The Pacific ocean is filled with fish. Big fish, little fish. Fish that eat other fish. Fish that get eaten by humans. None of these fish are more important to British Columbia, Canada1 than the Pacific salmon.
Apart from their economic value, salmon are of enormous cultural significance to the indigenous people of the Pacific coast. This has led to conflict between indigenous groups, representatives of the commercial and sport fisheries, and logging interests.
Salmon are born in streams up to 700 miles from the sea. After growing and developing in the streams, the salmon make their way to the ocean. After some time in the ocean2, the salmon return, lay eggs, and die.
There are five major species of Pacific salmon.
- Colour: Blue-tinged silver

- Weight: 7 pounds
- Also known as: 'Bluebacks' (Columbia river) or 'Reds' (Alaska)
Sockeye spawn in streams that have lakes nearby. Young sockeye do not survive unless they spend between one and three years in a lake. Spawning males have large humped backs and sharply hooked jaws.

Pinks only spend six months in fresh water. When going to spawn, male salmon develop large humped backs. They are rather scary looking.
