While, eggs then hatch from December to February, depending on water temperature and the juveniles emerge from the gravel during March and April. Furthermore, develop a large kype during spawning. Generally, the female lays from 1000 to 2000 eggs in several clutches within the nest, which can be fertilized by different males. We will be sending you also our bi-weekly newsletter for free when you subscribe. Meanwhile, at this stage, they are very sensitive to aquatic and sedimental contaminants. We now are seeing greater numbers of fish, as well as bigger and bigger fish each year. While, size is correlated to elevation and productivity of the stream. Furthermore, the back is brownish or olive. Spawn in moderately large, clear, well-oxygenated shallow rivers with gravel substrates. Therefore, less popular with sport anglers than other salmon species. Therefore, recovering depressed populations by restoring habitat and removing non-native species. Meanwhile, more aggressive reintroduction of the Greenback into the wild has been occurring since 2014. Changing to a piscivorous diet of small fish entering their adulthood. A yellowish gold color with a golden belly and medium-sized dark spots that are evenly spaced and that may extend below the lateral line onto the dorsal and tail fins.
