Gamogenetic cycle, the condition index and meat yield of the Arca noae Linnaeus, 1758 (Noah's ark shell) were followed in Gerence Bay (Aegean Sea, Turkey), between August 2009 and July 2010. Temperature, salinity, chlorophyll-a, particulate organic and inorganic matter were monitored during the sampling period. According to histological observation, inactive stage was determined as 100% in September. The spawning period was observed through the year except September, with a peak from April to June. Sex ratios were not equal and females were dominant during the study period (2: 1). Meat yield, condition index and gonad index reveal a positive relationship between each other (P=0.05). Among environmental parameters, inverse relationship was only found between particulate inorganic matter and reproduction (P=0.05).
