Two Letters Re: Ponds, Aquiculture, and Pond Predators
Hey James, I have been pondering (pun intended) bioponics (AKA aquaponics) for a couple of years now. A seminal site, http://www.townsqr.com/snsaqua/index.html, describes bioponics as “A simple and innovative system of food production combining aquaculture and hydroponic growing techniques without expensive equipment” or the use of mineral nutrient salts. Here’s how it works. Water from the fish tank is pumped to grow beds. In addition to crops, the grow beds contain naturally produced bacteria. The bacteria breaks down the fish waste thus cleaning the water. The plants feed on the nitrogen produced by the bacteria. Finally, the water is …
