Background on Fisheries Development in Karnataka

  • National Fisheries Development Board (NFDB), has sanctioned 500 brackish-water cages to Central Marine Fisheries Research Institute (CMFRI) for installation in selected District of Karnataka.

  • Cage-based farming in floating cages, in reservoirs is new to state. Compared to other type of fish farming, this is cost-effective & increases inland fish production substantially.

  • At KRS, department w/Central govt. ‘s 3 cr. assistance erected floating cages 5 × 4x6 metres & released 5,000 fingerlings. Department took up Pangasius variety. This variety is yet to gain acceptance. It is ready for harvest & expect to get 3,500 – 4,000 kg.
