Population genetics is the science of how genetic variation is distributed among
species, populations and individuals, and fundamentally, it is concerned with how the
evolutionary forces of mutation, selection, random genetic drift and migration affect
the distribution of genetic variability. The genetic diversity and genetic structure of
longtail tuna in Malaysia was examined using highly mutative mitochondrial DNA
(mtDNA) of ND5 among three populations with 53 individual samples. The salt
extraction method was used in lowered the cost of the research. There were 47
haplotypes obtained from the analysis. The finding was showing there were high
haplotype diversity at 0.991 and low nucleotide diversity at 0.009 among the three
populations, there were also no population structure among the populations. So, the
action of conserving this Thunnus tonggol should be taken by the country and required
all collaborations among the nearest countries to ensure its sustainable use.
