  • Spawning is initiated at temperature 4-7C (ref: QuigIgoe2004)
  • Landlocked populations and large parts of anadromous populations usually reproduce only once in their life. Juveniles prefer fresh or brackish water until they mature. (ref: redlist)


  • Bas Kooijman: O. mordax and O. eperlanus are here treated as sufficiently similar in view of the large effect of varying environmental conditions (temp, salinity, food)
