ABSTRACT: In Terengganu, Longtail tuna or Thunnus tonggol is one of the most popular marine fishes landed by
fishermen and has a high demand among customers. This species often served with
a unique local delicacy called Nasi
Dagang and Ikan Singgang, one of
the favourite meals during breakfast by local communities. Since people have
always consumed this species, therefore this study aims to identify the
consumption rate of this species among Terengganu people. Specifically, this
survey data obtained from 124 respondents, ages ranged from 15 to 60 years old
from five districts in Terengganu, including Besut, Kuala Nerus, Kuala
Terengganu, Hulu Terengganu, and Kemaman. Generally, the estimated amount of
this species consumption is 239.7 g per person and 1.83 times per week. From
the formula calculated, the amount of this species consumed by one person is
437.4 g/person/week. This value can use to calculate the permissible tolerable
weekly intake (PTWI) to estimate the intake of pollutants, such as heavy metals
in the human body.
