World’s hardest



            fighting fish


              saved from



                extinction




          Called “Tiger of Water” for its fighting prowess,
       Mahaseer, which is considered as the world’s hardest
       fighting fish has been saved from brink of extinction
      through a conservation plan launched in the reservoirs
      and rivers of the hill state of Himachal Pradesh. Efforts
         to conserve this species of fish are commendable
      because their future is under serious threat as rivers are
      getting polluted and dams built over rivers to tap hydro
        power generation, have blocked water for these fish
              species to grow, writes charanjit ahuja
