Abstract
In this study, we evaluated the parameters of the length-weight relationship and the relative condition factor of endemic Pseudophoxinus antalyae and introduced fish species, Carassius gibelio and Cyprinus carpio in the Kırkgöz Spring-Duden Stream basin. A total of 269 fish were captured from three different sites of the basin from May to September 2022. There were differences in mean length and weight were observed between populations from sites 1 to 3 for three fish species. Negative allometric growth was observed in site 2 population of P. antalyae, whilst site 1 and 3 showed positive allometric growth, and the condition factor (K) for only site 1 was above 1. The populations of C. carpio from sites 2 and 3 showed positive allometric growth, while C. giebelio was negative allometry. K >1 for C. carpio at site 3 and for C. gibelio at site 2. This study can inform both fisheries biology and environmental management for the development and conservation of endemic fish stock.
