support 13, as is shown in fig 2 by a dot-dashed line, and in which position the side material 14 of the net bag forms a limited volume 18 with significantly reduced size compared with the original size of the net bag.
  • the ring shaped. body 17 can advantageously consist of a tube with variable displacement, where the free inner volume of the tube can be filled with water when it is to be used as a sinker, or alternatively emptied and filled with air when the bottom 16 of the net bag is to be lifted towards the pontoon holder 13. Blowing the tanks of the sinker 17 is appropriately done with a compressor mounted on a service boat.
  • the connectors 15 between the side material sectors 14 are made of flexible or bendable profiled bars 20 and 21, for example made of a rubber material, and have longitudinal tracks 22 in the form of open grooves, in which slides 23 of appropriate form are inserted, for instance fasterners attached to the edges of the side material 14.
  • the connectors 15 are appropriately made with double pairs of tracks 22 and 24 so arranged that an outer side material sector 25 can be placed parallel to and outside the sector shaped side material 14, which outer sector shaped side 25 is equipped with slides in the same way as the sides 14, which slides 26 can be inserted into the open grooves of the tracks 24.
  • the material in the outer side sectors 25 can vary according to the purpose of the outer sides.
  • an outer side sector 25 can be applied in the form of a tarpaulin or the like, so that an essentially water tight outer side is obtained.
  • the connectors 15 In water with strong currents and especially in water where such currents change often, it can be appropriate to make the connectors 15 so that they can act as strain dampers, as is shown in fig 5, and which are also made of a rubber material which can withstand strong pulling forces. It is even possible to make the connectors of a stiff material, for example aluminium, in a number of sections connected to each other by wires pressed to each section, for example, so that the connectors 15 as well as the outer side material sectors 14 and 25 can bend as required when the ring shaped body 17 is lifted toward the water surface.
  • a stiff material for example aluminium
  • ring shaped body 17 Of course it is possible to use more than one ring shaped body 17, for example two of them, at some distance from each other, as is shown in figure 6.
  • One of the ring shaped bodies 17a is placed at the bottom of the net bag as in the previously described exemplification, while the other ring shaped body 17b is arranged for example at half the height of the side.
  • the lowermost body 17a is so much smaller than the intermediate member 17b, as corresponds to the width of the volume 18b which is formed when both bodies 17a and 17b are raised toward the surface of the water.

Abstract

Le dispositif ci-décrit comporte au moins un filet en forme de poche (11) suspendu à des pontons ou similaires, l'extrémité ouverture (12) dudit filet étant fixée à un support annulaire (13) entourant l'ouverture du filet. Le but est de réaliser un appareil d'élevage flottant qui peut être aisément subdivisé en volumes d'élevage plus petits, permettant la séparation d'un tel volume d'élevage réduit de l'eau circonvoisine. On y parvient grâce au fait que le fond (16) du filet en forme de poche (11) peut être soulevé vers l'ouverture de ladite poche et être fixé dans sa position surélevée, formant ainsi au moins un espace (18) limité par le ou les matériaux latéraux (14, 25) de la poche, et présentant un volume réduit comparé au volume initial du filet.
