Short description Morphology | Morphometrics

Dorsal soft rays (total): 11; Anal soft rays: 8. Schistura notostigma differs from all congeners from peninsular India and Sri Lanka by the combination of the following characters: 6-7 wide, brown bars on the posterior half of the body; width of interspaces equal ½-1 times the width of the bars; black bar on caudal-fin base complete, narrower than the width of the interspaces on the body; emarginate caudal fin; incomplete lateral line ending beneath the dorsal-fin base; adpressed pelvic fin surpassing the anus; 7½ branched rays on dorsal fin; pelvic-fin origin beneath first branched dorsal-fin ray; 4-8 pre-operculo-mandibular pores; and suborbital flap in males absent (Ref. 116162).

Biology     Glossary (e.g. epibenthic)

Prefers to inhabit fast flowing streams with a rock or pebble substrate (Ref. 116162). Found usually browsing among pebbles in shallow, flowing water. Can ascend steep inclines and also occurs in even the highest mountain streams (Ref. 6028).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00297 - 0.01341), b=3.03 (2.85 - 3.21), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (17 of 100) .
