More than 6000 granite quarries existing the foot hills of Western Ghats, the longest mountain range of Southern India. These perennial fresh water reservoirs are optimum for initiating fish culture whereas normal farming methods are not viable due to the depth ranging from 10 to 60 meters that would make harvesting practically impossible. With a view to utilize these resources, a cage fish culture model was demonstrated in partnership with a traditional farmer. Small floating cages made using HDPE nets and PVC pipes were erected in the quarry. Locally preferred fish species Pearl spot, Tilapia and Pangasius were cultured in cages.

Output of the intervention: Average production from one cage was 130 to 150 Kg and the farmer received a net income of INR 14,300/-. One cent area can accommodate 7 such cages. The demonstration realized the practical viability of the model as an income generating source from the otherwise abandoned granite quarries.

 Outcome of the intervention: Based on the successful demonstration of KVK’s high density cage fin fish farming model in granite quarries, the Fish Farmers Development Agency (FFDA) under the State Government has launched a subsidy scheme to further popularize this technology. Under this scheme entitled Cage fish culture in abandoned water bodies the agency supported cage fish farming in granite quarries. Total 50 cage units, each comprising 2 cages received financial assistance (INR8000/- per cage unit)  from the agency during 2015-16 year. KVK was the technology partner in this programme.
