Description
Summary:The term has a legislative meaning when it applies to species submitted to selection pressures, but also a literary one, according to the time since which the species live closed to men and the possibility of controlling their reproduction. In terms of legislation, none of both species of gadids object of this article, cod and pollack, can be considered as domestic. From a literary point of view, 140 years of research and the control of the reproduction, give to the cod a domestic status. It is not the case with pollack, only studied since ten years and the reproduction of which is still badly controlled. The weak differences observed between the performances of breeding and wild cods focus the still limited impact of the domestication on this species. Thanks to its aquaculture development in the North Europe and America, fish farming techniques as well as selection programs should be available, facilitating the cod to reach a domestic status such as considered by the legislator.Original Abstract: Le terme domestication possede un sens legislatif, attribuable a des especes qui ont fait l'objet de pressions de selection, mais aussi un sens litteraire, prenant en compte le temps depuis lequel l'espece vit aupres de l'homme et la possibilite de controler sa reproduction. Selon le premier sens de ce terme, aucune des deux especes de gadides qui font l'objet de cet article, la morue et le lieu jaune, ne peut etre consideree comme domestique. D'un point de vue litteraire, les travaux de recherche menes depuis 140 ans sur la morue et le controle fin de sa reproduction accordent a cette espece le statut de domestique. C'est plus difficilement le cas du lieu jaune chez lequel les travaux ont debute il y a dix ans et dont la reproduction est encore mal maitrisee. Les faibles differences observees entre les performances de morues d'elevage et sauvages mettent en evidence l'impact encore limite de ce processus chez cette espece. Grace a l'interet porte a son elevage dans le nord de l'Europe et de l'Amerique, des techniques d'aquaculture mais egalement des programmes de selection devraient etre disponibles, facilitant l'accession de la morue au statut de domestique, tel que l'entend le legislateur.
