What is a Baby Salmon Called?

Baby salmon are called different names depending on the stage after hatching. When they first hatch they are called Alevin. When they are big enough to swim out of the gravel they are called Fry. They are still very small at this point. When they reach about six inches long they are called Parr. Some After one to three years they are ready to swim into the ocean and they are now called Smolt until they reach adulthood.
