How about above ground repro tanks? Cheaper, quicker, easily seined/drained.
1000G stock tank.
Fabricate spawning habitat for FHM - easy
GSH - I've heard yarn on bottom or furnace filters work
PK - bales of hay according to Lusk suffice as forage - not sure about spawning? Any ideas?
Tarp to cover the tanks to discourage predators and provide shade. Suspend a few inches from top of tank.
Need release on bottom of tank so you're not spilling fry over the edges - screen the out flow to prevent major loss of fry.
Aquamax pellet and fry powder for the GSH and FHM - hay bales for the PK.
