dc.description.abstractThe present study was carried out to determine gonadal stages and quality of pearl oyster meat (Pinctada imbricata radiata, Leach, 1814) in Izmir Bay (Turkey). Pearl oyster samples were collected from the study area at a depth of similar to 5 m between February 2013 and January 2014. The highest and lowest temperature was measured in July and January as 27 degrees C and 14.2 degrees C, respectively. The maximum chlorophyll a value of 4.640 mu g l(-1) was calculated in May and the lowest value of 1.009 mu g l(-1) was recorded in April. Individuals reached their first maturity in April. Spawning activity was observed from June to September and the gonad index (GI) was at the highest level during those months. The development was observed from April to February. The overall female to male ratio was 1.32:1 (p < 0.05) and it did not affect the GI (p > 0.05). There is a strong positive correlation between the GI and temperature (p < 0.05). The highest condition index (CI) was recorded in May as 12.31 +/- 0.51, whereas the lowest one in January as 7.37 +/- 0.22. As a result, this study revealed that the pearl oyster population in the region is characterized by high reproductive activity, especially during the summer months.en_US
