I appreciate everyone's input so far, ya'll have cleared up a lot of questions.
-Is there any threat of Moz T surviving the winter and overpopulating? Anyone have experience with a climate similar to
Seguin, TX?-Should I stock snails or crayfish? Is that even possible? It seems they'd be decent forage for RES and BG/LMB when they're first introduced.
-Do the Tiger or F1 hybrids do well in ponds? Should I mix strains in stocking?
I have access to a slightly smaller, older pond on a different property (about 6 miles away) that's usually choked with algae and weeds. I'm thinking about getting a couple pounds of Moz T, dumping them in there once the ponds has had water for a few months, and seeing if they survive winter. The pond might not be a perfect reference: it's smaller and shallower, and also well sheltered by trees and ground contours. It should at least give me a reference for whether there's a real threat of Moz T takeover in an area pond.
