Toli shad (Tenualosa toli)

Scientific name: Tenualosa toli Valenciennes, 1847

Toli shad (Tenualosa toli)

The Toli shad (Tenualosa toli) is a freshwater fish of the family Clupeidae. Native range: Indo-West Pacific, India to the Java Sea and the South China Sea. Newly recorded from Mauritius. May be found in Cambodian Mekong near the Viet Nam border.

Biology

Inhabits fast-flowing, turbid estuaries and adjacent coastal waters. Schooling in coastal waters, euryhaline and perhaps anadromous, ascending rivers to breed (but in some areas fishery workers claim that it does not). A protandrous hermaphrodite. Presumably its biology is similar to that of T. ilisha, but the fewer gill rakers suggest that it takes larger food organisms. Reported to feed on zooplankton. More data needed especially since it is not always distinguished from T. ilisha, especially at juvenile stages. Marketed fresh or dried-salted.
