¹ Süleyman Demirel University, Fisheries Faculty, 32500 Eğirdir, Isparta, Türkiye Viewed : 4159 - Downloaded : 3565 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, L_t = 23.51 (1 – e ^{–0.041 (t+2.904)}) and W_t = 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. Keywords : Kırkgöz Spring (Antalya), Aphanius mento, Growth, Diet
