Sažetak
Oysters, including the Pacific oyster Magallana gigas, are popular aquaculture species and are therefore moved and introduced worldwide. The Pacific oyster is native to the northwest Pacific Ocean and is the most agressive invader of all oyster species. It was first introduced to Europe (France) in the 1960s for aquaculture. Its first record in the Croatian region of the Adriatic Sea was in 1972 in Istria (Lim Bay), where it was intentionally introduced to determine its potential as an aquaculture species and from where it is presumed to have spread to form wild colonies. So far, wild Pacific oyster colonies are restricted to the northern part of the Adriatic Sea along the Istrian Peninsula, where only a few colonies have been recorded (Budava Bay, Lim Bay). In June 2017, two colonies of oysters were found in a bay near Medulin, Istria. Some individuals had an unusual morphology and could not be identified to species from their shells, but were suspected to be Pacific oysters. A small piece of mantle edge tissue was excised from each specimen, preserved in 96% ethanol and stored at 4°C for molecular analysis. After total genomic DNA isolation, the species- specific mitochondrial gene cytochrome c oxidase I gene (COI) was analysed for each sample. Results showed that colonies were mixed, including both Pacific oysters and native European flat oyster Ostrea edulis, Linnaeus 1758. All specimens identified as Pacific oysters had valves with an unusual toothed shape. In the intertidal zone the Pacific oysters were located above the native oysters. These findings are additional proof that invasive Pacific oysters are spreading across the northern Adriatic region and that they should be monitored as a potential threat to native European flat oysters, because they are competing for food with them and are also feeding on native oyster larvae.
