Flat oyster (Ostrea edulis, Linnaeus 1758) are distribution on all sea coasts of Turkey. The flat
oyster is an oyster species of economic importance and high nutritional value. Only fisheries of
flat oyster is done in Turkey. This study was conducted in the Çanakkale Strait (Çardak Lagoon)
between November 2017 and August 2018. Meat yield, condition index and biochemical
composition (protein, lipid, carbohydrate, moisture and ash) of flat oyster samples collected
monthly were investigated. The lengths of the samples ranged from 78.13 mm to 86.58 mm,
and their weights ranged from 74.85 g to 108.06 g. According to AFNOR index, flat oysters
distributed in the Çanakkale Strait are of “fine” quality in July and “speciale” quality in other
months. When the biochemical composition of flat oysters was examined, it was determined
that the amount of protein and lipid was high and the amount of carbohydrates was low in the
spring. While a positive correlation was observed between the length, weight and amount of
carbohydrate of the flat oyster, a negative correlation was observed between the amount of
protein (p>0.05). Differences were found between months in the protein, lipid and carbohydrate
values of flat oyster (p<0.05). The difference between months in the biochemical composition
of the flat oyster may be due to factors such as reproduction, temperature and food.
Consequently, in terms of AFNOR index and biochemical composition, it is thought that flat
oysters in this region are suitable for consumption throughout the year and this region can be
evaluated for aquaculture.
