These juvenile Chinook salmon are referred to as "Parr", for the drippy colorations that run vertically along their sides. Parr marks" provide protective coloration helping them avoid predators while rearing in freshwater. As these young fish continue to mature, they eventually take on a silvery coloration and are referred to as smolts. At this stage of development they begin to make the physiological changes that will allow them to transition from freshwater to saltwater as they migrate through the hydro system to the ocean.
