for North Island lake by Colton for walleys over 18 inches. The usual mercury and no more than 7 ounces per week for a healthy adult, women who plam to become pregnant no more than 7 ounces per month and kids 4 ounces per month. Don't know if anyone fishes there but now you know. They might have made it for walleyes so far but I wouledn't be to happy about eating other fish either. If it's in walleys it should be in everything else.
