The genetic analyzes of the first year of the project had revealed, in some peripheral basins of the Volturno River, the presence of resident (non-migratory) populations with a discrete component of indigenous genetics.
We are now continuing these investigations to discover, before the breeding season, the possible presence of pure source populations to be used for artificial reproduction practices aimed at egg production. These eggs could be specifically destined for the repopulation of the minor peripheral watercourses, some more or less isolated from the main Volturno system.
