Kamarudin, Oman (1989) Some Aspects Of The Biology And Control Of Quadriacanthus Kobiensis Ha Ky, 1968 (Monogenea: Dactylogyridae) From Clarias Batrachus (Linnaeus) In Indonesia. Masters thesis, Universiti Pertanian Malaysia.
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 .
