Lots of people are doing this as a sustainable living model called aquaponics. Raising fast, edible fish in a large several hundred gallon stock tanks, etc like tilapia, perch, etc, then using the water from there to grow vegetables, herbs, etc and other edible plants, thus creating a self sustaining system that you can eat fish and veggies from. Fish breed, you get more fish, save/plant seeds from veggies, repeat, so maybe use your model to explain this to your class.
