FAIRBANKS -- State Fish and Game Department officials say the first pulse of king salmon heading up the Yukon River is expected anytime.

Subsistence fishing has been closed for District Y-1 until further notice because of special restrictions placed on this year's salmon harvest.

Subsistence fishing in districts Y-2 and Y-3 will be closed as the first pulse of salmon heads upstream.

A below-average to poor harvest is expected this year, and officials say the limits on subsistence fishing are needed to ensure enough fish reach Canada to meet treaty agreements.
