Thanks that was very useful. And when I said perch i was referring to yellow perch as i don't think white perch would be a good idea? When i say i can catch all the fish in the pond, i mean it. There are a few catfish and bass, but the rest are hybrid bluegill which don't spawn much at all. The pond does have a release valve for drainage but i don't think it'll be necessary. The ponds were poorly stocked to begin with, but they will work. Do you have any ideas about how walleye get along with smb/lmb? And also if i can setup the perfect spawning habitats for walleye to spawn, what are my odds of success ( again this is just curiosity because i have a few ponds to experiment with) Do you also have experience with white sucker and rock bass? they seem like good forage for walleye or smb. I am just thinking about what i could do to manage my ponds
