Özet
Spat recruitment of a large bivalve species endemic to the Mediterranean Sea and naturally found at Izmir, Turkey (Urla, Karantina Island), the fan mussel Pinna nobilis (Linnaeus, 1758), has been researched. The study was carried out between May and October 2012. The aim of this study was to determine the spat recruitment of the fan mussel. Collector systems were prepared with onion bags and pvc pipes. Collectors were deployed at two different depths (1 m and 8 m). Every month a new collector system was deployed at the study site and previous collectors were recovered. Length and weight of attached spats were recorded. Water temperature, salinity, chlorophyll-a and particulate matter were measured monthly. Surface collectors gathered 60.6 % of total spats. It was observed that, June, July and August were the most appropriate months to deploy fan mussel spat collectors for this site. Our results also showed that the main recruitment period of Pinna nobilis spat at the study site was between July and September.
