Abstract
Description
La présente invention concerne un dispositif pour le captage et l'élevage des coquillages. The present invention relates to a device for catching and raising shellfish.
On sait que les larves de coquillages, par exemple dthuStres, sont captées par des collecteurs sur lesquels elles commencent à se développer. Au bout d'un certain temps, lorsque le naissain a atteint une taille suffisante, il est détaché de ces collecteurs et placé dans des poches ostréicoles. We know that shellfish larvae, for example dthuStres, are collected by collectors on which they begin to develop. After a certain time, when the spat has reached a sufficient size, it is detached from these collectors and placed in oyster pockets.
Cette opération de détroquage est assez délicate à réaliser, d'autant plus que l'on souhaite généralement obtenir les jeunes coquillages un à un, et non pas assemblés en paquets. This unhooking operation is quite delicate to carry out, especially since it is generally desired to obtain the young shells one by one, and not assembled in bundles.
La présente invention vise à fournir un dispositif de captage de coquillages permettant de faciliter le détroquage tout en obtenant des coquillages séparés un à un. The present invention aims to provide a shell-catching device making it possible to facilitate unhooking while obtaining separate shells one by one.
A cet effet, l'invention a pour objet un dispositif pour le captage et l'élevage des coquillages, caractérisé par le fait qu'il comprend un premier élément présentant une surface relativement rigide sur laquelle est disposé de façon amovible un deuxième élément se présentant sous la forme d'un filet. To this end, the subject of the invention is a device for catching and raising shellfish, characterized in that it comprises a first element having a relatively rigid surface on which a second element having in the form of a net.
Les coquillages se fixent essentiellement sur la surface rigide du premier élément, de sorte que, lorsque les deux éléments sont séparés l'un de l'autre, les coquillages sont détachés individuellement du collecteur. The shells are essentially fixed on the rigid surface of the first element, so that, when the two elements are separated from each other, the shells are detached individually from the collector.
Plus particulièrement, le premier élément peut être un tube et le deuxième élément un filet tubulaire. More particularly, the first element may be a tube and the second element a tubular net.
En outre, des moyens de fixation peuvent être prévus pour fixer le deuxième élément au premier élément. In addition, fixing means can be provided for fixing the second element to the first element.
Dans le cas où le dispositif présente une forme allongée, par exemple dans le cas d'un dispositif tubulaire, il peut, dans un premier mode d'utilisation, être disposé horizontalement sur une table ostréicole. In the case where the device has an elongated shape, for example in the case of a tubular device, it can, in a first mode of use, be arranged horizontally on an oyster table.
Toutefois, dans un deuxième mode d'utilisation, le dispositif peut être disposé verticalement entre un flotteur et un lest. However, in a second mode of use, the device can be arranged vertically between a float and a ballast.
On décrira maintenant à titre d'exemple non limitatif, un dispositif selon l'invention dans les deux modes d'utilisation précités. We will now describe by way of nonlimiting example, a device according to the invention in the two aforementioned modes of use.
Aux dessins schématiques annexés
- la figure 1 représente un dispositif selon l'invention dans un premier mode d'utilisation et,
- la figure 2 représente un dispositif selon l'invention dans un deuxième mode d'utilisation.To the attached schematic drawings
FIG. 1 represents a device according to the invention in a first mode of use and,
- Figure 2 shows a device according to the invention in a second mode of use.
Le dispositif selon l'invention comprend ici un premier élément 1 tubulaire enveloppé dans un deuxième élément 2 constitué par un filet tubulaire. The device according to the invention here comprises a first tubular element 1 wrapped in a second element 2 constituted by a tubular net.
Le tube 1 peut être en matière plastique, par exemple en polypropylène extrudé relativement rigide, et sa surface extérieure peut être suivant le cas, lisse ou rugueuse ou encore comprendre des rainures longitudinaes ou circonférentielles. Le tube 1 peut toutefois être réalisé dans un matériau autre que la matière plastique. The tube 1 can be made of plastic, for example made of relatively rigid extruded polypropylene, and its external surface can be, as the case may be, smooth or rough or even comprise longitudinal or circumferential grooves. The tube 1 can however be made of a material other than plastic.
Le filet 2 peut présenter des mailles de toutes formes convenables, par exemple hexagonales, carrées ou rondes et être réalisé par exemple en matière plastique extrudée. The net 2 can have meshes of any suitable shape, for example hexagonal, square or round and be made for example of extruded plastic.
Le filet 2 peut avoir à l'état naturel, un diamètre sensiblement égal à celui du tube 1 ou encore comme cela est représenté sur les dessins, un diamètre inférieur, auquel cas, il est engagé sur le tube dans un état étiré. The thread 2 may have in its natural state, a diameter substantially equal to that of the tube 1 or, as shown in the drawings, a smaller diameter, in which case, it is engaged on the tube in a stretched state.
Dans la figure 1, on voit le dispositif selon l'invention disposé sensiblement horizontalement sur les éléments 3 d'une table ostréicole. In Figure 1, we see the device according to the invention arranged substantially horizontally on the elements 3 of an oyster table.
Dans le cas de la figure 2, le dispositif selon l'invention est disposé verticalement. In the case of Figure 2, the device according to the invention is arranged vertically.
Une corde 4 a une de ses extrémités fixée à un flotteur 5 et passe à l'intérieur du tube 1. A sa partie inférieure, cette corde est fixée à un lest 6, par exemple à une barre de fer, qui d'une part assure la verticalité du dispositif et d'autre part, assure la liaison de la corde 4 au tube. A rope 4 has one of its ends fixed to a float 5 and passes inside the tube 1. At its lower part, this rope is fixed to a ballast 6, for example to an iron bar, which on the one hand ensures the verticality of the device and on the other hand, ensures the connection of the cord 4 to the tube.
On voit en outre dans la figure 2 que le filet 2 est fixé au tube 1, dans le cas présent à l'aide d'une bande élastique 7. It can also be seen in FIG. 2 that the net 2 is fixed to the tube 1, in this case using an elastic band 7.
Le dispositif selon l'invention étant immergé par exemple, d'une des manières représentées aux figures 1 et 2, les larves de coquillages vont se fixer sur le tube 1 de sorte que, lorsque le filet 2 est ultérieurement retiré du tube, il provoque le détachement des jeunes coquillages qui se trouvent séparés les uns des autres. The device according to the invention being immersed for example, in one of the ways shown in FIGS. 1 and 2, the shell larvae will be fixed on the tube 1 so that, when the net 2 is subsequently removed from the tube, it causes the detachment of young shells which are separated from each other.
Diverses variantes et modifications peuvent bien entendu être apportées à la description qui précède sans sortir pour autant du cadre, ni de l'esprit de l'invention. Various variants and modifications can of course be made to the above description without departing from the scope or the spirit of the invention.
