Participants in the Kenai River personal-use dipnet fishery will be prohibited from retaining king salmon when the fishery opens Tuesday. The Alaska Department of Fish and Game issued an emergency order Friday prohibiting the retention of king salmon due to below average numbers of kings in the river. According to a Fish and Game news release accompanying the emergency order, based on low abundance of king salmon in Cook Inlet and in other parts of the state, it is likely that the late run of Kenai River king salmon also will be well below average and require conservative management by Fish and Game. According to the emergency order, any king salmon caught in a dipnet may not be removed from the water and must be released immediately unharmed. The Kenai River personal-use dipnet fishery runs through July 31.
