Sequence analysis of a fragment of the cytochrome b gene in Decapterus russelli sampled from the Indo‐Malay archipelago revealed two distinct mitochondrial clades (mean nucleotide divergence=2·2%) whose geographic distribution was heterogeneous (Nei's G ST =0·416). This pointed to a complex pattern of genetic differentiation and demonstrated limited genetic exchange between populations in this highly mobile species.
