In this study, the length at first maturity and growth characteristics of big scale sand smelt (Atherina boyeri Risso 1810) were investigated in İznik Lake. Catching trials conducted on a monthly basis 4 different stations lake between March 2014 February 2015 beach seine net with 6 mm codend mesh size was used samplings. The overall sex ratio subsample founded as 1:1.46 (F:M; 1180 females, 1729 males). fork range 3.3-11.2 cm for females 2.9-9.7 males. equations found TW=0.005FL3.160 TW=0.006FL3.067 female male respectively. Allometric (+) has been shown both groups. According to logistic regression model results, (L50) estimated 4.62 4.25 While properties species similarity other habitats populations, values some differences.
