These factors are continuously impacted by the forest industry and losses of prime salmon habitat is attributed to negative forest practices. Logging can not be accomplished without roadways to the valuable timber. I will examine the impact of forestry's logging roads on the soil and salmon. Salmon Life Cycle Pacific salmon are cold water fish that thrive best in waters no warmer than 70 degrees Fahrenheit or 21 degrees Celsius. Chum and pink salmon migrate almost immediately upon emergence to the ocean.
Sockeye spend the first year or two in a lake system before migrating out to sea.
The cycle begins when a female adult salmon begins site selection and redd construction. After thoroughly cleaning and probing the egg pocket, the female salmon will spawn with a dominant male. The pair deposits fertilized eggs into the clean gravel substrate. Developing eggs and embryos Upon gamete release, eggs water harden immediately and settle into the clean nest. Eggs in the redd will begin to develop upon fertilization.
