ABSTRACT The concentrations of the trace elements zinc (Zn), arsenic (As), manganese (Mn), copper (Cu), chromium (Cr), nickel (Ni), cobalt (Co), cadmium (Cd), lead (Pb), mercury (Hg), and iron (Fe) were examined in Mediterranean blue mussels (Mytilus galloprovincialis) from the Northern Adriatic Sea to determine whether there were site differences and seasonal variations in metal concentrations and to evaluate the potential health risks of consumption of these mussels to humans. Mussels were collected between January and October 2015 from three Slovenian shellfish harvesting areas and from a lighthouse near Debeli Rtič. The concentrations of elements were determined using inductively coupled plasma mass spectrometry. The amount of each element decreased in the following order: Fe > Zn > (As, Mn) > (Cu, Cr) > (Ni, Co) > (Cd, Pb) > Hg. Statistical analysis revealed that time, that is, the month of sampling, significantly affected the concentrations of elements in mussels (P < 0.05). The concentrations of Cr, Mn, Fe, Ni, Hg, and Pb were highest between January and March and lowest between May and September. The concentrations of other elements in mussels were not higher or lower for several consecutive months, but occasionally (some months) lower or higher content was detected. The sampling site had a statistically significant effect only on the content of Cd, Pb, and Hg in mussels (P < 0.05). The lowest level of these elements was found in mussels from Seča, and the highest levels of Hg and Pb were found in mussels from Debeli Rtič. Debeli Rtič is, among all sampling points, closest to the outflow of the Soča River that brings heavy metals into the Northern Adriatic Sea from a closed Hg mine. Because the concentrations of Pb, Cd, and Hg in all analyzed samples were below the maximum level permitted by Commission Regulation No 1881/2006, mussels were suitable for human consumption.

Investigation of parasites and diseases affecting molluscs of ecological and economic interest is critical for the management of native stocks and aquaculture. In recent years, much attention has been devoted to investigating the World Organisation for Animal Health listed infectious diseases, so that communities can be prepared to attend public health emergencies and avoid severe income losses. In this context, the health status of Mytilus galloprovincialis Lamarck, 1819 was analysed in two aquaculture sites (Strunjan Bay and Piran Bay, Slovenia), and in four natural mussel beds (Adriatic Croatia International Marinas Pula and Rovinj and St Catherine, Croatia; Marina Koper, Slovenia) along the coast of the northern Adriatic Sea. The mussels were sampled in February and April 2014, and processed for histological examination of several endosymbionts and pathogens that frequently occur in mytilid mussels. Endosymbionts and pathogens were not detected in farmed mussels. Prokaryotic inclusion bodies, the protozoan Nematopsis, Ancistrocoma-like ciliates, haplosporidian-like plasmodia, turbellarian Urastoma cyprinae, and basophilic inclusion bodies were observed in digestive gland cryosections of wild mussels from the coastal region of the northern Adriatic. Fungal spores of Psilocybe sp., Ulocladium sp. and Alternaria sp. were detected between the digestive tubules based on their morphology. Diagnostic PCR did not reveal infection with Marteilia refringens during the studied period, neither in wild nor farmed mussels. We confirmed the site effects on prevalence of infected mussels. Thus, we can conclude that wild areas are more exposed to endobionts and parasites than aquaculture sites.

The ability of mussels to cope with environmental conditions depends on the species’ capacity to acclimate or adapt within its morphometric and physiological parameters. In the present study,we investigated the effect of aquaculture site and translocation on different stocks of Mediterranean mussel, Mytilus galloprovincialis Lamarck, 1819. We used shell morphological ratios (width/length, height/length and height/width) and allometric relationships (volume-length and shell weight-length) in addition to condition index (wet meat weight/total weight) and mortality to compare cultivated and translocated mussels from the northern Adriatic Sea, Croatia. Mussels were collected from five cultivation areas (Lim, Pomer, Raša, Vabriga and Budava), and then moved for three months to experimental station at marine protected area in Lim Bay. Differences between cultivated mussels suggested morphological plasticity, although translocation weakly affected allometric relationships. Decrease in condition index was pronounced in translocated mussels, indicating adaptation to different local environmental conditions. High post translocation mortality was observed in mussels transferred to the experimental area. Our study shows plastic response of M. galloprovincialis, which can provide a useful information of mussel stocks selection in aquaculture.
