Salmon run plankton. At this point the baby salmon are called "fry". At the end of the summer the fry develop into juvenile fish called "parr". Parr feed on small invertebrates and are camouflaged with a pattern of spots and vertical bars. They remain in this stage for up to three years. As they approach the time when they are ready to migrate out to the sea the parr lose their camouflage bars and undergo a process of physiological changes which allows them to survive the shift from freshwater to saltwater. At this point salmon are called "smolt". Smolt spend time in
Salmon River (New York) will enter the river. Fishing activity on the Salmon River once again peaks during this spring spawning season. Both brown trout and steelhead are capable of spawning multiple times during their lifespan, and many "drop back" to Lake Ontario after spawning; these fish are aggressive feeders and popular targets of anglers. The stocking of so-called summer-run steelhead (skamania) aims to increase summer trout fishing opportunities on the Salmon River, as these fish tend to enter the river as early as June. Although river-running salmon and trout cannot migrate beyond the Lighthouse Hill Dam, the reservoirs and river stretches beyond the
