Title
(EN) METHOD FOR COMMERCIAL EDIBLE FISH BREEDING OF EUROASIAN PIKE-PERCH
(FR) PROCEDE D'ELEVAGE COMMERCIAL DE POISSON COMESTIBLE APPLIQUE AU SANDRE D'EURASIE
Abstract
(EN) The present invention relates to a method for commercial edible fish rearing of Euro-asiatic pike-perch, Stitzostedion lucioperca. By means of the method the intestinal system of the pike-perch is made to accept and to assimilate the energy in a dry feed. This is done in that mature, fertilised pike-perch spawn is released into a hatching tank containing rotifera, where it is allowed to hatch, following which a smaller quantity of Cladocera and Copepoda is added to the hatching tank. The pike-perch is thereafter allowed to feed in the hatching tank, initially on rotifera and then on Cladocera and Copepoda, until the pike-perch larvae have left the larva stage and passed to a fry stage and reached a length of approximately 25-35 mm, following which the fry are transferred to a rearing tank. In the rearing tank accustomisation to dry feed is begun, following which rearing to a stage at which the fish are ready for killing is undertaken with dry feed as the sole source of nutrition for the fish.
(FR) Cette invention concerne un procédé d'élevage commercial de poisson comestible appliqué au sandre d'Eurasie, Stitzostedion lucioperca. Ce procédé permet de forcer le système intestinal du sandre à accepter et à assimiler l'énergie contenue dans de la nourriture sèche. Pour cela, on répand du frai de sandre mature fertilisé à l'intérieur d'un bassin à éclosion situé dans un endroit où l'élevage est autorisé et contenant des rotifères. On ajoute ensuite dans le bassin une plus petite quantité de cladocères et de copépodes. Dans le bassin à éclosion, les sandres peuvent alors se nourrir, tout d'abord de rotifères, puis de cladocères et de copépodes, jusqu'à ce que les larves de sandres quittent l'état larvaire et passent à l'état d'alevin pour atteindre une taille d'environ 25 à 35 mm, après quoi les alevins sont transférés dans un bassin d'élevage. A l'intérieur du bassin d'élevage, la phase d'adaptation à la nourriture sèche commence pour arriver à une étape où le poisson ne dispose plus que de nourriture sèche pour vivre, étape à partir de laquelle il pourra alors être tué.
