A blue mackerel, Scomber australasicus, was recorded during monthly survey on the availability of coastal and marine fish in Bangladesh. The specimen was captured from the Bay of Bengal by operating commercial gill net. This historic occurrence represents the first record of blue mackerel in the Bay of Bengal. The species was previously reported from the nearest Vizhinjam Coast of Laccadive Sea in India. The report of S. australasicus in the area further enriches the ichthyofauna of the area and points to the need for further detailed studies for conservation initiatives with respect to such rare fishes.
