The sea lions on the Willamette near West Linn don't like the hazing and are forced away when fish and wildlife workers are firing noisemakers over their heads. But as soon as crews go home for the night, the sea lions return to the fish ladders. Tom Murtaugh, a biologist with the State, says they'll need more people next year. The State has just completed year two of a three-year pilot program, designed to find ways to stop the sea lions from feasting on shrinking salmon and steelhead populations.
