Özet:

 Objective: In this study, various characteristics of the Eğirdir minnow, an endemic species of Anatolia that inhabits specificnarrow areas, were determined from 142 individuals sampled between 2021 and 2022. These characteristics include length-weight relationship, Von Bertalanffy growth equation, condition factors, spawning season, first spawning size, and fecundity attributes. Materials and Methods: A monthly sampling of 142 specimens of Egirdira nigra was conducted using multi-mesh gill nets between March 2021 and April 2022. Results: The sampled E. nigra population consists of individuals aged II-V, with 57.75 female and 42.25 male. The length-weight relationships were as follows: W  0.0059 L3.5445, R²  0.9312 female  male, W  0.009 L3.3077, R²  0.9353 male, and W  0.0058 L3.5679, R²  0.9233 female. The condition factors were calculated as 1.67 male and 1.87 female. The gonadosomatic index was highest in March 13.95 and lowest in August 0.5073. The populations mean fecundity was calculated as 4787 individualsegg. Conclusion: Although the population exhibits a wide age range and positive growth values, it is believed to be under significant threat from invasiveexotic species sharing the same environment, such as Atherina boyeri, Gambusia holbrooki, Pseudorasbora parva, and Carassius gibelio. Therefore, the conservation of species and their habitats is of paramount importance.
