Absolutely. What you do is raise them for feeding. They would not last minutes in ponds I have. However, I do have one pond where I could get them in there before LMB hatch. But the best plkan is to raise them in tanks and keep feeding them, a self sustained colony, and then supplement feed them in an aquarium or pond. I dobt they would last long enough in any pond with small fish to be effective vs. Algae.
