  • 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).
  • Integrated farming systems (e.g. livestock-fish, agriculture and fish dual use aquaculture and irrigation ponds).

The production of fish from cages is increasing globally. The technologies are now well developed in Europe, parts of South America (Chile in particular) and China. In SE Asia, cage farming of fish is advancing rapidly, in a wide range of species; the main limitations being the availability and high cost of feeds and shortage of seed. There is already considerable transboundary movement of fish seed and fingerlings in Asia, mainly for live fish markets in Hong Kong and China. Little is known of environmental impacts, although this trade is known to result in some destructive fishing techniques for fish fingerlings.
Each country has its own species, markets and issues that need to be addressed in the development of cage culture, but future expansion of this farming system is expected.
