Sciaenid fishes (croakers), Argyrosomus regius, Pseudotolithus (Fonticulus) elongatus and Pseudotolithus (Pseudotolithus) senegalensis were isolated from fish samples collected monthly from November 2004 to June 2006 at flood tide in Buguma creek, Niger Delta, Nigeria. The fish samples were caught by the use of hooks and lines and cast nets. A total of seven hundred and eighty nine specimens comprising A. regius (12), P. (Fonticulus) elongatus (753) and P. (Pseudotolithus) senegalensis (24) were examined for gastrointestinal helminth parasites. All helminth parasites observed were nematodes. No infection was recorded in A. regius. P. (Pseudotolithus) senegalensis had the highest prevalence (41.7%), followed by P. (Fonticulus) elongatus (23.4%). A total of 57 helminth parasites were recorded, of which 54 were found in P. (Fonticulus) elongtus, and 20 in P. (Pseudololithus) senegalensis. Goezia sigalasi (Ascarididae) and Pseudanisakis sp. (Heterocheilidae) had the highest prevalence in both species of sciaenid fishes infected.
