This study was conducted to determine the composition, abundance & prevalence of<br />

nematode parasites from purple-spotted bigeye Priacanthus tayenus. Fifteen P.<br />

tayenus samples was acquired from three different fish markets in Sabah (Sandakan,<br />

Kota Kinabalu and Kudat) and immediately preserved in 37% formalin. A total of 76<br />

nematodes that were collected in its well preserved state; with two identified genera:<br />

(1) Hysterothylacium sp. with 49 individual specimens, prevalence of 73% and mean<br />

intensity 4.5; and site infection includes the pyloric caeca, stomach, swim bladder and<br />

body cavity; (2) Anisakis sp. with 27 individual specimens, prevalence of 60%, mean<br />

intensity 3; and site infection includes the pyloric caeca, stomach, body cavity and<br />

liver. This is the first study to retrieve Hysterothylacium sp. and Anisakis sp.<br />

parasitizing preserved Priacanthus tayenus from Sabah waters. Although some<br />

nematodes are known to be zoonotic, this study shows the low count is safe for<br />

consumption<br />
