| Summary: | This study covered some aspects of the biology and control
of monogenetic trematode from walking cat fish Clarias batrachus
(L innaeus ) .
The monogenetic trematode from walking catfish at
Wirya Mina Fish Farm , Depok , Bogor, Indonesia was identified
as Quadriacanthus kobiensis Ha Ky, 1968.Three levels of infection with Q . kobiensis were
established in C . batrachus to study its effect on growth rate .
The mean number o f parasite for the three treatments were: l ow
12.2, medium 12.8 and high 187.3 . Results of the effect of this parasite on walking cat fish Clarias batrachus showed
that the specific growth rate at all levels of infection: l ow ,
medium and high were significantly lower than the control .
This parasite can reduce the specific growth rate of walking
cat fish by 52 . 9% as compared to the control . There was no
significant difference of the specific growth rates amongst
fish with high , medium and low levels of infection . No
significant difference was seen in the mortality rate at these
levels of infection when compared with the control . |
