Temperate Scad, Decapterus muroadsi (Temminck & Schlegel 1844)

More Info


Garden Island to north-west of Shark Bay, Western Australia, and Seal Rocks to New South Wales, and Lord Howe Island in the Tasman Sea. Elsewhere the species is widespread in warm temperate waters of the Indo-West Pacific, from southern Australia, Japan, the northwestern Hawaiian Islands, Rapa, Easter Island, Nazca Ridge and the eastern Pacific Ocean (Gulf of California to Peru). Although the Temperate Scad has been recorded from the mid-Atlantic Ocean (St Helena), this is thought to be a different species (Smith-Vaniz & Williams 2015).
Forms pelagic schools in oceanic and inshore waters.


Feeds mostly on planktonis invertebrates.
