These aerialists of the trout family are spectacular fighters and give a strong battle to fishermen. DESCRIPTION Rainbow trout are easily identified by the broad reddish band or "rainbow" which runs along the side of the fish from head to tail. The reddish band blends ii a dark olive green on the back and pure white or silvery on the belly. The back, dorsal fin, and tail are generously sprinkled with black spots. The brightness of color varies with where the fish lives and what it eats. Rj bow sometimes migrate to the ocean where they spend several years of their life. Whenthey return to their stream to spawn they have acquired a grayish tinge from the salt water and are called steelhead. HABITAT The rainbow is a native of the Pacific slope of the Sierras from California to Alaska. It has since been transplanted to nearly every state in the Union. Trout prefer clear, cool, un- polluted water and are usually not found in waters without these qualities. LIFE HISTORY Wild rainbows usually spawn in the spring during their second or third year of life. The female deposits the eggs in the gravel of the streambed. The size of the female determines the number of eggs produced. In 8 weeks or more, depending on water temperature, the eggs hatch. The growth rate of the newly hatched fish varies and depends on such factors as water temperature, food supply, and water chemistry. From the many eggs deposited in the gravel, only a few young fish survive to adulthood. Therefore, relatively few trout reach catchable size to be taken by fishermen.
