Abstract
In this study, changes of average monthly values of the condition index of Mediterranean mussel M. galloprovincialis were investigated at seven different locations in the area of Bay of Mali Ston, in the period from November 2008 to December 2009, as well as their relationship with the variation of monthly values of ecological parameters (salinity, temperature, total, organic and inorganic particulate matter). Concentrations of organic and inorganic particulate matter had the highest influence on the condition index at all locations, what indicates the importance of food availability, but also its usability that is influenced by the relation between the concentration of organic and inorganic particulate matter. Mean monthly values of meat indices of mussels at all locations showed statistically significant spatial and temporal variations. This fact indicates that it is necessary to investigate variations of the meat quality at number different locations within the same geografical area. That should be the way for the selection of the production locations within the larger farming areas, and for the strategical organization of the production in order to prolong the market supply with the high quality product. A significant statistical difference was recorded by comparison of the mean monthly values of meat indices with the regard to the dept (1 and 4 m) at different locations. The statistically significant differences in the meat quality of the Mediterranean mussel at the same location at different depths determined during our research, represent a significant economical problem. Producers will have harvest size mussels of different market quality at the same location and the same production unit. This shows that there is a need for applying appropriate equipment and production methods.
