The main advantage [...]

An open system provides the easiest and least technology demanding way to grow fish. In [...]

Semi closed systems are similar to open systems in that they use water from a lake or pond, but that is where the similarities end. In a semi closed system the pond or lake is taken out of the equation and the water is pumped into a man made facility. The facility will choose how [...]
