“…Many workers have worked on systematics of parasites, biology of fish, ecology of parasites and histopathology of tissues infected by parasites (Ramadevi and Rao, 1974;Kanth and Srivastava, 1987;Koul et al, 1991;Chowdhary, 1992;Sinha et al, 2008;Wani and Magray, 2008;Pardeshi and Hiware, 2011;Chandra et al, 2011;Gupta et al, 2012;Verma and Capoor, 2013). However, very few investigations on parasite community structure of freshwater fishes was conducted worldwide by Sirikanchana (1983), Nahar et al (1993), Parween and Rahman (2000), Poulin (2001), Chaiyapo et al (2007), Chandra (2008), Alam et al (2010), Bhuiyan (2011), Rakibuzzaman et al (2011), Ayaz et al (2013), Miah et al (2013) and Bhuiyan et al, (2014). These types of ecological studies are scarce in Indian Sub-continent especially in Andhra Pradesh.…”
