Keywords:
Abstract
Narmada River, a mighty west flowing river is the fifth largest river in India. At present pollution load of river increases rapidly. Benthic Macro invertebrates are used as pollution indicators that live on or inside the river bed of a water body. Recently this region is rapidly undergoing industrialization, township etc., and such these areas are prone to habitat loss due to which different types of poisonous and non-poisonous snakes are being noticed in the residential areas. Snake bite is an acute life threatening hazard often faced by farm labors and farmers leads to death. This study aims to reduce such problems. The whole Narmada valley of Jabalpur region was selected as study site for the collection of sample. The present study was carried out from January 2014 to December 2016. Sampling of snakes was done as per the requirement of local people. Four study sites had been selected for the investigation of benthos were Bargi dam, Gwarighat, Tilwaraghat and Bhedaghat. Organisms were identified by using standard identification keys provided by Fraser (1933, 1934 and 1936); Mitra (2006); Subramanian (2005, 2009); Andrew et al., (2009); Varshney (1983); Tonapi (1980); Adoni et al., (1985); SubbaRao (1993), Smith (1943); Whitaker & Captain (2004) and indiansnakes.org. In present study total 81 species of various fauna have been recorded viz., Odonata 37 species (7 Families), Lepidoptera 25 Species (5 Families), Mollusca 13 Species (2 Class), Reptiles 06 species (2 families). Benthos helps to assess quality of water and play an important role in food chain for the natural balance. In the same way this study will help people to know venomous snakes when encountered namely, Common Krait, Spectacled Cobra, Russell’s viper and Saw-scaled Viper; responsible for more than 80% fatalities in Indian Subcontinent. The whole study on benthos as well as reptile encircle around environment and human welfare.References
