Growth and survival rates of different size classes of black mussel (Mytilus galloprovincialis Lamarck, 1819) at two culture systems in Dardanelles

This study was conducted in Kilya Bay, Dardanelles between May 2002 - May 2003. Growth rate of different size groups of mussels (10 +/- 2, 20 +/- 2, 30 +/- 2, 40 +/- 2, 50 +/- 2, 60 +/- 2, 70 +/- 2 mm) in rope system were shown higher than net system. Significantly relation was found amoung growth rate of mussel water temperature and chlorophyll-a (p<0.05). Growth rate of two system decreased from small size groups to bigger size groups. Survival rate of mussels in net system were found better than rope system (p<0.05). Survival rate of bigger size groups were determined higher than small size groups in both system (p<0.05).
