Vol. 7 No. 2A, October-December 2012 PLANKTON BIODIVERSITY OF SIDDHESHWAR DAM IN HINGOLI, MAHARASHTRA, INDIA Shaikh Parveen R.* and Bhosle Arjun B. School of Earth Sciences, Swami Ramanand Teerth Marathwada University, Vishnupuri, Nanded Maharashtra (INDIA) Received September 10, 2012 Accepted December 10, 2012 ABSTRACT The present study deals with the survey of phytoplanktonic and zooplanktonic communities from Siddheshwar reservoir of Maharashtra state, India during July 2009 to June 2011. Presently, 24 phytoplankton genera representing various classes viz: Chlorophyceae (7), Bacillariophyceae (6), Zygnematophyceae (4), Cyanophyceae (2), Flagillariophyceae (2), Ulvophyceae (1), Trebouxiphyceae (1) and Euglenoidea (1) were recorded and the Chlorophyceae formed the dominant class. A total ten Zooplankton genera, three belonging to Monogononta, three to Branchiopoda, two to Maxillopoda, two to Ostracoda and one to Ciliatea were recorded. Key Words : Drinking water, Zooplankton, Siddheshwar dam, Phytoplankton, Biodiversity INTRODUCTION Planktons are the groups of microscopic plants and animals which are minute and able to spend their whole life floating in the water is called as planktons. The name plankton was given by Hansen. Plankton has very flexible locomotary organs. They are unable to move rapidly and also unable to determine direction of their movement. However, they are simply drifted with the current of water and cannot move against the direction of flow. Planktons consisting of plant part called as phytoplanktons while planktons which are of animal origin are called as zooplanktons. Planktons occur in all natural water bodies like ponds, rivers, lakes and dams. Because of their short life cycles, plankters respond quickly to environmental chances and hence their standing crop and species composition are more likely to indicate the quality of the water mass in which they are found. They strongly influence certain non biological aspects of water quality (such as pH, colour, taste and odour) and in a very practical sense, they are a part of water quality. Certain taxa often are useful in determining the origin or recent history of a given water mass. Because of their transient nature and often patchy distribution, however, the utility of plankters as *Author for correspondence water quality indicators may be limited. Information on plankton as indicators is interpreted best in conjunction with concurrently collected, physicochemical and other biological data.1 Phytoplankton constitutes the very basic of nutritional cycle of an aquatic ecosystem. They form a bulk of food for zooplankton, fish and other aquatic organisms. The maintenance of a healthy aquatic ecosystem is dependent on the abiotic properties of water and the biological diversity of the ecosystem.2 Phytoplankton functions as the primary producers in the aquatic biotopes. Hence, the quality and quantity of phytoplankton population bear much influence on the production potential of an aquatic ecosystem. Moreover, the role of phytoplankton in regulating the earth’s temperature is worth mentioning.3 Some species flourish in highly eutrophic waters while others are very sensitive to organic and chemical wastes. Some species develop noxious blooms, sometimes creating offensive tastes and odours or anoxic or toxic conditions resulting in animal deaths or human illness. The species assemblage of phytoplankton and zooplankton also may be useful in assessing water quality.4 Although a number of workers5-9 have studied the dynamics of phytoplankton of freshwater 905 Journal of Environmental Research And Development bodies of India. The taxonomy and distribution of zooplankton in different water bodies reported by a number of investigators.10-12 AIMS AND OBJECTIVES The present study gives an account of biodiversity with reference to phytoplankton and zooplankton from surface water body. Study area Siddheshwar dam constructed on Purna River at Siddheshwar village in the Aundha Taluka, Hingoli district of Maharashtra state, India The river Purna, a tributary of Godavari River rises in the hills of Aurangabad district and after a winding course of about 250 miles, it joins Godavari below Purna Railway Junction. Siddheshwar dam serve as an important source of several benefits and facilities to the region of Hingoli, Parbhani and Nanded districts. This has been selected for carrying out the present research work. It is situated at Northern part of Marathwada region of Maharashtra. The location of dam is at 19035’-19040’ N latitude 7605’-770E longitude. MATERIAL AND METHODS Limnological investigations were carried out during July 2009 to June 2011. Plankton’s samples were collected from freshwater using plankton net. Take a drop of well mixed water by slightly shaking on a clean slide place the cover slip on it or with the help of zero point brush take the material and put it on the slide. Now cover it with the cover slip. Adjust the microscope observe under 10X.Now turn the lens towards under high power using oil emmersion object if required. Identifications were made following APHA.13 J. Environ. Res. Develop. Vol. 7 No. 2A, October-December 2012 RESULTS AND DISCUSSION Altogether 24 taxa of phytoplankton were found during the study period(Fig. 1). Out of which seven taxa belong to Chlorophyceae, six to Bacillario-phyceae, four to Zygnematophyceae, two to Cyanophyceae, two to Flagillariophyceae, one to Ulvophyceae, Trebouxiphyceae and Eugleno-idea.(Fig. 2) Chlorophyceae formed the largest group of phytoplankton contributing 29.16 %.The class contributed 16.66 % of total phytoplankton forming the third largest class of phytoplankton. This group was formed the second largest group of phytoplankton with average contribution of 25 % to the total phytoplankton types. The classes contributed same values i.e. 8.33 % of total phytoplankton. Among these groups each group showing average contribution of 4.16 % to the total phytoplankton types. (Fig. 3) Anitha and Singara found phytoplanktons belonging from classes Chlorophyceae, Bacillariophyceae, Cyanophyceae and Euglenophyceae during July 1999 to June 2001 from Lower Manar Dam and Kakatiya canal, Karimnagar, Andhra Pradesh, India.14,15 About 10 taxa of zooplankton were found during the study period. Among all observed zooplanktons these formed the largest group of zooplankton contributing 30 % to the total zooplankton types. The class contributed 20 % of total zooplankton. Among these groups each group showing average contribution of 10 % to the total zooplankton types. Rajalakshmi and Shakila observed zooplankton like Cyclops, Paramecium, Pleurotrocha, Amoeba, Daphnia, Uronema and Keratella from Kendikulam pond at Peravurani, Thanjavur. Also they found some phytoplankton.13 Domain: Eukaryota Kingdom: Protista Division: Chlorophyta Class: Chlorophyceae Order: Oedogoniales Genus: Oedogonium 906 Journal of Environmental Research And Development J.
