Effective Saturday, fishermen will be allowed to catch only one silver salmon per day. Each fish must be at least 20 inches.
The normal catch limit of two fish per day remains in effect throughout the rest of the Kodiak road system. A fisherman may catch one silver salmon in the Buskin and another in another road system river in the same day.
The restriction comes as silver salmon stack up at the mouth of the Buskin river, waiting for water levels to rise and carry oxygen-rich water from Buskin Lake into Buskin River.
According to measurements taken by the department of fish and game, bacteria consuming rotting pink salmon in the river are consuming oxygen to the point that the river cannot support migrating silver salmon.
So far this year, the counting weir on the Buskin River has recorded 506 fish. The silver salmon escapement goal for the year is between 3,200 and 7,200 fish.
Donn Tracy, sportfish management biologist for Kodiak, said the reduced catch limit may be adjusted if the river level rises and fish return in numbers sufficient to reach the escapement goal.
