Hi, Sylvia,

Thank you for your email. I took that photo on a pond in a park nearby (Schlitz Audubon Nature center, Bayside, Wisconsin) [http://www.schlitzauduboncenter.com/] where I volunteer from time to time. I never practice Aquaponic gardening but am interested to know more about it. I visited Growing Powers in Milwaukee where they have a very sophisticated system of raising Tilapias with an "river" of cress to purify the water in the fish tank. I was also impressed by their way of heating their green houses by putting a pile of a certain mixture (I forgot what is was, but it was producing enough heat to avoid freezing) on the corner of the green house. I have a 36 x 48 ft fenced garden, but the nearby trees are growing so much than there is less and less sun, so my wife took over most of it to grow flowers to attract birds and butterflies. She loves animals and we have plenty of wild life around here, despite the fact that we are in town. (squirrels, of course, chipmunks, coyotes, raccoons, deer, etc).

For the garden, I am using the square foot gardening method and it works beautifully, but seasons are short here.
With my best wishes,

Jean-Pierre
