Extensive fish farming system
The extensive fish farming system is the least managed form of fish farming, in which little
care is taken. This system involves large ponds measuring 1 to 5 ha in area with stocking density
limited to only less than 5000 fishes/ha. No supplemental feeding or fertilisation is provided. Fish
depends only on natural foods. Yield is poor (500 to 2 ton/ha), and survival is low. The labour and
