A multidisciplinary approach was used to estimate the pollution level of the marine environment in the North Eastern Adriatic by measurement of the isotopic composition of carbon and nitrogen (%13C, %15N), metal/metalloids analyses (Fe, Cu, Zn, As, Se, Cd and Pb, including As speciation) in the Mytilus galloprovincialis, as well by using metallothioneins (MT) concentrations, micronuclei (MN) in gill cells and biological parameters (condition index and gonadosomatic index). Concentrations of MT were in the range from 44 to 175 %g g%1 wet matter tissue and were higher at the end of the winter season. The frequency of MN did not indicate an elevated level. Sewage sludge pollution was not confirmed. Elevated As concentrations in mussel are related to salinity and low nutrients concentrations and not to pollution. Elevated concentrations of Cu, Zn and Pb were found in the Bay of Koper in comparison with the Bays of Strunjan and Piran.

Fish are an important part of a balanced diet. V Slovenia there is scarce data and no systematically done analysis of nutritional quality of commonly available and commonly consumed fish. Therefore, different species of fish, available on Slovenian market were collected and analysed for proximate and fatty acid composition. Fish originated from freshwater and marine fish farms, or were caught in their wild environment. Both freshwater and marine fish were either of Slovenian origin (wild and farmed) or fish were farmed or caught in other countries (abroad). Proximate and fatty acid composition (FAC) of fish, farmed or caught in Slovenia, did not differ from the proximate and FAC of the matching fish species of foreign origin. There were no significant differences in nutritional quality (EPA and DHA content) between analysed freshwater and marine fish species.

Cultured and wild sea bass are good sources of protein and n-3 LC PUFA. fatty acids. FA composition can be used for differentiation between wild and cultured sae bass due to differences in proportion of n-6 PUFA. Results from our study indicate that there is no difference in nutritional quality (content of n-3 LC PUFA) between cultured and wild sea bass.

To compare the sensorial quality of wild and farmed brown trout 34 consumer were asked to decide which of the two samples presented to them in double blind test was preferred regarding appearance, aroma, juiciness, mouth feeling and general impression if difference in mentioned traits between both samples was detected. Results showed that for all traits at least 75% of consumers stated that they noticed difference. For appearance and aroma wild trout was preferred, for juiciness and mouth feeling farmed trout was favored. General impression of wild brown trout was favored by 15 consumers, while 16 consumers regarding this trait preferred farmed brown trout. Meaning and importance of results from consumers' panel test for positioning of products from fish farming and fisherz is discussed.
