SALMON IS A FISH SPECIES THAT LIVES ITS LIFE IN BOTH SEA AND RIVER. THE FRY ARE BORN IN THE RIVERS AND USUALLY SPEND THEIR FIRST YEARS IN THE STREAM AND THENMIGRATE TO THEIR REARING AREAS IN THE SEA. AFTER A FEW YEARS THE SALMON MIGRATES BACK TO SPAWN IN THE STREAM OR RIVER WHERE IT WAS BORN. SALMON IS DEPENDENT ON FREE MIGRATATION, SINCE THE MIGRATION IS AN IMPORTANT PART OF THE BEHAVIOR.
