| Abstract: |
The Monogenetic parasite identified as Dactylogyrus extensus (Mueller & van Cleave, 1932), and
Dactylogyrus vastator Nybelin, 1924 has been found parasitized to fries and fingerlings of common carp
cultured in Godawary and Trishuli Fisheries Research Station. On the basis of earlier history on
Dactylogyrus, it is proposed that D. extensus and D. vastator are new occurrence in Nepal.
T.he proportion of mean prevalence of Dactylogyrus infection to common carp fingerlings was significantly
dtfferent (P<0.05) in all season (winter, summer and rainy season) at Godawari Station. Likewise in Trishuli
Station also found significantly different (P<0.05) in summer and rainy season but no parasite was observed
i~ winter. The mean intensity rate of parasitic trend per infected common carp fingerlings was significantly
dt!ferent (P<0.05) in summer and rainy season at Trishuli Station but not significantly different (P>0.05) in
wmter, summer and rainy season at Godawari Station. |
