Cage Culture

Cage culture is an aquaculture production system where fish are held in floating net pens. These cages are used to culture several types of shellfish and finfish species in fresh, brackish and marine waters.

Cage culture of fish utilizes existing water resources but encloses the fish in a cage or basket which allows water to pass freely between the fish and the pond permitting water exchange and waste removal into the surrounding water.

Cages are used to culture several types of shellfish and finfish species in fresh, brackish and marine waters. Cages in freshwaters are used for food fish culture and for fry to fingerling rearing.

Its installation is easy.

flexibility of management.

effective use of fish feeds.

less manpower requirement.

better control of the fish population.

In emergencies it can be removed from one place to another.

Treatment of disease is much simple than that of pond culture.

It requires less investment because it uses existing water bodies, and simple technology and swift return of investment.

controlling the unwanted reproduction of tilapia, therefore mixed-sex populations can be reared in cages.

close observation and sampling of fish are simple and therefore only minimal supervision is needed.

many types of water resources can be used, including lakes, reservoirs, ponds, and rivers.

fish handling and harvesting are very simple and help to maintain the non-seasonal supply of the fish.

Since the cage has meshed, fish inside has fewer chances of being attacked by predators.

They can be used to clean up eutrophicated waters through a culture of caged planktivorous species such as silver carp.

Cage culture has advantages which include:

Many types of water resources can be used, including lakes, reservoirs, ponds, strip pits, streams and rivers which could otherwise not be harvested.

A relatively low initial investment is required in an existing body of water.

Harvesting is simplified.

Observation and sampling of fish are simplified.

It allows the use of the pond for sport fishing or the culture of other species.

Less manpower requirement.

Generation of job opportunities for unemployed youth and women.

Additional income to fishers during closed seasons.
