Can sturgeon be used to feed and eat hybrid sturgeon? .

If the hybrid sturgeon has the same advantages as both parents, almost all sturgeon species can be hybridized to obtain hybrid sturgeon. The most commonly used species are ACIPENSER europaeus, ACIPENSER schrenckii, ACIPENSER Dalbergiae and ACIPENSER sinensis, but the fertilized eggs obtained by crossing with other species cannot hatch successfully, which may be due to the reproductive isolation between ACIPENSER schrenckii and other species. If two varieties cross, if fertilized eggs can be obtained and hatched successfully, only these two varieties cross within the species or a small number cross within the genus.
