Species profiles: life histories and environmental requirements of coastal fishes and invertebrates (Pacific Northwest)<>9d\pink salmon

Oncorhynchus gorbuscha, the most abundant of the Pacific salmon species, spawn in North American and Asian streams bordering the Pacific and Arctic Oceans. They have a very simple 2yr life cycle. Adults spawn in the fall and the young fry emerge in the spring. The Puget Sound region of Washington State is the southern geographic limit of streams supporting major pink salmon runs in the E North Pacific. Pink salmon runs are presently only in odd-numbers years in this region. Optimum water temperatures for spawning range from 7.2-12.8°C. Productive pink salmon streams have <5% by volume of fine sediments (≤0.8mm). -from Authors
