Sažetak
The scallop Pecten jacobaeus (Linnaeus 1758) is commercially valuable bivalve present throughout Mediterranean coastal waters. It lives on sand, mud, and gravel bottoms between 3 and 250 m depth and can grow over 200 mm in diameter. Due to the excellent meat quality and high market price its populations is under high harvesting pressure. Novigrad Sea, a Natura 2000 area, is a registered bivalve production zone, where aquaculture has a high priority. Due to its unique ecological and geographical characteristics (unpolluted sea with high inputs of fresh water from the Zrmanja river), the whole Novigrad sea basin is suitable for intensive bivalve production. The aim of this study was to determine possibilities for commercial production of P. jacobaeus in the Novigrad Sea, by monitoring growth parameters and mortality in the farming conditions. The bivalves were marked individually (Hall print tags) and placed at 20 m depth in lanterns in June 2014 and the growth was measured every six months until July 2017.The results showed that P. jacobaeus grew to a commercial size after 18 months. In contrast, the literature data indicate that in North Adriatic natural population of P. jacobaeus reaches commercial size usually at age of three years. According to our growth data and the absence of mortality, we can state that commercial farming of P. jacobaeus in the Novigrad Sea has good potential. However, insufficient amount of available spat in nature and the lack of hatcheries limits the further development of this form of aquaculture.
