Survey of genetic diversity is essential for breeding program. The genetic diversity of A. andreanum, 10 cultivars were analyzed using seven Start Codon Targeted (SCoT) and 40 RAPD markers in which 22 RAPD markers and all of SCoT marker produced polymorphic bands. Matrix genetic distance ranged from 0.01 to 0.37 for RAPD and from 0.02 to 0.52 for SCoT marker analysis. Polymorphism percentage ge...

Acipenser stellatus (stellate sturgeon) represents a sturgeon species of great importance for the scientific community and fishermen that has been intensively captured for decades. Besides of overfishing and poaching, their reproduction sites have been destroyed and their natural habitats were affected by pollution. In consequence, wild populations of stellate sturgeon have decreased dramatical...
