Recirculatory Aquaculture System (RAS) is a technology where water is recycled and reused after mechanical and biological filtration and removal of suspended matter and metabolites. This method is used for high-density culture of various species of fish, utilizing minimum land area and water.

Component of Mini RAS

  • Tarpaulin tank with a capacity of 15000 L

  • Aquaponic unit

  • Filtration unit

  • Pump  

  • Aerator

  • Solar panel with battery 

  • PVC pipes & connectors

Set-Up Requirement

  • Land of approx. 300 sq. ft.

  • Good water source

  • Source of fish seed and feed

Advantages of Mini-RAS

  • Small, easily fit in small spaces or backyards & terraces, portable easy to shift & fit

  • Reduction of direct operational costs associated with feed, predator control, and parasites

  • Risk reduction due to climatic factors, disease, and parasite impacts

  • RAS production can promote flexibility in terms of farming location and proximity to the market

  • Enable production of a broad range of species irrespective of temperature requirements

  • Reduced exposure to weather, unfavorable temperature conditions, external pollution, and predation

  • Judicial use of water and land areas

  • Opportunity to integrate with backyard
