Abstract

Some trematode larvae were found in the cranial cavity of Clarias lazera and C. anguillaris. Feeding experiments were carried out on parasite-free pupies and kittens. Samples of stool of these animals were examined from the 3rd day after infection to detect any trema tode ova. When the ova were detcted, the animals were sacrified to obtain the adult flukes which were identified as Diplostomum tregenna NAZMI GOHAR, 1932.
The examination of fish revealed the presence of 6 forms of metacerca riae infesting the muscles of seventeen species of fishes. The met acerca riae of each form were fed singly to the parasite-free puppies and kittons. When the ova appeared in stool, the animals were killed to obtain the adult flukes which were identified as prohamistomum vivax SONSINO, 1892 and Haplorchis yokogawi KATSUTA, 1932.
