This study reports on the parasite composition and load of bigeye scad Selar
crumenopthalmus. Twenty six fish samples were collected from fish markets in Sabah
and preserved in 37% formalin. The methodology used for specimen identification
required the use of a compound microscope and image capturing using Dino eyes and
Scanning Electron Microscope (SEM) to help achieve the first objective. The second
objective was to determine the prevalence and mean intensity of parasites in S.
crumenophthalmus. The identification of the parasites identified two taxa from families
Anisakidae and Cymothoidea. The nematode Anisakis sp. had the highest parasites
prevalence (65.217%) and mean intensity (7.467) and mainly infected stomach as
compared to the crustacean cymothoid Norileca indica, which had lower prevalence
(8.70%) and mean intensity (1) and infected only gills. Cymothoids are non-zoonotic
as compared to most nematodes, in particular Anisaki sp., but the considerably low
infection rate makes it safe for human consumption.
