(Portland, OR) -- A bounty program that pays to catch salmon-killing Northern Pikeminnow paid out one-point-three million dollars this year. Over 140-thousand of the fish were caught by nearly 12-hundred anglers in the Columbia and Snake rivers. The bounty pays 6 to 10 dollars per fish, with tagged fish worth 200 to 500 dollars. The top fisherman caught nearly seven-thousand fish and earned 69-thousand dollars. Northern Pikeminnow are not native to the Northwest. They prey on young salmon and they're removed to help increase the salmon population.
