Description

Tenualosa macrura was first described by Pieter Bleeker in 1852, is a species of shad in the order Clupeiformes. Found in tropical and subtropical waters of Southeast Asia, it inhabits coastal areas, estuaries, and river mouths, displaying an anadromous life cycle where it migrates upriver to spawn in freshwater. The fish is characterized by its streamlined, silvery body and an elongated tail and can reach a maximum length of 52 centimeters. Feeding primarily on plankton, it plays an essential role in the aquatic food web.

Biology

Fisheries

Tenualosa macrura is economically significant and is widely harvested for human consumption. However, overfishing, habitat loss, and pollution threaten its populations, highlighting the need for sustainable management and conservation efforts.
