Yep - what I like best after several seasons of PITA seining is the gate valve/auto collection effort. It only takes an hour to drain completely, and collecting fish is simple. If one has their forage pond adjacent to the main pond obviously there's zero labor involved other than netting/saving a few adults for brood stock and lifting the gate valve. Then you refill, replace your brood fish, and start again. I would love to have a series of forage/growout ponds around my main pond. If I ever sell my place and start again, this is my plan. Love the auto stocking process...simple and easy.
