Bill Cody, you quoted from Wetzel that certain taxa of algae exhibit higher ability to survive and even bloom in cold conditions and even under ice. If these algae strains don't go absolutely wild in warmer conditions and take over a pond, they might be valuable to innoculate a pond with right at the time of fall overturn. Their increased numbers could possibly provide a 'low tech' oxygenation of the iced over pond, again, providing they wouldn't take over in the warmer months. Do you have more specific species names for these alga? It would be interesting to read up on their requirements. It would be very cool to be able to buy a culture of algae to innoculate a pond with to insure oxygen saturation sans electricity.
