| Summary: | Channa micropeltes or toman is a native freshwater fish species and not
commercially species in Malaysia. The fish become one of the anglers’ attractions to Kenyir
Lake, especially for recreational fishing purpose. However, parasitic diseases are one of the
most common problems for this fish population. Studies on parasites of C. micropeltes is
essential to our knowledge for the maintenance of natural resources. So, the objectives of this
study were to identify the cestode and observe the histopathological changes on gastrointestinal
tract of infected C. micropeltes. About 15 C. micropeltes were caught by using fishing rod. The
fish were pithing, dissected and gastrointestinal tract was removed, then placed on petri dish.
The stomach and intestine were fixed in 10% buffered formalin and proceed for preparing
histology slides by using standard method for histology. Then, the tissues were stained by using
hematoxylin and eosin (H & E) stain. The tissue changes were described. The cestodes were
collected, fixed in 70% ethanol, stained with aceto-carmine and prepared the permanent slide.
The cestodes morphology were observed under microscope for identification. In this study,
only Senga rostellarae was identified. The histopathological changes showed the intestine with
severe villus damage with destruction of villi epithelium and necrosis. Some areas with cross
section of cestode showed increase of goblet cells and generated necrosis. Based on this study,
S. rostellarae was a dominant species, and its activities caused severe damage to the fish
intestine. The conditions can cause death to the fish due to hemorrhage and malabsorption of
