| Summary: | The investigations on the growth of Siberian sturgeon and that of the two hybrids of Siberian sturgeon and sterlet was carried out in a recycling system where high stocking density and intensive feeding were applied. In our experimental conditions based on the results it can be assumed that the differences in the growth of the Siberian sturgeon and the hybrids were primarily influenced by the technological-ecological factors and the effect of the different genetical background had only secondary importance. / On a mené des travaux sur la croissance de l'esturgeon Sibérien et celles de ses 2 hybrides avec le sterlet. Les expérimentations ont été réalisées dans un circuit fermé avec des densités de poissons importantes nourris de façon intensive. Dans nos conditions expérimentales et sur la base de nos résultats, on peut admettre que les croissances de l'esturgeon sibérien et de ces 2 hybrides sont principalement influencées par des facteurs technico-écologiques l'influence génétique étant secondaire. |
