FERME SOUS-MARINE
Chéation d'une jerme sous-marine consistant à fixer d'une manière artificielle les esp8ces de poissons de mer existant dans leur milieu naturel.UNDERWATER FARM
Cheatation of an underwater jerm consisting in artificially fixing the species of sea fish existing in their natural environment.
Ce procédé se différencie fondamentalement de l'aquaculture puisqu'il ne s'agit nullement d'un éleuage clos. mais d'une fixation en lieu précis de la faune et de la flore en mer libre.This process differs fundamentally from aquaculture since it is by no means a closed stump. but of a fixed location of the fauna and flora in the open sea.
Ce projet a pour finalité immédiate un aspect scientifique, culturel, touristique, sous la forme de création d'un parc naturel, non commercial, mais pouvant déboucher sur une exploitation par la péche professionnelle.This immediate purpose of this project has a scientific, cultural and tourist aspect, in the form of the creation of a natural, non-commercial park, which could lead to exploitation by professional fishing.
Il consiste à reproduire un "mini émissaire" a rejet parfaitement contrôlé dans un enrochement artificiel afin de favoriser la fixation de la faune dans son milieu naturel.It consists in reproducing a "mini outlet" with perfectly controlled discharge in an artificial riprap in order to favor the fixation of the fauna in its natural environment.
La ferme sous-marine se différencie de la technique antérieure employée à ce jour en matière d'aquaculture laquelle consiste essentiellement en un élevage de poissons à partir d'alevins mis dans un endroit clos, jusqu'à ce qu'ils atteignent la taille requise permettant leur commercialisation.The underwater farm differs from the previous technique used to date in aquaculture which essentially consists of raising fish from fry placed in an enclosed area, until they reach the required size allowing their marketing.
Cette façon de procéder restreint considérablement la mise à disposition des espèces sur le marché puisqu'elle s'adresse, pour le moment, à quelques variétés de poissons susceptibles d'être élevés de cette manière.This procedure considerably restricts the availability of species on the market since it is intended, for the moment, for a few varieties of fish likely to be reared in this way.
Au contraine, la ferme sous-marine implantée dans un endroit donné choisi par des spécialistes, et sous le contrôle de scientifiques, s'adresse directement et immédiatement aux espèces déjà sur place, avec la possibilité d'attinen d'autres variétés non sédentaines.On the other hand, the underwater farm located in a given location chosen by specialists, and under the supervision of scientists, directly and immediately addresses species already on the spot, with the possibility of attacking other non-sedentary varieties.
En outre, le contrôle effectué par les scientifiques doit permettre l'étude du comportement de cette faune et sa capacité de fixation à l'aide d'ariments appropriés, judicieusement dosés, et injectés sur le site désigné.In addition, the control carried out by the scientists must allow the study of the behavior of this fauna and its capacity of fixation using appropriate food, judiciously dosed, and injected on the designated site.
Cette étude peut également déboucher sur une éventuelle fixation d'autres espéces et notamment des migrateurs ceci en fonction dje la modification éventuelle de al flore existante.This study can also lead to a possible fixation of other species and in particular of migrants this depending on the possible modification of the existing flora.
Planifiée sur AU moins trois ans, elle est donc susceptible d'apporter des solutions au dépeuplement des esp8ces notamment cotiéres et sédentaires, et par là même de relancer la péche artisanale actuellement en période de déclin à la suite du manque de possons constaté aux abords des côtes de notre région.Planned over at least three years, it is therefore likely to provide solutions to the depopulation of species, especially coastal and sedentary species, and thereby to revive artisanal fishing currently in decline due to the lack of opportunities found around coasts of our region.
La ferme sous-marine est composée d'enrochements sous la forme de quatre massifs en bêton alvéolé, fixés sur un cadre m6tallique. lui-méme ancré sur le fond de la mer. The submarine farm is made up of riprap in the form of four solid concrete blocks, fixed on a metal frame. itself anchored on the bottom of the sea.
Elle est reliée à la station à terre pr une liaison ombilienle.It is connected to the shore station for an umbilical link.
la station à rerre comprend un obri au dispositif qui permet l'injection de la nourriture à l'aide d'eau sous pression. Elle comprend trois parties principales : - focal technique équipé d'un dispositig d'injection, - focal entrepôt pour la nourriture.the wand station includes a cover to the device which allows food to be injected using pressurized water. It has three main parts: - technical focal point equipped with an injection device, - warehouse focal point for food.
- focal destin6 à l'étude ainsi que des sanitaines.- focal point for study as well as sanitaries.
L'injection d'aliments est effectuée au moyen de l'eau douce, son fonctionnement est automatique, à cadences déterminées par les scientifiques, il en sera de même pour le choix de la nounniture.The injection of food is carried out using fresh water, its operation is automatic, at rates determined by scientists, it will be the same for the choice of nounniture.
