Identification of the sex of sturgeon

The sturgeons are critically endangered. Given this situation, aquaculture has emerged as the only solution to the depopulation and farm structures develop around the world to raise sturgeon in order to release them in the middle. Of course, these farms can produce caviar necessary to satisfy the growing consumer demand, the wild caviar is becoming increasingly scarce and subject to strict quotas. For some species like the Siberian sturgeon or A. gueldenstaedtii, livestock is well controlled, even if it is not optimized. The lock technology, which has been identified by the farmers themselves on the stage of sexing individuals. This step, which occurs after 3 to 7 years depending on livestock species, allows them to separate males from females who are the only ones to be preserved and even elevated for 4 to 10 years for the production of caviar. It is now necessary to raise the same manner all individuals for at least three years to finally remove the half. It is a significant loss of time and money, making the economy vulnerable. The project presented here aims to validate and eventually to market a molecular technique for identifying the sex of sturgeon have few weeks of life, thus enabling a much earlier sexing fish. This technique will be performed within a company to create (AquaDN) after a research team (Team Marine Molecular Biology - Laboratory Protee - Université du Sud
