Population structure of Killifish, Aphanius anatoliae (Cyprinodontidae) endemic to Anatolia in Lake Eğirdir-Isparta (Turkey)

 The population structure of Aphanius anatoliae in Lake Eğirdir-Isparta-Turkey was studied, using ۵۲۲ fish monthly in ۲۰۰۸. 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 by examination of the content of the digestive track. Males made up ۵۱.۹۲%, and females ۴۸.۰۸% of the population. The length-weight relationship and Von Bertalanffy growth equation were estimated as W= ۰.۰۲۳۲ e ۰.۰۹۸L, r=۰.۸۲۶۲, Lt = ۵۴.۵۱ (۱ – e –۰.۲۷۹ ( t+۱.۳۴۵)), respectively. Bacillariophyta, Gammarus pulex and aquatic insecta are the major food items for Aphanius anatoliae.
