Lorraine Loomis: What we don’t know about of harbor seals and California sea lions could be hurting salmon, orcas

What we don’t know about populations of harbor seals and California sea lions in western Washington could be hurting salmon, orcas and other marine species — as well as fishing communities and economies — far more than we think. It’s estimated that seals and sea lions eat about 1.4 million pounds annually of threatened Puget Sound chinook and take six times more salmon than Indian and non-Indian fisheries combined. Historically, tribal fishermen never used to see seals and sea lions traveling up western Washington rivers. Today, we need to manage in-river predation by harbor seals of out-migrating juvenile salmon and returning adults — especially the threatened chinook that are their favorite target. >click to read< 10:17
