ABSTRACT

 

Uttarakhand, a newly created hill state of India, is enriched with aquatic ecosystem of various disciplines like rivers, streams, lakes and reservoirs. The important rivers are Alaknanda, Bhagirathi, Bhilangana, Mandakini, Koshi, Ganga and Yamuna. The rivers are snow fed and spring fed. There are large number of snow fed rivers and streams such as Alaknanda, Bhagirathi, Mandakini and Ganga. Besides the snow fed rivers, there are so many spring fed rivers such as Henwal, HemGanga, Song, Suswa, Ganga and hundreds of rivulets. They all contain a very rich and colourful fish fauna. River Hemwal, Hem Ganga, Song and Suswa are tributaries of river Ganga. In the present study some spring fed and snow fed rivers such as Henwal, HemGanga, Ganga, Song, Suswa, Alaknanda, Bhagirathi and Bhilangana were investigated. During the course of study a total of 53 species belonging to 11 families were reported out of these 52 species were reported in Ganga 38 in Henwal, 36 in HemGanga, 48 in Song, 44 in river Suswa 32 in Alaknanda, 32 in Bhagirathi and 29 in river Bhilangana. Besides the collection of fishes the physico-chemical parameters such as temperature, velocity, turbidity, conductivity, total dissolved solids, pH, alkalinity, free CO2, DO, BOD, chlorides, calcium and magnesium were also analyzed. Some endangered and rare fish fauna are also reported in the present investigation.
