Pond culture

• Water mass is maintained by artificially erected dikes.
• Usually filled by rainfall, canal, or spring water.
• May be extensive, intensive, semi-intensive, mono, or polyculture.

Cage culture

• Defined as raising fish from the juvenile stage to commercial size in a volume of water enclosed on all sides including the bottom.
• Readily adapted to water areas that can’t be drained or otherwise harvested.
• The stocking density of 10 fingerlings/m³ is recommended.
• The average weight of fingerlings stocked varies from 15-25 g.
• Has the following advantages:

1. Economic use of natural water resources that are unsuitable for other means of fish culture.
2. Removal of organic matter and nutrients accumulated in plankton as fish flesh.
3. Low investment but high return.
4. Easy prevention and control of fish disease and predators.
5. Easy harvest at desirable quantity within the stock, and time.
6. In times of emergencies, cages can be removed from one place to another.
