Listed as endangered on IUCN Red List.
The fish generally breed during floods and spawn over rocky, gravel substrates, often in ephemeral headwaters. Sexual productivity is low (6,000 – 10,000 eggs per kg). The individuals of the population grow at an average rate of 10cm annually. It is omnivorous in feeding habits. During migration, fish of all ages remain carni-omnivorous and the fish <46 cm size become piscivorous.
Conservation IssuesThe species have suffered severe population declines in much of its distribution range, and are now considered threatened due to pollution, habitat loss and over-fishing. There is dearth of information on habitat, feeding and breeding ecology of the species. Mahseer is a sensitive species that can barely tolerate a modified water environment. This is evident from the decrease in its size (length) recorded over the last century, size composition (predominance of young/ immature individuals) and reduced share in the catch (as low as 5% from 40-50%) from it’s distribution ranges.
Out of the 47 species of Mahseer that exist in the world, India is home to fifteen. Tor remadevi is one of the newest species identified while Tor moyarensis, confined to the Moyar river of Tamil Nadu, is reported to be another.
