Salmonid smolting: a pre-adaptation to the oceanic environment

  • Chapter
Fish Ecophysiology

Part of the book series: Chapman & Hall Fish and Fisheries Series ((FIFI,volume 9))

Abstract

Salmonids are a small family of fishes characterized by high morphological and behavioural homogeneity. These characteristics make it possible, for example, to produce many interspecific hybrids, some of them fertile. However, there is one specific aspect where a clear difference appears, allowing separation of the family into two groups, one remaining in fresh water, the other migrating to the sea. Although at present, no salmonid species is totally marine, and some species remain in fresh water for their entire life. others achieve an active migration from fresh water (FW) to the estuary, and finally to the sea. Later they return to fresh water for spawning.
