This study was conducted in Dardanelles between October 2007 and August 2009 when condition index, meat yield, biochemical com- positions and environmental parameters of seawater were investigated and the study area was found to have available conditions for cul- tivation. Investigation of the study area showed a positive correlation in particular among condition index, seasonal variation of temperature, protein, fat and chlorophyll-a; a negative correlation was seen between them and carbohydrate value. It was clear from the two years study that the most ideal period for oyster harvest is April and August especially when condition index was maximum followed by a winter with no oyster yield is available in terms of the related processes involving oyster cultivation. ©Copyright H.
