Discussion
- 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)
Facts
- 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)
