Popis: | Differences in gonadal development and time of spawning were found in two coexisting morphotypes of Arctic charr Salvelinus alpinus in Kalandsvatnet, Norway. Spawning depth and some main life-history variables also differed. These observations suggest that the two morphotypes do not interbreed freely. |
