Aquaculture Systems and Species

Farming systems are also diverse for example including: Water-based systems (cages and pens inshore/offshore) Land-based systems (rainfed ponds irrigated or flow-through systems tanks and raceways) Recycling systems (high control enclosed systems more open pond based recirculation)
