Abstract:
A study on identification of Clinostomum infections in Trichogaster trichopterus in
Pekanbaru has been conducted on August to October 2011. This study aims to understand the
topography of Clinostomum in Trichogaster trichopterus. Excysted Clinostomum sp. was found in
cavity organ were aseptically taken using needle, preserved in absolute ethanol. Morphological
examination was done with Scanning Electron Microscopy (SEM). Result shown that topography of
the tegument of Clinostomum sp. metacercariae infections in Trichogaster trichopterus in Pekanbaru
indicated different structure in individual surface. Oral sucker located at the subterminal end, ellips
and was surrounded by fine surface pucker. The ventral sucker was close to oral sucker toward
anterior area, and had round sensory papillae without spinae. The body surface was concave without
spinae and was completed with round papillae. Round and pucker-surrounded excretory pore
appeared at the posterior terminal. Results of Scanning Electron Microscopy indicates that
Clinostomum sp. identified in this study was similar to Clinostomum cutaneum.
