Key identification features

  • Deep, strongly compressed body, growing to 45-60 cm
  • Bright silvery flanks with a golden sheen and a bluish-green back
  • Blunt, rounded snout and a small, oblique mouth
  • Sharp, saw-edged row of keeled scutes running the length of the belly
  • Deeply forked tail with dusky-tipped lobes
  • Single dorsal fin set at mid-body, usually no distinct dark spots

Common look-alikes

  • Toli shad: closely related and similarly shaped, but toli shad has a less sharply keeled belly and a different, generally more easterly range within South and Southeast Asian waters.
  • Indian oil sardine: much smaller and slimmer overall, lacking the pronounced body depth and ventral scutes of hilsa shad.
  • Other regional shads: hilsa's combination of golden flank sheen and strongly keeled scutes distinguishes it from plainer silvery shads.

Where you'll see one

Hilsa shad is an anadromous fish of the northern Indian Ocean, common along the coasts of the Bay of Bengal and Arabian Sea, migrating in large numbers up major rivers such as the Ganges, Padma, and Irrawaddy to spawn in fresh water.
