abstract
The objective of the present study was to apply certain chemical means for reducing chloride salinity levels in aqueous medium. For this purpose, the excess chlorides were controlled through chemical applications using formic acid in the presence of Labeo rohita fingerlings in aquarium environment. The effects of this particular chemical on the water quality as well as on fish survival and growth parameters was also studied. The results indicated that formic acid was not found much effective in reducing chloride salinity levels to appreciable limits, however water quality was not much affected by its usage. The fish growth and survival rates were also found non-satisfactory and higher doses resulted in toxic effects on these parameters. The results of all these efforts concluded that the use of this chemical for chloride salinity reductions should not be recommended.
