Besides those Coregoninae
in europe that are mostly spread in lakes there are some species that are
real migratory fishes which are shown in this section.
The Coregoninae of our rivers are diadromous (growing uo in sea and
spawning in the freshwater) migratory fishes.
Migrations mainly take place when swimming to sea as half grownup junveniles
and when swimming upwards the river for spawning. Contrary to the salmon
their migrations are quite shorter because even as grown-ups the stay in
coastal waters and their swimming performance is much less powerful than the
one of Salmons is.
