Abstract

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.
