Description

PROCEDE POUR LA PECHE AU THON, DISPOSITIF POUR SA MISE EN OEUVRE, ET ASSEMBLAGE DE TELS DISPOSITIFS. PROCESS FOR FISHING WITH TUNA, DEVICE FOR IMPLEMENTING SAME, AND ASSEMBLY OF SUCH DEVICES.
La présente invention concerne un procédé pour la pêche au thon et aux poissons similaires.The present invention relates to a method for fishing for tuna and similar fish.
L'invention concerne également un dispositif pour la mise en oeuvre de ce procédé, et un assemblage de tels dispositifs.The invention also relates to a device for implementing this method, and an assembly of such devices.
Par "poissons similaires", il faut ici entendre des poissons présentant des moeurs analogues à celles du thon, plus précisément des poissons ayant tendance à se rassembler sous des corps flottants tels que des pontons ou des épaves flottantes.By "similar fish" is meant here fish presenting mores analogous to those of tuna, more precisely fish tending to gather under floating bodies such as pontoons or floating wrecks.
Un procédé connu de pêche au thon consiste à capturer le poisson au moyen d'un filet déployë verticalement suivant une disposition approximativement cylindrique. Le filet est ensuite resserré et le poisson y est récupéré au moyen d'épuisettes. La difficulté dans ce genre de pêche consiste à repérer une zone particulièrement poissonneuse oùjeter le filetCette détection s'effectue soit par visée à partir d'aéronefs, soit par mesure de la température de l'eau, pour repérer les zones où, en raison de ses moeurs, le poisson a le plus de chance de se trouver.A known method of tuna fishing consists in catching the fish by means of a net deployed vertically in an approximately cylindrical arrangement. The net is then tightened and the fish is recovered there by means of landing nets. The difficulty in this type of fishing consists in locating a particularly fishy area where to cast the net. This detection is carried out either by aiming from aircraft, or by measuring the water temperature, to locate areas where, due to its manners, fish are more likely to be located.
Ce procédé est relativement long et coûteux, et il n'influe en rien sur la concentration des poissons; qui peut être médiocre. La présente invention vise à réaliser un procédé qui donne une efficacité accrue à la capture au filet en permettant d'opérer sur des zones à forte concentration de poisson.This process is relatively long and expensive, and does not affect the concentration of the fish; which can be mediocre. The present invention aims to carry out a method which gives increased efficiency in catching by net by making it possible to operate on areas with a high concentration of fish.
L'invention vise également un dispositif permettant d'appliquer ce procédé.The invention also relates to a device for applying this method.
Suivant un premier aspect de l'invention, le procédé pour la pêche au thon et aux poissons similaires consiste à entourer une certaine zone de la mer au moyen d'un filet que l'on referme ensuite. Il est caractérisé en ce que, avant de placer le filet, on place dans ladite zone un radeau présentant une certaine opacité, et en ce qu'on met le filet en place après avoir observé un rassemblement suffisant de poissons sous le radeau. Aucune recherche de zone poissonneuse n'est alors nécessaire puisque la concentration du poisson est opérée artificiellement par la présence du radeau dans la zone choisie.According to a first aspect of the invention, the method for fishing for tuna and similar fish consists in surrounding a certain area of the sea by means of a net which is then closed. It is characterized in that, before placing the net, a raft having a certain opacity is placed in said zone, and in that the net is placed after having observed a sufficient gathering of fish under the raft. No search for a fishing area is then necessary since the concentration of the fish is operated artificially by the presence of the raft in the chosen area.
Suivant un second aspect de l'invention, le dispositif pour la pêche aux thons et aux poissons similaires est caractérisé en ce qu'il comprend un anneau flottant souple dont l'intérieur est occupé par une surface relativement opaque.According to a second aspect of the invention, the device for fishing for tuna and similar fish is characterized in that it comprises a flexible floating ring whose interior is occupied by a relatively opaque surface.
Grâce à sa constitution sous forme d'anneau souple, le radeau peut être facilement replié et stocké à bord entre les opérations de pêche proprement dites.Thanks to its constitution in the form of a flexible ring, the raft can be easily folded up and stored on board between the actual fishing operations.
Suivant une réalisation préférée de l'invention, le dispositif comprend un filet périphérique fixé sur le pourtour du radeau, et des moyens d'accrochage pour maintenir le filet replié au niveau du radeau, ces moyens d'accrochage étant déverr ouillables pour permettre au filet de se déployer et de s'étendre sous le radeau. Grâce à' cette disposition, on évite l'emploi d'un navire auxiliaire pour déployer le filet autour du radeau.According to a preferred embodiment of the invention, the device comprises a peripheral net fixed on the periphery of the raft, and attachment means for keeping the net folded at the level of the raft, these attachment means being unlocked to allow the net to deploy and extend under the raft. Thanks to this arrangement, the use of an auxiliary vessel to deploy the net around the raft is avoided.
Suivant une première variante de réalisation, le dispositif comprend un certain nombre d'arceaux de guidage fixés sous le radeau pour guider le filet dans son déplacement, pour former cloche sous le radeau.According to a first embodiment, the device comprises a number of guide hoops fixed under the raft to guide the net in its movement, to form a bell under the raft.
Suivant une seconde variante de réalisation, un cordon de serrage est enfilé le long du bord inférieur du filet.According to a second alternative embodiment, a drawstring is threaded along the lower edge of the net.
D'autres particularités et avantages de l'invention ressortiront encore de la description détaillée qui va suivre.Other features and advantages of the invention will emerge from the detailed description which follows.

En référence aux figures I et 2, un radeau 1, représenté flottant a. la surface de la mer, comprend un anneau souple 2 réalisé sous la forme d'un boudin gonflable. Dans la partie centrale du radeau est tendu un filet 3 et, sous ce filet est placée une feuille de caoutchouc 4.Referring to Figures I and 2, a raft 1, shown floating a. the surface of the sea, comprises a flexible ring 2 produced in the form of an inflatable tube. In the central part of the raft is stretched a net 3 and, under this net is placed a sheet of rubber 4.
Cette feuille présente une certaine opacité, vue du sein de l'eau, relativement à la surface de la mer autour de l'anneau, et elle présente une certaine concavité vers le haut, de manière à donner au poisson l'illusion d'une coque de navire.This leaf has a certain opacity, seen from the breast of water, relative to the surface of the sea around the ring, and it has a certain concavity upwards, so as to give the fish the illusion of a ship hull.
Des appeaux 5 sont fixés sur le filet 3. Les appeaux sont sonores, lumineux et olfactifs. Les premiers sont alimentés en énergie électri que à partir d'une bouée houlomotrice (non représentée).Calls 5 are fixed on the net 3. The calls are sound, light and olfactory. The former are supplied with electrical energy only from a wave buoy (not shown).
Une caméra de télévision orientable 6 est suspendue au filet 3 et disposée pour observer la zone située sous le radeau. Elle est reliée par voie hertzienne, par l'intermédiaire d'une antenne 7, à un récepteur situé dans le navire d'accompagnement 8. Elle est alimentée en énergie électrique de la même manière que les appeaux. Pour appliquer le procédé de pêche conforme à l'invention, le navire 8 mouille le radeau 1 sous lequel les thons tendent à se rassembler. On observe ce rassemblement grâce à la caméra 6, puis, quand il est jugé suffisant, un navire auxiliaire 9 déploie autour du radeau un filet 11, tel qu'une senne, s'étendant verticalement dans l'eau. Ensuite, le navire auxiliaire tire sur un câble enfilé sur le bord inférieur de ce filet pour restreindre la superficie encerclée et fermer la partie inférieure du filet.An adjustable television camera 6 is suspended from the net 3 and arranged to observe the area located under the raft. It is connected by radio, via an antenna 7, to a receiver located in the accompanying ship 8. It is supplied with electrical energy in the same way as the calls. To apply the fishing method according to the invention, the vessel 8 anchors the raft 1 under which the tuna tend to gather. This gathering is observed using the camera 6, then, when it is deemed sufficient, an auxiliary ship 9 deploys around the raft a net 11, such as a seine, extending vertically in the water. Then, the auxiliary vessel pulls on a cable threaded on the lower edge of this net to restrict the area encircled and close the lower part of the net.
Quant l'aire encerclée est suffisamment réduite, on dégonfle l'anneau 2 et l'on hisse à bord le radeau que l'on peut aisément replier, puis on capture à l'épuisette le poisson enfermé. On va maintenant décrire, en référence aux figures 3 à 6, une autre forme de réalisation de l'invention. Sur ces figures, on a utilisé les mêmes numéros de référence, augmentés de 100, que sur les figures 1 et 2 pour désigner des éléments similaires.When the area encircled is sufficiently reduced, the ring 2 is deflated and the raft is hoisted on board which can easily be folded, then the trapped fish is caught with a landing net. We will now describe, with reference to Figures 3 to 6, another embodiment of the invention. In these figures, the same reference numbers have been used, increased by 100, as in Figures 1 and 2 to designate similar elements.
Un radeau 101 est formé d'un anneau souple gonflable 102 entourant un filet 103 garni d'appeaux 105 et une feuille de caoutchouc 104. Au centre du filet est fixée une caméra orientable 106 communiquant, via une antenne 107, avec un récepteur situé sur un navire d'accompagnement.A raft 101 is formed by an inflatable flexible ring 102 surrounding a net 103 furnished with calls 105 and a rubber sheet 104. In the center of the net is fixed an adjustable camera 106 communicating, via an antenna 107, with a receiver located on an accompanying ship.
Un filet cylindriq.ue 111 a son bord supérieur fixé à l'anneau 102 par ces crochets détachables fonctionnant par électro-aimants, de manière à permettre la désol idarisation du filet et de l'anneau. Le filet porte, sur son bord supérieur, un certain nombre de flotteurs 112 lui permettant de flotter lorsqu'il est détaché de l'anneau.A cylindrical thread 111 has its upper edge fixed to the ring 102 by these detachable hooks operating by electromagnets, so as to allow desol idarisation of the thread and the ring. The net carries, on its upper edge, a number of floats 112 allowing it to float when it is detached from the ring.
Des arceaux 113 constitués par descables d'acier sont fixés sous l'anneau 2 par leur extrémité de manière à constituer une cage en cloche sous l'anneau. Un lest 114 est filé au point de croisement de ces arceaux.Poles 113 formed by steel downspouts are fixed under the ring 2 by their ends so as to constitute a bell cage under the ring. A ballast 114 is spun at the crossing point of these arches.
Le filet 111 porte des anneaux en¬filés sur ces arceaux de manière à pouvoir venir envelopper complètement la cloche formée par les arceaux en emprisonnant le poisson (figure 4) .The net 111 carries rings threaded onto these arches so as to be able to completely envelop the bell formed by the arches by trapping the fish (FIG. 4).
Pour éviter le fronçage au voisinage du point de croisement des anneaux, le bord in¬férieur du filet est enfilé sur des tringles 115. Chaque tringle a ses extrémités coulissant sur deux arceaux voisins et elle est en deux parties réunies par une articulation 116. Ainsi, quand le filet est déployé (figures 4 et 6), ces tringles obligent le filetà former des plis 117 (figure 4) qui évitent le fronçage. Des lests 118 accrochés aux points d'articulation 116 assurent que les plis se forment vers l'extérieur de la cage. En outre, la texture du filet 111 est prévue plus fine sans sa partie inférieure. Des ergots de retenue 119 sont prévus sur chaque arceau 113 pour empêcher la reiaontée du filet une fois déployé. En outre, pour le cas où le bord inférieur du filet n'atteindrait pas ces ergots, des dispositifs auto-bloquants sont prévus sur ce bord inférieur. Sur la figure 3, on a représenté le filet 111 entièrement replié sous l'anneau 102. Il est maintenu dans cette position par des crochets déverrouillables actionnés par électro-aimants. Pour utiliser le dispositif, onmouille le radeau avec le filet replié sous l'anneau. Quant l'observation par la caméra 106 montre que la concentration de poisson est suffisante, on relâche les crochets qui maintiennent le filet 111 replié. Sous l'effet des lests 118, le filet descend le long des arceaux 113 et forme une cloche emprisonnant le poisson. Grâce au lest 114, les arceaux conservent une certaine pente au voisinage de leur point de croisement, ce qui permet au filet d'achever convenablement sa descente et de venir s'accrocher sur les ergots 119, en ne laissant qu'une ouverture négligeable en bas de la cloche.To avoid gathering in the vicinity of the crossing point of the rings, the lower edge of the net is threaded on rods 115. Each rod has its ends sliding on two neighboring arches and it is in two parts joined by a joint 116. Thus , when the net is deployed (Figures 4 and 6), these rods force the net to form folds 117 (Figure 4) which avoid puckering. Weights 118 attached to the articulation points 116 ensure that the folds form towards the outside of the cage. In addition, the texture of the net 111 is provided finer without its lower part. Retaining lugs 119 are provided on each arch 113 to prevent the re-assembly of the net once deployed. In addition, for the case where the lower edge of the net does not reach these lugs, self-locking devices are provided on this lower edge. In Figure 3, the net 111 is shown fully folded under the ring 102. It is held in this position by unlockable hooks actuated by electromagnets. To use the device, wet the raft with the net folded under the ring. When the observation by the camera 106 shows that the concentration of fish is sufficient, the hooks which keep the net 111 folded are released. Under the effect of the weights 118, the net descends along the hoops 113 and forms a bell trapping the fish. Thanks to the ballast 114, the hoops retain a certain slope in the vicinity of their crossing point, which allows the net to properly finish its descent and to come to hang on the lugs 119, leaving only a negligible opening in bottom of the bell.
On détache alors l'anneau du filet 111 en relâchant les crochets d'assemblage et on l e r emont e à bord en l e r ep l i ant a pr è s l ' avo ir d égonflé. Il ne reste plus qu'à capturer à l'ëpuisette le poisson contenu dans la cloche qui flotte grâce aux flotteurs 112.The ring of the net 111 is then detached by releasing the assembly hooks and it is re-assembled on board by l e r ep l iant before having the deflated air. It only remains to catch the fish contained in the bell which floats thanks to the 112 floats using a landing net.
On va maintenant décrire, en rëférence aux figures 7 à 9, une seconde réalisation de l'invention.We will now describe, with reference to FIGS. 7 to 9, a second embodiment of the invention.
Un radeau 201 est formé d'un anneau 202 souple et gonflable entourant un filet 203 et une feuille de caoutchouc 204. Sur le pourtour de l'anneau 2 est fixé un filet cylindrique 211 (figure 8) dont le bord inférieur est muni de lests 218. Cette fixation est amovible, étant réalisée au moyen de crochets à commande électromagnétique. Le bord supérieur du filet 211 porte des flotteurs 212 de manière à pouvoir flotter quand l'anneau est séparé du filet.A raft 201 is formed of a flexible and inflatable ring 202 surrounding a net 203 and a rubber sheet 204. On the periphery of the ring 2 is fixed a cylindrical net 211 (FIG. 8) whose bottom edge is provided with weights 218. This fixing is removable, being carried out by means of hooks with electromagnetic control. The upper edge of the net 211 carries floats 212 so that float when the ring is separated from the net.
Une caméra 206 orientable est fixée au filet 203 et disposée pour transmettre, via une antenne 207, une image de la zone située sous le radeau à un récepteur situé sur un navire d'accompagnement.A directional camera 206 is attached to the net 203 and arranged to transmit, via an antenna 207, an image of the area located under the raft to a receiver located on an accompanying ship.
Un cordon 221 est enfilé sur le bord inférieur du filet 211 et présente des extrémités libres de manière à permettre, par traction, la fermeture de la partie inférieure du filet (figure 9).A cord 221 is threaded on the lower edge of the net 211 and has free ends so as to allow, by traction, the closing of the lower part of the net (FIG. 9).
Sur la figure 7, on a représenté le filet 211 entièrement replié sous l'anneau. Il est maintenu dans cette position par des crochets escamotables à commande électromagnétique.In Figure 7, the net 211 is shown fully folded under the ring. It is held in this position by retractable hooks with electromagnetic control.
Pour utiliser le dispositif, on mouille le radeau, puis on observe la concentration du poisson grâce à la caméra 206. Quand cette concentration est jugée suffisante, on libère le bord inférieur du filet 211 qui se déploie suivant la configuration de la figure 2. A partir du navire d'accompagnement et d'un navire auxiliaire, on tire alors sur les extrémités du cordon 221 (figure 9) pour fermer la partie inférieure du filet et enfermer le poisson.To use the device, the raft is wet, then the concentration of the fish is observed using the camera 206. When this concentration is deemed sufficient, the lower edge of the net 211 is released, which unfolds according to the configuration in FIG. 2. A starting from the accompanying vessel and an auxiliary vessel, one then pulls on the ends of the cord 221 (FIG. 9) to close the lower part of the net and to enclose the fish.
Il ne reste plus qu'à désolidariser l'anneau du filet, puis à recueillir le poisson à l'épuisette dans le filet.It only remains to separate the ring from the net, then collect the fish with a landing net in the net.
On va maintenant décrire, en référence aux figures 10 et 11, une troisième variante de réalisation de l'invention.We will now describe, with reference to Figures 10 and 11, a third alternative embodiment of the invention.
Six feuilles de caoutchouc 304 triangulaires sont assemblées avec un sommet commun pour constituer un hexagone régulier. Les côtés communs des feuilles sont assemblés entre eux par laçage, par l'intermédiaire de flotteurs rectilignes radiaux 331 rattachés par des anneaux à un câble circulaire central 332.Six sheets of triangular 304 rubber are assembled with a common top to form a regular hexagon. The common sides of the sheets are joined together by lacing, by by means of radial rectilinear floats 331 attached by rings to a central circular cable 332.
Des flotteurs 302 sont répartis à la périphérie de l'hexagone pour constituer un anneau flottant.Floats 302 are distributed around the periphery of the hexagon to form a floating ring.
A l'extrémité de chaque flotteur rectiligne 331 est fixée l'extrémité d'une chaîne 313 prolongée par un câble 333, et les extrémités de ses câbles sont réunies en un point commun 334 qui, en service normal, est situé sous le centre du dispositif.At the end of each straight float 331 is fixed the end of a chain 313 extended by a cable 333, and the ends of its cables are united at a common point 334 which, in normal service, is located under the center of the device.
Les chaînes 313 et les câbles 333 constituent des arceaux de guidage sur lesquels sont enfilés des anneaux 335 fixés sur un filet 336.The chains 313 and the cables 333 constitute guide hoops on which are threaded rings 335 fixed on a thread 336.
A l'extrémité de chaque flotteur rectiligne 331 est fixée une poulie 337 sur laquelle est engagée un câble de traction 338 fixé par une extrémité en un point du pourtour du filet 336, et muni à son autre extrémité d'un contrepoids 339.At the end of each straight float 331 is fixed a pulley 337 on which is engaged a traction cable 338 fixed by one end at a point around the edge of the net 336, and provided at its other end with a counterweight 339.
On comprend que, tant que les contrepoids 338 sont en position haute, au voisinage des poulies 337, le filet 336 reste replié au voisinage du point de jonction 334 des câbles 333. Quand ces contrepoids descendent par gravité, le filet se déploie le long des chaînes 313 pour constituer une enceinte fermée où le poisson est capturé.It is understood that, as long as the counterweights 338 are in the high position, in the vicinity of the pulleys 337, the net 336 remains folded in the vicinity of the junction point 334 of the cables 333. When these counterweights descend by gravity, the net is deployed along the chains 313 to form a closed enclosure where the fish is caught.
Chaque câble de traction 338 porte, vers son extrémité portant le contrepoids 339, un anneau 341 engagé sur un pêne 342 d'un verrou 343 (figure 12). Ce verrou porte lui-même un anneau 344 grâce auquel il est fixé au flotteur 331.Each traction cable 338 carries, towards its end carrying the counterweight 339, a ring 341 engaged on a bolt 342 of a lock 343 (FIG. 12). This lock itself carries a ring 344 by which it is fixed to the float 331.
Le pêne 342 est solidaire d'un vérin pneumatique 345 relié par une conduite 346 à une bouteille d'air comprimé 347. Les contrepoids 339 étant en position haute, on peut ainsi télécommander la rétraction simultanée de tous les pênes, ce qui provoque le déploiement du filet et la capture du poisson. Un câble axial 348 est attaché au point de jonction 334 des câbles 333, pour donner une forme adéquate au volume de capture. Ce câble sert également à la remontée du filet plein de poissons. Une fois le filet remonté à bord du navire d'accompagnement, on le vide par le procédé connu des déchirures artificielles. Les contrepo ids 339 s ont munis de gal e ts de roulement 349 (figure 13), ce qui facilite les manoeuvres sur le pont du navire.The bolt 342 is integral with a pneumatic cylinder 345 connected by a pipe 346 to a bottle of compressed air 347. The counterweights 339 being in the high position, it is thus possible to remote control the simultaneous retraction of all the bolts, which causes the deployment of the net and the capture of the fish. An axial cable 348 is attached to the junction point 334 of the cables 333, to give an adequate shape to the capture volume. This cable is also used to raise the net full of fish. Once the net is brought back on board the accompanying vessel, it is emptied by the known process of artificial tears. Counterweights 339 s are fitted with rollers 349 (Figure 13), which facilitates maneuvers on the deck of the ship.
Dans le but d'exploiter un vaste banc de poissons, on assemble un certain nombre de dispositifs hexagonaux suivant un pavage régulier 350 (figure 14). On utilise alors une bouteille d'air comprimé commune 351. Un manomètre mesure la pression de l'air comprimé à la sortie de la bouteille et, à chaque fois que cette pression atteint un seuil prédéterminé, ouvre la conduite relative à l'un des hexagones. De cette façon, une fois déclenché le déploiement de l'un des filets, le déploiement des autres suit séquentiellement.In order to exploit a large school of fish, a certain number of hexagonal devices are assembled according to a regular paving 350 (FIG. 14). A common compressed air bottle 351 is then used. A pressure gauge measures the pressure of the compressed air at the outlet of the bottle and, each time this pressure reaches a predetermined threshold, opens the pipe relating to one of the hexagons. In this way, once the deployment of one of the nets has started, the deployment of the others follows sequentially.
Ce déploiement séquentiel a pour but d'éviter que les filets ne s'emmêlent au cours d'un déploiement simultané. Dans toutes les variantes décrites, le rendement de la pêche est fortement amélioré grâce à la concentration artificielle du poisson, et par le fait que les manoeuvres sont simples et rapides.The purpose of this sequential deployment is to prevent the nets from becoming tangled during a simultaneous deployment. In all the variants described, the fishing yield is greatly improved thanks to the artificial concentration of the fish, and by the fact that the maneuvers are simple and rapid.
Bien entendu, l'invention n'est pas limitée aux exemples décrits mais couvre toute va riante technologique à la portée de l'homme de l'art. Of course, the invention is not limited to the examples described but covers all technological laughter within the reach of those skilled in the art.
