Four species of fishes from the family of Nemipteridae, Scolopsis taenioptera,
Nemipterus furcosus, Nemipterus hexodon and Nemipterus nemurus were obtained
from the landing port at Pulau Kambing for the assessment of the mercury and the
food composition. Each species had 10 samples (n=10), for mercury concentration in
the muscle and their food composition to be determined and compared. Provisional
Weekly Tolerance Intake (PWTI) and length-mercury relationship between species
were determined. The mercury was measured by using the Mercury Analyser (MA-
300), where 15-20 mg of muscle and food items from four species used to find the
concentration of mercury. TrophyLab2K was used to check the trophic level of fish.
The result shown that Scolopsis taenioptera had highest mercury concentration in
muscle than other species and exceeded the tolerable value intake of mercury which
is 1.6µg/kg body weight based on JECFA. As the conclusion, carnivorous fish have
high content of mercury.
