Özet

This study was carried out to determine the relationships between physicochemical parameters and morphometric and reproduction features of the crayfishes (Astacus leptodactylus) in Yenice Central Irrigation Pond. Results of MDS analysis revealed that the relationships between physicochemical parameters and morphometric features and reproduction features in crayfishes could be explained at different rates. Reproduction features such as fecundity and sperm production, were within a close relationship with temperature, magnesium, conductivity, dissolved oxygen, and the abdomen weight, carapace weight, abdominal width, carapace width, abdomen length, carapace length from morphometric features were within a close relationship especially with dissolved oxygen, magnesium, calcium, and temperature. These relationships could play an important role while considering the selection of maternal females for cultural environments and for the management of productive population, and for the selection of water sources that can be effective for populations that is generated by vaccination.
