Atlantic salmon are one of the few fish that lives in both fresh water and salt water during its lifetime. Emerging from eggs as alevins they begin their life in the gravel banks of freshwater streams. They are called fry when they leave the gravel and begin foraging for food. The salmon then develop into parr and continue to eat and grow in preparation for their long journey. When they become smolt, they travel from their streams, down river, into the ocean. After a few years in the ocean they return as adults to their home streams to spawn and produce the next generation of salmon.
