Fish cages in Phewa Lake (Nepal)

Cage culture in Phewa lake was started in 1972 with the technical assistance from Japanese Volunteers to protect the common carp broods when water level in the fish ponds in the Fisheries Research Center dropped. In the present, fish species cultured in these cages are grass, silver and bighead carps. Cage management includes the continuous removal of fouling, application of grasses to feed grass carp and maintenance of cage netting. Cage productivity is about 7 kg/m3 of cage water. No artificial feed is provided.
