The ever changing stocking plan of my one acre pond now includes adding HSB next spring. Last fall I put in 250 HBG and the same of RES along with 5 lbs fatheads. This spring I'm adding another 5 lbs fatheads and another 250 HBG. I've got pallets staked all around for the fatheads to breed on--if it ever warms up--and I do plan on feeding. This fall I've ordered 50 walleyes. The plan is to skip LMB and add 50 HSB next spring. Since the pond is new, I thought this would be the perfect opportunity to experiment, and I've always loved wipers. However, I also know of their proclivity to escape. My pond is fed by runoff and has some flow through it. What do I need to do to keep my fish--especially the wipers in. Obviously, it will take some type of screen at the overflow, but I'm looking for ideas as to what specifically to use and how to design it. Thanks.
