(East Asian minnows)
Etymology: Longiculter: Latin, longus = long + Latin, culter = knife (Ref. 45335). More on author: Fowler.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; pelagic; depth range - m (Ref. ), usually - m (Ref. ). Tropical; 0°C -
Asia: Chao Phraya basin in Thailand (Ref. 12041). Reported from the Mekong basin (Ref. 30857) The Cambodian species may be distinct from the one recorded from central Thailand (Ref. 12693).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm SL male/unsexed; (Ref. 30857)
Inhabits middle and upper water levels of large and medium-sized rivers (Ref. 12693). Little is known about this species, but it is apparently uncommon or at least localized in distribution. Probably a filter feeder (Ref. 12693).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00412 - 0.01842), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (28 of 100) .
