Mitochondrial marker implies fishery separate management units for spotted sardinella, (Walbaum, 1792) populations in the South China Sea and the Andaman Sea.

The spotted sardinella, (Walbaum, 1792), is a commercial sardine commonly caught in Malaysia. Lack of management of these marine species in Malaysian waters could lead to overfishing and potentially declining fish stock populations. Therefore, sustainable management of this species is of paramount importance to ensure its longevity.

Recent population expansion of longtail tuna (Bleeker, 1851) inferred from the mitochondrial DNA markers.

The population genetic diversity and demographic history of the longtail tuna in Malaysian waters was investigated using mitochondrial DNA D-loop and NADH dehydrogenase subunit 5 (ND5). A total of 203 (D-loop) and 208 (ND5) individuals of were sampled from 11 localities around the Malaysian coastal waters. Low genetic differentiation between populations was found, possibly due to the past demographic history, dispersal potential during egg and larval stages, seasonal migration in adults, and lack of geographical barriers.

Phylogeography of the Japanese scad, (Teleostei; Carangidae) across the Central Indo-West Pacific: evidence of strong regional structure and cryptic diversity.

The Japanese scad (Carangidae) is an economically important marine species in Asia but its exploitation shows signs of overfishing. To document its stock structure, a population genetic and phylogeographic study of several populations of this species from the central part of the Indo-West Pacific region was conducted using the mitochondrial cytochrome gene. Genetic homogeneity within the Sundaland region's population, including Rosario (the Philippines) and Ranong (Andaman Sea) populations was revealed with low nucleotide diversity ( = 0.
