The Seattle Times: Local News: Dead zone suspected in fish die-off

A “dead zone” of oxygen-poor water has appeared off the Oregon coast for the fifth year in a row, and reports of crab and fish dying off Washington’s Pacific shore suggest the phenomenon is occurring here, too.

Members of Washington’s Quinault Indian Nation spotted large numbers of dead greenling, rockfish and flatfish on the beach last week. Some live fish were trapped in tide pools, including rat fish — a deep-water species.

“That tells us they were running from something,” said Joe Schumacker, of the tribe’s fisheries department.
