Is there any problem with using chain link fencing that could be shaped into a cylinder (tubular) formation, with the open ends facing up and down, and staked into the pond bottom with a metal post? Or how about green vinyl covered chain link fence? Or, that orange or green plastic snow fencing? Would chicken wire also do the job, or would the algae and other plants clog up the spaces too quickly? I know Bill Cody suggested the smaller the holes in the material the better. I just might be checking out a few barns and some other places for these materials and was thinking of using them if available. I would think the minnows and fry could go in and out of these materials for needed protection, while also developing a place for bass to hang out to cast a line towards. Thoughts? Cons?
