The death toll at an Okanogan County aqua-farm likely will hit 5,000 fish, due to massive water spills over Grand Coulee Dam.
Ed Shallenberger, vice president of Columbia River Fish Farm, predicted last week he'd lose 3,000 of the steelhead he raises to sell to restaurants.
But divers had pulled 4,771 dead fish from the farm's net pens by the end of the day Thursday. Fewer carcasses are found each day, Shallenberger said, and few of the 170,000 surviving fish show signs of gas bubble trauma.
