Abstract
Description
La pressente invention concerne un dispositif pour l'élevage des écrevisses en milieu fermi et artificiel. The present invention relates to a device for raising crayfish in a closed and artificial environment.
Afin d'exercer un control permanent du grossissement des juviniles,de la reproduction des géniteurs.La méthode la plus simple,pour une consommation d' eau minimum, un gain de place endorme. In order to exercise permanent control of the magnification of the juveniles, of the reproduction of the parents. The simplest method, for a minimum consumption of water, saves sleeping space.
I1 permet de crier un milieu adéquate pour l'espèce eleve'e.changement de P.H.,rigulation de la tempirature,D.B.O ,nourriture suivant les besoins réels. It makes it possible to shout an adequate environment for the high species. Change of P.H., temperature rigidity, D.B.O, food according to real needs.
Le dispositif selon l'invention,permet de remédier à tous problémes,dans les diluais les plus brefs.Il comporte en effet selon une première caractéristi que,un filtre compartimenté (fig 2) avec un mouvement d'eau à partir d'eflauti ons,dibit réglable à partir de robinets sur le circuit d'air,fournit par un surpresseur. The device according to the invention makes it possible to remedy all problems, in the shortest dilutes. It indeed has, according to a first characteristic, a compartmentalized filter (fig 2) with a movement of water from efflauti ons , adjustable dibit from valves on the air circuit, supplied by a booster.
un premier compartiment étanche,reçoit l'eau à filtrer.Compartiment planté d'especes,tels que "Topamogéton crispus,Elodea ,en surface "Trappa natan
Papyrus".peuplé de daphnies.l'eau est renvoyée dans le deuxiéme compartiment.a first sealed compartment, receives the water to be filtered. Compartment planted with species, such as "Topamogeton crispus, Elodea, on the surface" Trappa natan
Papyrus ". Populated with daphnia. Water is returned to the second compartment.
deuxième compartiment en communication constante avec le troisiéme par la masse filtrante inférieur,présentement du gravier.Sur une hauteur de 60 cl, cette masse filtrante ,plantée,et peuplée,est traversée par l'eau qui rejoint le troisième compartiment. second compartment in constant communication with the third by the lower filter mass, currently gravel. At a height of 60 cl, this filter mass, planted and populated, is crossed by the water which joins the third compartment.
troisième compartiment,son eau y traverse un premier filtre à base de "perlon" (2)qui affine le filtrage De nouveau un filtre à algues (3) en surface.le mouvement d'eau est permis gràce à la paroi du quatriéme compartime nt,légérement inférieure au niveau d'eau du filtre. third compartment, its water passes through a first filter based on "perlon" (2) which refines the filtering Again an algae filter (3) on the surface. the movement of water is allowed thanks to the wall of the fourth compartment nt , slightly below the water level of the filter.
quatriéme compartiment,renvoi l'eau dans les bac de grossissement par le systéme des vases communiquants (fig 3)
L'eau contenue dans le filtre,est chauffée gràce à une résistance,régulée.fourth compartment, returns water to the magnification tanks by the system of communicating vessels (fig 3)
The water contained in the filter is heated by a regulated resistance.
de 09 à 300 ,et de puissance 3000w.un éclairage néon horticole,est placée au dessus du filtre à algues,afin de palier le manque d'éclairage naturel.from 09 to 300, and 3000w power. a neon horticultural lighting is placed above the algae filter, to compensate for the lack of natural lighting.
un fond incliné (5)permet la récupération de la sédimentation du filtre. an inclined bottom (5) allows the recovery of the sedimentation of the filter.
et par la même la vidange partielle du filtre pour un renouvellement d'eau.and at the same time partial emptying of the filter for water renewal.
l'eau étant prise dans un bac de réserve,eau épurée par une plantation et un peuplement de daphnies.Réserve qui peut être utilisée en cas de changement intempestif d'eau.the water being taken in a reserve tank, water purified by a plantation and a stand of daphnia. Reserve which can be used in the event of untimely change of water.
en sortie de filtre l'eau s'écoule vers les bacs de grossissement et de reproductions (fig 3) le nombre de bacs n'est pas exhaustif,il dépend simplement du volume du filtre. at the filter outlet the water flows to the magnification and reproduction tanks (fig 3) the number of tanks is not exhaustive, it simply depends on the volume of the filter.
Les bacs 2mx @m sur une hauteur de 60 cl, ont leur propre filtre sous gravier (fig 4) ils peuvent donc être rendus indépendants. le fond du bac en pl an incliné reçoit la sédimentation qui peut donc te vidangé réguliérement
Une grille (6) de maintient,rend le fond plat,un filtre tubulaire (tig 4) avec 6 exhausteurs y est déposé1 et recouvert d'une couche degravier de I5 cm. se filtre simple et efficace permet la circulation de l'eau à travers le sable il maintient donc une D.B.0. optimum. ces bacs sont plantés et peuplés les abris déposés dans le fond du bac ,en surnombre permettent de sécuriser les écrevisses.Un floteur maintient les plantes de surface sur le pourtour du bac 3' ,un îlot central permet aux écrevisses de sortir de l'eau suivant le nombre,il est facile de determiner si les écrevisses sont bien dans leur élément sous les 6 exhausteurs un filtre à algues y est installai. The 2mx @m tanks over a height of 60 cl have their own gravel filter (fig 4) so they can be made independent. the bottom of the inclined pan receives sedimentation which can therefore drain you regularly
A retaining grid (6) makes the bottom flat, a tubular filter (tig 4) with 6 enhancers is placed there1 and covered with a gravel layer of 15 cm. simple and efficient filter allows water circulation through the sand so it maintains a BOD. optimum. these tanks are planted and populated, the shelters placed in the bottom of the tank, in excess allow the crayfish to be secured. A float keeps the surface plants around the edge of the 3 'tank, a central island allows the crayfish to come out of the water according to the number, it is easy to determine if the crayfish are well in their element under the 6 enhancers an algae filter is installed there.
