Abstract

The karyotype of Atyaephyra desmarestii, the European freshwater shrimp, from Louros River (NW Greece) was studied through the examination of metaphase chromosome spreads from the first zoeal stage larval tissues. A total of 42 mitotic metaphases were examined and the diploid chromosome number was determined to 2n = 32. The karyotype consisted of 22 metacentric and 10 submetacentric chromosomes. Atyaephyra desmarestii karyotype is reported here for the first time providing a basis for further cytogenetic comparative study of the species populations.
