    We record the first capture from Laos of the diadromous eel-tail catfish Plotosus canius as a single specimen
    of total length 1111 mm from Phapheng Channel, which is the most easterly anabranch of the Mekong in the
    Khone Falls system in southern Laos. The capture location is about 2.5 km downstream of Phapheng Waterfall
    and about 2.1 km upstream of the Cambodian border with Laos. As the location is about 720 km from the sea
    and at least 500 km upstream of any possible saline influence, this record shows that some large individuals of
    this diadromous species, which breeds in brackish waters, may penetrate long distances into freshwaters, where
    they feed on crabs and molluscs.
