Would a 2" mesh cage restrain a 1-3" bluegill? (Or RES). I use 1/2" mesh on the main cages, and 1/4" on the fry cages.
As I mentioned earlier, I am seriously contemplating adding HBG into another one of our ponds. This project would be more in line with the "traditional" application of HBG, that being a fun to fish and easy to catch setting. No trophy aspirations here, just raise the fish to a pound or so, harvest as we see fit, and re-stock as necessary. What this situation allows us to do, is utilize slightly bigger stockers initially. Since max growth is not a concern, I don't need to source smaller fish and get them on the program asap in order to maximize potential.
Purchasing 4-5" HBG is a little more expensive than buying 2" fish, but they are better suited to immediate turn-out into the pond, or at least won't need to spend much time in the cage before doing so. And they should still hit that 1 lb mark easily and quickly.
