in alaskan rivers in the spring and summer we get the annual spawning of five different species of salmon. Kings are the biggest and are also called Chinook Salmon. They arrive, spawn and die first. usually followed by Red, silver, pink and chum salmon. By the time the silver salmon or coho hit the rivers from the open ocean the kings are dying on the river banks spent. It's quite a life lesson as you watch and try to catch these river beats of current!!
