ABSTRACT Rotifers are the connecting link between primary producers and consumers of higher orders in aquatic food web. Yedshi lake is a rural lake in Mangrulpir Tahsil, Dist. Washim of Maharashtra and has less human interference . Quantitative and qualitative analysis of rotifer community was done on monthly basis from October 2006 to September 2007 by collecting water samples from five different spots of the lake. During the study period total 25 rotifer species belonging to 14 genera were identified. The Brachionus was recorded as the most diversified genera represented by five species . The seasonal rotifer biodiversity study showed the peak in density and diversity during summer season while lower values were observed in rainy season. Key Words : Yedshi Lake. rotifer biodiversity, seasonal variations. DIVERSITY OF SOME BLUE GREEN ALGAE FROM JAYAKWADI BIRD SANCTUARY, PAITHAN, MAHARASHTRA J.AQUA.BIOL., 24 (2), 2009 : 5 – 11.

E-mail : Prakash Papdiwal ABSTRACT Diversity of blue green algae in the Jayakwadi Bird Sanctuary has been studied for four years (2005-2008) and their taxonomic accounts have been given. Among the blue green algae, genera of Arthrospira, Spirulina, Oscillatoria, Lyngbya and Anabeana were observed at the locations Bramhgavan, Dhakephal, Kaigaon and Nathsagar North; during September to March. A detailed systematic account of these 5 genera and 32 species is given in the present communication, as a first phase of ecological studies of the Sanctuary. Key words: Cyanophyceae, Algal diversity, Jayakwadi Bird Sanctuary CORRELATION BETWEEN WATER QUALITY PARAMETERS ANDPHYTOPLANKTON OF BICHERLI POND, BEAWAR, RAJASTHAN AQUA.BIOL., VOL. 22(2), 2007 : 13 - 20.

ABSTRACT Present study was undertaken to investigate the physico-chemical characteristics and phytoplankton composition of the Bicherli pond, Beawar. Physico-chemical analysis of lake water exhibited high values of nitrate which favoured the growth of phytoplankton. Dominance of Cyanophyceae in summer and Bacillariophyceae in monsoon revealed distinct seasonal variation in the distribution of phytoplankton. The pond was found to be polluted and showed a trend of increasing eutrophication. Keywords: Physico-chemical characteristics, Phytoplankton,Correlation.

College, Bairagarh, Bhopal, Madhya Pradesh. ABSTRACT The phytoplankton of Wular Lake was sampled from five stations from March 2002 to February 2004. All together 24 water samples were analysed with main emphasis on phytoplankton. A total of 100 species of phytoplankton were enumerated with Bacillariophyceae contributed 42 species, Chlorophyceae 43 species, Cyanophyceae 10 species, Euglenophyceae 3 species while, Dinophyceae and Chrysophyceae contributed 1 species each. The very high Nitrate and Phosphate concentration in the lake is the indication of pollution. Diversity values vary from (- 0.66) – ( -0.53) site1, ( -0.59) - ( -0.27) site2 , (- 0.57) – (-0.39) site3, ( -0.56) – (-0.46), site4, ( - 0.45) – (-0.34) site5. Statistically positive correlation was found between phytoplankton counts and dissolved oxygen. While nitrate and phosphate showed the negative correlation (NO3-N -0.34) and (PO4 –P = - 0.49). The shanon’s index indicates that the Wular Lake is eutrophic in nature. Key words: phytoplankton eutrophication Wular Lake: STUDIES ON ROTIFER FAUNA IN FRESH WATER WETLANDS (AMBONA LAKE IN YEOTMAL DISTRICT OF MAHARASHTRA J.Aqua.Biol., Vol 23 (2), 2008 : 8 - 10.

College Washim (M.S.) ** Former Director of Higher Education, Govt. of Maharashtra, Pune, Maharashtra. ABSTRACT Several authors contributed to the study of Rotifer in India (Dhanapati, 2000). However, studies on rotifer fauna from Maharashtra State are scanty (Malu, 2000; Mukhopadhya et al.,1981 and Patil 1978). Present paper describes eight species of rotifers from Ambona lake near Umarkhed, district Yeotmal, Maharashtra. The lake lies in nearly circular depression surrounding two sides by a steeply escarpment. Seven species of rotifers belonging to two genera viz., Brachionus and Keretella belonging to the family Brachionidae were recorded during the study. The study further revealed that Brachionus was the dominant genus and Brachionus calciflorus as numerically abundant species. Occurrence of Bravhionus is definite indication of Eutrophic status of the lake water. Taxonomic notes and a key for their identification are appended and there bioindicator value in the aquatic pollution studies is discussed. Key Words : Ambona Lake, Rotifer fauna.

ABSTRACT Zooplankton occupy an important position in the trophic structure and play the major role in the energy transfer in an aquatic ecosystem .An inadequate knowledge of zooplankton biodiversity is a major handicap for better understanding of life processes of fresh waterbodies.Zooplankton survey of Rishi lake of Karanja Lad and Yedshi lake of Yedshi village, District Washim ,Maharashtra was carried out from June 2005 to May 2006. In Rishi lake , out of 70 species identified ,34 species (48.57%) were represented by Rotifera, 10 species (14.08%) by Protozoa ,10 (14.08%)by Copepoda, 09 (12.85 %) by Cladocera and 07(10.00 %) by Ostracoda while in Yedshi lake zooplankton population was represented by 45 species which included 27 species (60.00 %) of Rotifera, 02 species (4.44%)of Protozoa, 08 species (17.77 %) of Cladocera, 05 species (11.11%) of Copepoda and 03 species (06.66%) of Ostracoda. Rotifer dominated both the waterbodies throughout the study period .Zooplankton biodiversity of Rishi lake was found dominant over the Yedshi lake.

Rajan,M.K., Mahendran, M., Pavaraj, M and S.Muniasamy, Post-graduate and Research Department of Zoology, Ayya Nadar Janaki Ammal College (Autonomous), Sivakasi – 626 214 (West) Tamilnadu. ABSTRACT A survey on zooplankton diversity of three selected polluted water bodies from Virudhunagar district, Tamilnadu was undertaken during three different seasons viz., Pre-monsoon (Aug 2005) Monsoon (Nov. 2005) and Post monsoon (Jan. 2006) to evaluate the impact of water pollution and season on zooplankton diversity. The study revealed the occurrence of seven species of Copepoda, seven species of Rotifera, five species of Cladocera and three species of Ostracoda in these habitats. Among the zooplankton population, the species of Copepoda and Rotifera were found to be dominant throughout the period of investigation. The zooplankton population shows higher density during post-monsoon and the lower during the pre-monsoon season. Key Words : Diversity, Bio-indicator, Environmental Impact Assessment (EIA). PHYTOPLANKTON DIVERSITY OF FOUR LENTIC WATER BODIES IN AND AROUND DAVANGARERE CITY, KARNATAKA J.AQUA.BIOL., VOL. 21(2), 2006 : 13 - 18. Nafeesa Begum and J. Narayana Department of P.G Studies and Research in Environmental Sciences, Kuvempu University, Jnana Sahyadri, Shimoga – 577 451, Karnataka. ABSTRACT Four Lentic water bodies in and around Davangere city were selected for the study. Water samples were collected and analysed to investigate physico-chemical characteristics and phytoplankton diversity were studied from October-2003 to September-2004. Considerable seasonal variations were noted in water temperature, pH, DO, Total alkalinity, Magnesium, Sulphate, Phosphate and Nitrate. In Hadadikere high BOD values were recorded during summer season. Total Hardness is more during winter season. In Bathikere high values of Sulphate is recorded during rainy season. TV-Station Reservoir represents lower concentration of physicochemical characteristics when compared to other water bodies. The five groups of phytoplankton comprise Chlorococcales, Diatoms, Blue-greens, Desmids and Euglenoids were recorded and seasonal variations of these groups are represented. The results of phytoplankton diversity reveals that Chlorococcales shows dominated in TV- Station Reservoir and Yelebeturkere. Similarly
