Abstract
The present study deals with the fish diversity of Masyam Khola Palpa, Nepal covering
two seasons winter and spring season using cast net. A total of 255 fish individuals
belonging to 9 species, 7 genera and 2 families was found during study period.
Cyprinidae (n=243) was the dominant family comprising of 7 species among 9 recorded
species. Barilius bendelensis was the most common fish species on the basis of total
no. of catch during the study period followed by Opsarius barna, Puntius sophore and
Garra rupecula. Shannon-Weiner diversity index was highest (1.64) at station II and
station III while lowest (1.44) at station I, simpson index was highest at station II (0.79)
and lowest at station IV (0.76) and evenness index was highest in station I (0.89) and
lowest in station IV (0.76). The environmental variables like DO, pH, temperature, and
velocity were found to be in suitable range for fish habitat.
