Biology     Glossary (e.g. epibenthic)

Adults inhabit torrential hill-streams in shallow waters (Ref. 4832). They migrate to warmer regions of lakes and streams during winter (Ref. 40974). Used commonly by anglers as bait for Raiamas bola and Tor putitora. Herbivorous (Refs. 40948, 56237). Highly esteemed as food.

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00531 - 0.01717), b=3.03 (2.88 - 3.18), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.00 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (50 of 100).
