Ovarian nematode (Nematoda: Philometra sp.) infestation on Pseudorhombus triocellatus (Paralichthydiadae)

This is the first report of Philometra sp. in the ovary of Pseudorhombus triocellatus. On the basis of nematode infestation may cause serious damage to ovary by slurping the blood, causing atrophy of developing ova, fibrosis, increasing granulocytes and hemorrhages, thus harmfully affect the fish reproduction and indirectly affect the fisher men communities.
