This study was conducted to determine the food composition and mercury<br />

concentrations in four species of Scombridae family which are Thunnus tonggol,<br />

Rastrelliger kanagurta, Euthynnus affinis and Scomberomorus guttatus collected from<br />

Pulau Kambing landing port at Kuala Terengganu. The mercury (Hg) concentrations<br />

in muscles and stomach content samples were determined by Mercury Analyzer (MA-<br />

3000). The result showed that Thunnus tonggol are mainly consumed small fish,<br />

Rastrelliger kanagurta consumed small fish and worms, Euthynnus affinis mostly<br />

consumed shrimp, small fish, mollusks and worm while Scomberomorus guttatus<br />

consumed fish and squid. Overall, the Hg levels in dorsal muscle and separated<br />

stomach content for each species (n=40) does not exceed the permitted levels of<br />

Malaysian and JECFA guideline values at 0.5 mg/kg methylmercury in fish.<br />
