High school students are fish farming after school, working with a school of approximately 130 iridescent tilapia in two large black tanks in a greenhouse.
At the end of the day, the finger length fish are tended by students, in an ecological haven behind the high school which includes the greenhouse and a student garden. The fish are not pets; they will some day be the main course at school lunch assuming all goes well and they survive the winter.
The two tanks are designed as an aquaponics system that allows water to flow from one take into several rows of basil plants, where the fish waste is deposited as fertilizer, and then empties into the second tank.
There is also a composting system behind the school. It was developed as an independent study and Eagle Scout project by 17 year old Chris Carlson. The intent is to heat the fish tanks during the winter and promote healthy growth of the fish so they can be eaten.
The compost material from the school cafeteria is held in a stack of hay bales, topped with leaf litter from the village. Plastic piping circles through the pile, which will carry water to the fish tanks, heated by the warming of the decomposing compost.
