Tenualosa toli or Ilsha Chandana is a shad of the Clupeidae family, available in western Indian Ocean and the Bay of Bengal to the Java Sea and the South China Sea. It may be found in Mauritius and the Cambodian Mekong near the Viet Nam border. It inhabits fast-flowing, turbid estuaries and adjacent coastal waters, ascending rivers to breed. T. Toli is distinguished from similar clupeids, except Hilsa kelee, by a distinct median notch in upper jaw. Biology of this protandrous hermaphrodite is presumed to be similar to that of T. ilisha, but the fewer gill rakers suggest an intake of larger species of zooplankton as food.
