Random biological activities in relation to physico-chemical parameter of shallow water in catchment area of Bhopal’s upper lake

Abstract

Freshwater resources are considered to be the wealth of Nation. Urbanization, agricultural and uncontrolled anthropogenic activities leads to the nutrient accumulation, silt and sediment deposition, and addition of organic matter in the lake from the catchment area in the aquatic ecosystems causing their deterioration and caused them to lose their importance. As the biological activities of lakes or any water body is largely depending upon its water quality in varied aspects, thus, present investigation is aimed at instantaneous existence of interdependent physico-chemical hydrological quality to various life forms of Bhopal’s upper lake to understand the level pollution due to anthropogenic regions. Temperature, pH, transparency, total hardness, nitrates, phosphates, biological oxygen demand were measured for water samples collected from four sites, Boat club, Koh-e-Fiza, Karbala and Bairagarh region designated as S-1, S-2, S-3 and S-4 respectively. Occurrence of aquatic plants Eichhornia crassipes, Pistia stratiotes, Ceratophyllum demersum, Eleodea Canadensis and Azolla spp.; algal species Anabaena sp., Microcystis aeroginosa, Oscillatoria tenuis and Chlorella spp.;ornamental fishes Trichogaster lalius, Trichogaster fasciata, and Badis badis; and snails were noticed at random in relation to the current physico-chemical conditions of water that were supporting the flourishing of such biological forms in the sites. Upon further studies, these biological forms could be explored in socio-economic development of some communities that rely aquaculture based economy.
