Recent Taxonomic Discoveries Concerning the Genus Mytilus in the Adriatic Sea: Implications for Biomonitoring

Mussels Mytilus spp. belong to a group of key species in coastal marine ecosystems. This work demonstrates the dominant presence of Mediterranean mussel M. galloprovincialis along eastern Adriatic coast. Morphometric characteristics of sampled mussels were inside normal values for M. galloprovincialis, with a height/lenght ratio of 55.89 ± 5.08 % and a width/length ratio of 38.76 ± 3.42 %. Populations of Croatian Adriatic Sea were nearly fixed for the G allele at the Me 15/16 locus as it is usually observed with M. galloprovincialis samples. However, two specimens among the 110 analysed showed a heterozygote genotype: one with an E (M. edulis) allele and one witj a T (M. trossulus) allele. By sequencing PCR products we proved that the 126 bp, 168 bp and 180 bp bands correspond to the G, T and E alleles previously reported.
