My wife and I went cat fishing in one of our favourite remote rivers,( in one of our never let you down holes), that drain into the east side of Lake Winnipeg. Never caught a cat in the three days there. Instead we caught 1 Crappie, 60+ Rock Bass, 17 Walleye, 1 Perch and four of these guys. All of the fish were caught on circle hooks size 4/0 and 6/0 and shrimp and worms. We didn't take tackle for anything other than channel cats. What a surprise!
