Abstract
Description
La présente invention concerne un dispositif permettant d'améliorer laThe present invention relates to a device for improving the
qualité des huîtres dans les bassins ou claires d'affinage, et de faciliter le travail de l'homme. quality of oysters in basins or clear ripening, and facilitate the work of man.
Traditionnellement la culture des huîtres est effectuée par semée à la volée dans des bassins d'eau salée dits marais, ce qui engendre un risque de mauvais positionnement de l'huître s à sa retombée sur le sol, provoque l'éventuel enfouissement de l'huître dans la vase et nécessite l'apprentissage de cette technique très spécifique de la semée à la volée. Ce procédé est physiquement très éprouvant en raison de la manutention et de l'utilisation de beaucoup de petits matériels. Traditionally oyster culture is carried out by sowing in salt water basins called marshes, which creates a risk of misplacement of the oyster s to its fall on the ground, causes the eventual burial of the oyster in the vase and requires learning this very specific technique of sowing on the fly. This process is physically very demanding because of the handling and use of many small equipment.
Une autre méthode consiste à déposer une par une les huîtres sur le sol, ce qui est très 10 laborieux, ne garantit pas un maintien durable de l'huître dans sa position initiale et n'empêche pas l'éventuel enfouissement de l'huître dans la vase. Another method is to deposit the oysters one by one on the ground, which is very laborious, does not guarantee a sustainable maintenance of the oyster in its initial position and does not prevent the possible burying of the oyster in the vase.
Selon la culture traditionnelle, la récolte de la production d'huître est effectuée par ramassage à la fourche puis mise en mannes. Ce procédé est long et nécessite beaucoup de petits matériels utiles, mais ne garantit pas une repêche complète de la production qui peut être envasée ou bien très éparpillée dans les bassins. According to traditional culture, oyster production is harvested by forklifting and then manhandled. This process is long and requires a lot of useful small equipment, but does not guarantee a complete recovery of the production that can be silted or very scattered in the basins.
Selon les méthodes de culture traditionnelle lors d'éventuels dépôts d'algues sur le fond du bassin, il y a risque de perte de la production d'huîtres qui est menacée d'asphyxie. Lors d'éventuelles nécessités de changement de claire, par exemple pour saumurer, le travail est long et laborieux. According to the traditional farming methods during possible algae deposits on the bottom of the basin, there is a risk of loss of oyster production which is threatened with asphyxiation. When there is a need for a clear change, for example to brine, the work is long and laborious.
Le dispositif selon l'invention permet de remédier à ces inconvénients. Il consiste en effet, selon une première caractéristique, à coller les huîtres sur un treillis en nylon à l'aide de plots de crème de mortier au niveau de leur coquille inférieure, côté creux, ce qui permet de garantir un bon et durable positionnement des huîtres dans les bassins, et n'implique qu'une manipulation simple et rapide lors de la mise à l'eau de l'huître et de sa sortie. Cette technique ne demande ni matériel, ni effort particulier. The device according to the invention overcomes these disadvantages. It consists in fact, according to a first characteristic, to stick the oysters on a nylon mesh with mortar cream pads at their lower shell, hollow side, which ensures a good and durable positioning of the oysters in basins, and involves only simple and quick handling when launching the oyster and its release. This technique requires neither material nor special effort.
Les dessins annexés illustrent l'invention: La figure 1 représente une coupe horizontale. The accompanying drawings illustrate the invention: Figure 1 shows a horizontal section.
La figure 2 représente une vue de dessus globale. Figure 2 shows an overall top view.
La figure 3 représente une vue de dessus précise. Figure 3 shows a precise top view.
En référence à ces dessins, le dispositif comporte un treillis en nylon (1) sur lequel, à espacements réguliers, sont disposés des plots de crème de mortier (2) où l'on colle les huîtres (3) pour être ensuite immergé dans les bassins. Les huîtres (3) solidement fixées par le plot de crème de mortier (2) au treillis (1) ne risque plus l'enfouissement dans la vase (4), ce qui est souvent la cause de taches à l'intérieur de la coquille de l'huître (3), tout en éliminant tout risque de dispersion des huîtres (3). Le treillis (1) servant de support fait office de patin et réduit encore le risque d'envasement des huîtres (3). With reference to these drawings, the device comprises a nylon mesh (1) on which, at regular spacings, are placed blocks of mortar cream (2) where the oysters (3) are then glued to be immersed in the basins. The oysters (3) securely fixed by the mortar cream pad (2) to the mesh (1) no longer risk burying it in the vase (4), which is often the cause of stains inside the shell oyster (3), while eliminating any risk of oyster dispersal (3). The trellis (1) serves as a support pad and further reduces the risk of siltation of oysters (3).
Le dispositif composé d'un treillis en nylon (1) est placé sur le fond vaseux (4) du bassin ou claire d'affinage, les huîtres (3) fixées au treillis (1) par le plot de crème de mortier (2) restent dans une position idéale pour un parfait développement des mollusques et de leurs coquilles. The device consisting of a nylon mesh (1) is placed on the muddy bottom (4) of the pond or clear ripening, the oysters (3) fixed to the mesh (1) by the mortar cream pad (2) remain in an ideal position for perfect development of molluscs and their shells.
ainsi idéalement positionnées, elles filtrent constamment pour se nourrir, ce qui augment l'indice de qualité de la chaire de l'huître (1). Les huîtres (3) maintenues au treillis (1) dans cette position optimale pour croître, développent alors une coquille plus dure et plus régulière. thus ideally positioned, they filter constantly for food, which increases the quality index of the oyster pulpit (1). The oysters (3) held in the lattice (1) in this optimal position to grow, then develop a shell more hard and more regular.
Le dispositif, comportant un treillis (1) sur lequel sont collées des huîtres (3) par un plot de crème de mortier (2) permet également une manipulation rapide de la production: le treillis 10 (1) pouvant supporter des dizaines d'huîtres (3). The device, comprising a mesh (1) on which oysters (3) are glued by a mortar cream pad (2) also allows a quick manipulation of the production: the mesh 10 (1) can support dozens of oysters (3).
Le dispositif simplifie considérablement la manipulation de la production d'huîtres: le treillis pouvant être transporté par simple glissement sur le sol. The device greatly simplifies the handling of oyster production: the mesh can be transported by simply sliding on the ground.
A titre d'exemple non limitatif, le treillis en nylon (1) aurait des dimensions de l'ordre de 5 m de longueur et de 30 cm de largeur; les plots de crème de mortier (2) seraient espacés de 15 15 cm, sur lesquels seraient collées au maximum trois huîtres. By way of non-limiting example, the nylon mesh (1) would have dimensions of the order of 5 m in length and 30 cm in width; the plots of mortar cream (2) would be spaced 15 cm apart, on which would be glued a maximum of three oysters.
Le dispositif selon l'invention est donc particulièrement destiné à améliorer les conditions de la production et la qualité des huîtres dans les bassins ou claires d'affinage. The device according to the invention is therefore particularly intended to improve the conditions of production and quality of oysters in basins or clearing refining.
