Known as ikan terubok in Malaysia, T. toli is highly prized among Malaysians for its meat and eggs. Overfishing has depleted the population alarmingly in South East Asia,[5] Regular breeding is carried out by local farmers in peninsular Malaysia to prevent extinct fish species.[6] In Bangladesh, where it is known as Ilisha Chandana (চন্দন ইলিশ), it is commercially less important than T. ilisha.[7][8] It is known as ငါးသလောက် • (nga:sa.lauk) /ŋəθəlaʊʔ/ in Myanmar, Trey Palung in Cambodia, Bhing in Maharashtra, Palwa in Gujarat, and Ullam / Seriya in Sri Lanka.[9]

In Thailand T. toli was called Pla talumpuk (ปลาตะลุมพุก) or Pla lumpuk (ปลาหลุมพุก), its name is origin of Laem Talumphuk (Talumphuk Cape) in Amphoe Pak Phanang, Nakhon Si Thammarat Province, due to in the past, this place is found abundant T. toli.[10]

Ascending rivers to breed. T. toli is distinguished from similar clupeids, except Hilsa kelee (kelee shad or five spot herring), by a distinct median notch in upper jaw. Biology of this protandrous hermaphrodite[11] is presumed to be similar to that of Tenualosa ilisha, but the fewer gill rakers suggest an intake of larger species of zooplankton as food.[12]
