Primary Research Paper


The phylogenetic status of brown trout Salmo trutta L 1758 in Sicily is uncertain as some reports describe these trout as S. macrostigma or S. cettii on one hand while other, contradictory reports imply a hatchery origin on the other. In order to clarify this situation, we performed sequence analysis of the mtDNA control region and restriction fragment analysis of the nuclear lactate dehydrogenase (LDH-C1*) gene. A single mitochondrial haplotype (At-s6) found previously in brown trout in Morocco, and two alleles at LDH-C1* (the ancestral*100, at a high frequency, and *90) were revealed. Our results suggest that Sicilian brown trout are native and that they probably colonized Sicily from west to east in an expansion, from the Atlantic Ocean basin, along the North-West African coast.
