Pond Boss Forums STOCKING A NEW POND Raising Forage and Bait Pen raising fish

Canyon for your blocking net Rainman has it correct - 1/4". Most pond water quality conditions will cause the net to quickly become clogged with algae growth. IMO the big disadvantage to a blocking net is the fish are trapped in shallow water and very vulnerable to heron predation. Depending on how many FHM you want to raise, I would use a net pen (cage). Spawning devices could be created using layers of some type of sheeting that is layered to allow the adults to get in between the layer to lay and guard their eggs. Then remove the sheets and hatch them in an aerated tub or similar container. When eggs have hatched and fry are swimming, dump it into a grow out pond.
