The reproduction of Aphanius mento is described from the Kırkgöz Spring (Turkey) (37º06' N; 30°35' E) between
January 2002 and December 2002. In this study, the sex ratio, age, the relationship between fecundity and fish length, weight
and gonad weight, the gonadosomatic index, egg diameter and the first age of maturation were observed. Age range was
determined as 0-VII years for 654 individuals. The overall male to female ratio was 1.10 : 1.00. Spawning period was between
May and July. The first maturation was found to be at age I. First maturity length (Lm) was estimated at 2.45 cm for females.
The mean fecundity per individual was found to be 228.48±28.60. The mean egg diameter was calculated as 1,240.09±53.26
μm.
