Özet

This paper studies age, growth and hatch date distributions of young of the year striped sea bream Lithognathus mormyrus from Canakkale near shores by using a beach seine during September 2006-December 2007. Using otolith microstructure analysis, a total of 416 specimens ranging from 20 to 103mm L-T were aged and found to be between 30 and 307 days old. Average growth rates were estimated to 0.325mmd(-1). The juvenile instantaneous mortality coefficient was found to be 0.0219, which corresponds to a daily mortality of 2.16%. The hatching period of the striped sea bream was determined to occur between April and January, with relatively higher hatching frequency in August.
