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 conservation of habitats and cross multiple international borders which make conservation acts even harder to organize and manage. Their habitat must be fixed and monitored before we can even begin to think about conserving and protecting these magnificent creatures. Salmon are a very resilient species, but human causes are driving them to the brink of disaster as we continue to invade their habitat space. Dams, population growth and other human causes are significantly impacting salmon runs and the way that these organisms live. The life cycle of salmon is a very important factor in conservation. They return to the same gravel
