Özet

The population structure of Aphanius mento in Ki{dotless}rkgöz Spring (37°06′ 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. © Central Fisheries Research Institute (CFRI) Trabzon, Turkey and Japan International Cooperation Agency (JICA).
