In this research, meat yield and shell dimension of smooth scallop (Flexopecten glaber) were specified. 150 individuals of smooth scallop were caught by dredges seasonally in Cardak lagoon on Canakkale strait, Turkey. According to results, the relationship of total shell length between total shell weight was determined as TW = 0.5207* TL 2.4533 (R 2 = 0.73). Moreover, meat yield of scallop was determined highest as whole meat in spring and as adductor muscle in summer. This paper reveals basic growth data of smooth scallop and its preliminary study for Cardak lagoon which is important bivalve inhabiting area.
