Abstract EN

A total of 410 Tilapia zillii, 70 Clarias gariepinus, 30 Bagrus bajad and 15 Chrysichthys auratus fishes were collected from different water bodies in Qua-lyobia Governorate.

Microscopic examination of samples showed infection in muscles and head region (gills & branchial cavity) with encysted metacercariae in 91.7% of T.

zillii, 82.85% of CI.

Gariepinus, 70% of B.

bajad and 86.66% of Ch.

auratus.

The highest distribution of metacercarial infection among the T.

zillii was in The muscles of posterior third and tail followed by the middle third, anterior Third and head region (gills & branchial cavity) while the highest distribution of .

Metacercarial infection among CI.

Gariepinus was in the middle third muscles followed by the posterior third, anterior third and lastly in the head region.

The highest metacercarial infection among B.

bajad and Ch.

auratus fish was in the posterior third muscles and branchial cavity respectively.

The taxonomic morphology of the encysted metacercariae and the excysted ones was given
