Abstract
The fish diversity of Godavari River at Ambad Stretch (16 km length) was studied by conducting seasonal fish sampling at five identified sampling sites. Fishes were sampled seasonally over a period of two years (2012-2014). The 25 fish species belonging to 10 different families was observed in River Godavari at Ambad Stretch. Among the 10 observed fish families, the fish species belonging to Cyprinidae family was found dominant and shared 29% of total fish population. The Cichlidae was observed as the lowest dominant family contributing only 2.5% to total observed population. The Shannon diversity index was observed between 2.35 and 3.03 among different sampling sites. The maximum Shannon Index of 3.03 was found for undisturbed habitat. The higher degree of the pollution and habitat disturbance made the water quality unsuitable for the growth of the fish community as evidenced from lower diversity index value at polluted site (2.35).
