I have three small wet weather ponds (soil won't hold water completely but ponds are always 1/4 to completely full year 
round) and am wondering what types of aquaculture systems could be installed in them. One is rectangular, 
25'X35'X5'deepX33Kgallons, the other two are oblong, one 5-6' deep X maybe 10-12Kgallons, the other 4-5' in small deep 
area X 15-17Kgallons. We have had 4 successive periods of high rainfall over the past two months and these ponds are 
full almost to overflowing. Runoff from 3 acres of gardens is their primary source of water.

What are possibilities for growing food fish in these? I am in plant 
hardiness zone 7a.

I can overwinter duckweed, cattails, papyrus, water lillies, several aquarium 
plants
(the kind with long branching single stems with whorls of small oblong leaves that is a rapid grower and can clog a 
small fish pool) and probably many other plants. Unfortunately water hyacinths are not hardy here but can be 
overwintered in a protected container for relocation to the ponds in warm weather. Water hyacinths, cattails and 
duckweed will turn murky water crystal clear in a few weeks in warm weather. It would seem that there ought to be a
few food fish varieties that I could grow. What about clams, crawfish, shrimp?

Any ideas and pointers to online resources and publications would be 
appreciated.
