Behavior

Atlantic salmon undergo dramatic life changes, from freshwater juveniles (parr) to ocean-going smolts, then to adult fish that return to spawn. They navigate using a combination of magnetic fields, sun position, and chemical cues from their home river.

Reproduction

Females dig nests called redds in gravel riverbeds where they deposit eggs. Males compete for the right to fertilize eggs. Unlike Pacific salmon, Atlantic salmon can survive spawning and may return to spawn multiple times.
