ABSTRACT Crustaceans are major group of biotic community in both fresh water and marine water aquatic ecosystem. Crustacean species density and diversity correlated with the physico-chemical characteristics of water reveal the trophic status of water body. Study on species diversity of microscopic crustacean were conducted for the year 2011-12 (July 2011 to June 2012) in Karmaveer Kannamwar Reservoir; Regadi, Tehsil Chamorshi, District Gadchiroli, Maharashtra. Samples for analysis were collected monthly in morning hours between 8:00 am to 10:00 am with the help of plankton net made of silk bolting cloth no. 25 (Mesh size 50). Samples were preserved in 4% formalin and qualitative analysis done in the laboratory using binocular light microscope. During the present investigation 13 species were recorded which belongs to 3 major groups of class crustacean of phylum Arthropoda i.e. Copepoda, Cladocera and Ostracoda. Keywords: Crustacean, diversity, K. K. reservoir and Regadi. INTRODUCTION Zooplanktons are free floating minute aquatic organism found both in fresh water as well as in marine water ecosystem. These are one of the important biotic components that influence the food chain, food web and energy transfer in aquatic ecosystem. Zooplankton acts as main sources of nutrient rich food for many planktivorous fishes (Balayla and Moss, 2004, Tijare and Shastrakar, 2012). The freshwater zooplankton comprises protozoa, rotifers, microscopic crustaceans and microinvertibrates suspended in water. The density and diversity of zooplankton correlates with the physico-chemical characteristics of water (Jafari et al., 2011). Zooplankton play important role in biomonitoring of water pollution (Tyor et al., 2014). They are also considered as indicators of water quality (Pinto-Coelho et al., 2005; Rajashekhar et al., 2009; Joshi, 2011). Several other investigators also worked on composition and seasonal dynamics of zooplankton from various fresh waterbadies (Dhembare; 2005, Kamble and Meshram; 2005, Pawar and Pulle; 2005, Kiran; 2007, Tijare and Thosar; 2008, Rajashekar et al. 2009 and National conference on Innovations in Agri-Biosciences (NCIABS-2016) | 165 Meshram et al., 2016 Rajagopal et al, 2010). Crustaceans are one of the group of zooplankton of fresh water aquatic ecosystem plays important role in aquatic food web and also affect primary productivity as their chief food is phytoplankton (Gonzalez, 2000). Cladocerans generally contribute largely to zooplankton biomass and act as a key element in the freshwater food webs (Hessen et al., 2003). Present study conducted to analyze the species diversity of crustacean zooplankton of K.K. reservoir. Study area: Gadchiroli is densely forest covered district and is situated eastern part of Maharashtra. It is poorly irrigated district by dams, large reservoirs but is blessed with some perennial flowing rivers like Wainganga, Godavari, Pranhita, Kathani, Khobragadi, Gadhavi etc. and many ponds and lakes. The present study is conducted in fresh water reservoir named as Karmaveer Kannamwar Reservoir which is situated in Gadchiroli district near the village Regadi, Tah. Chamorshi (Maharashtra). Geographically the reservoir lies between 19°-47’-0” altitude and 80°-7-0” longitude. The Reservoir is surrounded by green forest and hills. It is constructed on Deena River which is one of the tributaries of Pranhita River, so that Karmaveer Kannamwar Reservoir is also known as Deena Project or Deena Dam. This reservoir is primarily used for agricultural irrigation and for fish culture.

Planktonic samples were collected with the help of plankton net made of silk bolting cloth no. 25 (Mesh size 50) and were preserved in 4% formalin. Qualitative analysis of samples were done in the laboratory by using binocular light microscope. Identification of Zooplankton was carried by prescribed keys given by Edmondson (1959) and Battish (1992). RESULT AND DISCUSSION In the present investigations 13 species of crustacean zooplankton were recorded from the three different sites S1, S2 and S3 resp. of Karmaveer Kannamwar reservoir (Dina Dam); Regdi. 13 species belongs to three major groups of crustacean zooplankton; of which 7 species namely Ceriodaphnia sp., Chydorus ovalis , Bosmina longirostris , Bosminopsis deitersi , Moina macrura , Alona monacantha and Diphanosoma sp. belongs to order Cladocera while 5 species i.e. Cyclops sp., Diaptomus nudus, Eucyclops sp., Mesocyclops sp., and Halicyclops sp. belonging to order Copepoda and 1 Cypris sp .belongs to Ostracoda. Study reveals that major dominated group was Cladocera followed by Copepoda and Ostracoda in microcrustacea faunal diversity. Bhat et al., (2015) reported 11 sp of Cladocera, 5 species of Copepoda and 3 species of Ostracoda during ecological investigation of zooplankton abundance in the Bhoj Wetland at Bhopal. Similar results were also observed by Thirupathaiah M. et al., observed 8 species of Cladocera, 6 species of Copepoda and 2 species of Ostracoda in Lower Manair reservoir, Karimnagar, Aandhra Pradesh (India). Similar type of study has been carried out by Tijare, R.V. (2010) from fresh water lake of Gadchiroli city. Narasimha Ramulu K and Benarjee G (2013) revealed the similar result, among crustacean zooplankton 23 species recorded of which Cladoceran species diversity was most abundant followed by Copepods and Ostracods of sub urban perennial water body, located in Nagaram village in Warangal district of Andhra Pradesh; 10 species belongs to Cladocera, 08 species of Copepoda Int.
