Culturally we have always considered fish to be animals very different from us, so much so that even today they are the only animals that can be hunted in a protected area. Something is changing and in recent years there has also been an interest in local forms, genetically distinct from populations of other valleys if sufficiently isolated over time. This aspect also contributes to increasing the biodiversity of a natural environment and slowly local strains are being selected which, at least in their livery, are distinguished from the typical shape of the brown trout.
