As a part of study of feasibility of Aquaponics system in Indian contest, we have started trials on RAS system in Vigyan ashram. In this trail we want to study scope and feasibility of high density fish farming in drought prone conditions like Pabal. In earlier trials of aquaponics,  maintaining required fish density and water quality parameters  were important challenge. By setting RAS we wish to overcome these challenges and converted  stystem further aquaponics farming. Please follow following link for details —
