§Based on importance values helminth species were classified into categories; Dominant (D), species strongly characteristic of the community (I > 1.0), Codominant (CO-D) species contributing significantly to the community (0.01 < I < 1.0), Subordinate species occurring infrequently, they do not contribute significantly to the community (0 < I < 0.01).
