Sockeye Salmon
(Yva Momatiuk & John Eastcott / Minden Pictures)
Name: Pacific salmon (Oncorhynchus).
Life: Is born in a stream or lake, then swims to and roams the ocean.
Death: Returns to fresh water to spawn and die.
After Life: Salmon have long been recognized as a major food source for animals and aquatic plants in the fish’s spawning grounds. But researchers at Simon Fraser University have found that nutrients from dead fish influence the number and types of plants that grow more than 100 feet into the forest. The researchers say conservation plans should take into account not only the number of fish needed for a strong population at sea, but also the number that die inland.
