Introduction
In Recirculatory Aquaculture System (RAS), the water is recycled and resused, after the removal of waste materials. It is mainly used for high-density culture of various fish species. This technology will improve income and encourage small-scale farmers and women to take up fish culture in their household backyards.
The technological know-how, needed for this project will be provided by the National Centre for Aquatic Animal Health (NCAAH) and Cochin University of Science and Technology (CUSAT), Kerala.
Most suitable fish species for backyard culture with RAS technology are Monosex, Tilapia, and Pangasius.
Assisstance for the project
The experts from NCAAH will help the farmers in setting up of fish tank, getting water testing kits, cages, pumps, aerators, filters etc. There is also a provision for subsidy under RAS technology:
