Design & Construction Of Cage Culture System In Fisheries Faculty, BSMRAU.
What is Cage Culture?
Fish can be cultured in one of four culture systems: ponds, raceways, recirculating systems or cages. A cage or net pen is a system that confines the fish or shellfish in a mesh enclosure.
Why cage culture?
Stocking with the right fish species, using seed of appropriate size and introducing it at the right time are essential to optimizing fish yield from reservoirs.
Cage culture is suitable to a wide range of open freshwater ecosystems, especially reservoirs.
It uses simple technology and locally available resources for cage construction and operation, making it economically, socially and environmentally sound.
Obviously, It is a huge source to income money.
