Studies on the Pollution of the Kalinadi by Industrial Wastes near Mansurpur Part 2: Biological Index of Pollution and Biological Characteristics of the River
Abstract From the biological data presented here it is difficult to define any species of fish as an indicator of pollution in the strict sense. Nevertheless, the following generalizations are possible. ‐ Species as Wallago attu, Clarias batrachus, Heteropneustes fossilis, Ophiocephalus striatus and...

The whole stretch of heavy pollution is almost devoid of carp and featherback. The following important conclusions can be drawn from the distribution of plankton and bottom organisms: ‐ The higher number of protozoans, chironomids, maggots and the decrease in the number of mollusca can be considered as the indicator of pollution, because of their abundance in polluted zones. ‐ Chlorella, Lyngbya, Gyrosigma and Euglena (algae), Viviparius (mollusc) and Bosmina (crustacea) are very sensitive to pollution. ‐ Oscillatoria, Pandorina, Anabaena, Nitzschia, Closterium (algae), Branchionus, Rotatoria (rotifers) and Naidium (annelid) are moderately sensitive. ‐ Synedra, Spirogyra, Desmidium, Rivularia, Navicula, Fragillaria Phacus, Arcella and Vorticella are fairly tolerant forms. The stretch studied has been subdivided into five zones with characteristic features: ‐ The Oligosaprobic Zone ‐ characterized by a sufficient oxygen saturation, low B. O. D. and C. O.
