<P><B>Abstract</B></P> <P>Mariculture fish contains a rich source of protein, but some species may bioaccumulate high levels of heavy metals, making them unsafe for consumption. This study aims to identify heavy metal concentration in <I>Lates calcarifer</I> (Barramudi), <I>Lutjanus campechanus</I> (Red snapper) and <I>Lutjanus griseus</I> (Grey snapper). Three species of mariculture fish, namely, <I>L. calcarifer</I>, <I>L. campechanus</I> and <I>L. griseus</I> were collected for analyses of heavy metals. The concentration of heavy metal (As, Cd, Cu, Cr, Fe, Pb, Mn, Ni, Se, and Zn) was determined using inductive coupled plasma mass spectrometry (ICP-MS). The distribution of heavy metals mean concentration in muscle is Zn > Fe > As > Se > Cr > Cu > Mn > Pb > Ni > Cd for <I>L. calcarifer</I>, Fe > Zn > Cr > As > Ni > Mn > Se > Cu > Pb > Cd for <I>L. campechanus</I> and Fe > Zn > Cr > Ni > Se > Cu > As > Mn > Pb > Cd for <I>L. griseus</I>. Among all of the species under investigation, the highest concentration of Fe was found in the muscle tissue of <I>L. campechanus</I> (19.985 ± 1.773 mg kg<SUP>−1</SUP>) and liver tissue of <I>L. griseus</I> (58.248 ± 8.736 mg kg<SUP>−1</SUP>). Meanwhile, <I>L. calcarifer</I> has the lowest concentration of Cd in both muscle (0.007 ± 0.004 mg kg<SUP>−1</SUP>) and liver tissue (0.027 ± 0.016 mg kg<SUP>−1</SUP>). The heavy metal concentration in muscle tissue is below the permissible limit guidelines stipulated by the Food & Agriculture Organization, 1983 and Malaysia Food Act, 1983. The concentration of heavy metals varies significantly among fish species and tissues. <I>L. campechanus</I> was found to have a higher ability to accumulate heavy metals as compared to the other two species (p < .00). Among all the studied fish, liver tissue has a higher concentration of heavy metals compared to muscle tissue (p < .05). The findings from this study can serve as baseline information for future monitoring and risk assessment studies. Periodic monitoring of heavy metal concentration in mariculture fish must be performed to prevent acute and chronic food intoxication.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Species were chosen due to the most extensive maricultured species in estuaries. </LI> <LI> Species chosen were the most consumable fish species in Asian region. </LI> <LI> High metals concentration had been observed in <I>L. campechanus.</I> </LI> <LI> Liver tissues possessed higher metal concentration than muscle tissues. </LI> <LI> Studied metals were below than the permissible limit. </LI> </UL> </P>
