In one year period, 276 wild (n=169) and cultured (n=107) yellow-fin seabream fish were
studied for parasitic diseases and associated intestinal lesions in north coasts of Persian Gulf.
Overall, 4 different nematode species of Anisakidae family isolated including Anisakis larvae
(from intestine, abdominal cavity, liver and intestine surface), Contracaecum larvae (from
intestines and abdominal cavity), Raphidascaris spp. (from intestines) and Hysterothylacium
spp. (from intestines). The highest and lowest rate of infection with Contracaecum spp. was seen
in winter and autumn, respectively; and that of Hysterothylacium spp. occurred in winter and
summer, respectively; and with Anisakis spp. such rates were seen in summer and autumn,
respectively. All of seasonal variations in infection rates were significant. A significant positive
correlation was found between weight of fish and parasite burden. This is the first report of
Hysterothylacium spp. in the yellow-fin seabream.
