The population structure of Aphanius mento in Kırkgöz Spring (37º06' N; 30°35' E) was studied, using 654 fish
monthly in 2002. This study were observed in the number of individuals of each sex, age, weight and size compositions. In
addition, the total length-weight relationship was calculated as well as the Von Bertalanffy growth equation. A study of the
food uptake throughout the year has been carried out by examination of the content of the digestive track. Males made up
52.29%, females 47.71% of the population. The length-weight relationship and Von Bertalanffy growth equation were
W=0.0626 L 2.3348, Lt = 23.51 (1 – e –0.041 (t+2.904)) and Wt = 786.25 (1 – e –0.002 (t+0.200))2.3348, respectively. Gammarus sp. and
Palaemon sp. are the major food items for A. mento.
