Molecular characterization and hybridization in Salmo (trutta) macrostigma morphotypes from Central Italy
The super-species Salmo trutta is taxonomically divided into a number of semi-species, local varieties, morphs, and possible hybrids due to restocking. Their genetic status is nevertheless not always clear, although relevant for management and conservation practices. We used mitochondrial haplotypes...

The super-species Salmo trutta is taxonomically divided into a number of semi-species, local varieties, morphs, and possible hybrids due to restocking.
