                               PRE AND POST IDOL IMMERSION ANALYSIS DATA

                                                                                 PRE                                      POST

                                                                                                                                                                           

• Water Temperature (°C)                              27                                             24                      
• Transparency (cm)                                       15                                             12
• pH                                                                   7.3                                            6.9
• DO₂  (ppm)                                                     7.0                                            6.1
• FCO₂(ppm)                                                     4.0                                          4.4

• Phosphate (ppm)                                         0.050                                        0.060
• Nitrate (ppm)                                              0.41                                          0.52                                      

Conclusion

§Occurrence of blue green algae- microcystis

§Large amount of Rotifers

§Floating vegetation- Eichhornia accompanied by several invertebrates (insects, molluscs)

§Higher dissolved oxygen and high free carbon dioxide

§Slightly alkaline pH

§P/R ratio more than one

   Provide ample evidences of organic pollutant that reflect the nature of pond towards eutrophication process.

     It is a natural process that has been accelerated by human activities and regular influx of sewage.

            Load of organic matter may enhance the growth of microbes that usually degrade the water quality and affect fish production.      

Recommendation

§Dumping of urban wastes and sewage should be properly restricted to retain the quality of pond water.

§Immersion of idol should be avoided to minimize the accumulation of organic and inorganic wastes in the pond.

§Anthropogenic activities like washing of clothes and use of detergent should be discouraged to maintain the quality of water for proper growth of fish.

§Fisheries department should undertake proper management to protect, conserve and propagate fish biota of the pond.

§ Periodical assessment of physico-chemical biological properties are required for a suitable productive pond.

§Periodical renovation of pond will help to restore its productivity and perennial nature.
