Fig 3How many fish can you put in a 700-gallon tank? How much food do you give them? How much food is too much food? How much fish that you can grow in a pond in a year?

To answer these questions, New Alchemy researchers began a scientific quest to understand the production potential and ecological limits of small-scale aquaculture. The effort of learning enough to make this computer simulation simultaneously resulted in learning enough to maximize practical fish production.
