AB  - The age, growth and reproductive properties of sand smelt, <I>Atherina boyeri</I> Risso 1810, caught from Lake Iznik (Northwest Turkey) were studied by sampling carried out between March 2000 and February 2001. A total of 922 specimens were examined. The age of this species varied from 0-IV and they were composed of 43.6% females, 25.3% males and 31.1% unidentified. The mean total length and weight of the individuals ranged from 12.6-98.2 mm and 0.02-6.89 g, respectively. The Von Bertalanffy Growth Parameters (VBGP) of the population were: L<SUB>&infin;</SUB> = 141.11 mm, K = 0.27 year<SUP>-1</SUP>, t<SUB>o</SUB>= -0.49 years for all individuals. Length-weight relationships were estimated as W = 0.002 TL<SUP>3.485</SUP> for females and W = 0.004 TL<SUP>3.062</SUP> for males. The sex ratio of males to females was 1:1.7. The spawning period recorded from March to July, with a peak in May. The diameter of ripe eggs ranged from 0.60-1.10 mm. Fecundity was calculated as 450 (1st age group) to 1724 (4th age group) eggs/females.
