Unidentified Gastro-Intestinal Nematode Parasites from Pseudotolithus elongatus, Rivers State, Nigeria

Pseudotolithus elongatus specimens (n=50) purchased from fishers at Nembe waterside, Port Harcourt, Nigeria, in May-June, 2018, were examined for gastro-intestinal parasites using standard procedures. The fish species were identified using taxonomical keys. Nematode parasites isolated were fixed in 70% ethanol. Photomicrographs of the parasites were taken using Nikon digital camera attached to the objective lens of a compound microscope after clearing in lactophenol. Nematodes and a didymozoid trematode were isolated from infected specimens. These could not be identified using available taxonomical keys and are hereby presented in this short communication
