Краткое описание
определительные ключи | морфология | морфометрия
Has 45-53 lateral line scales; 16-18 branched dorsal rays; an upturned mouth; a greenish to greyish body; a large, vertically elongated, blackish blotch above pectoral fin; sometime a faint round blotch on the caudal peduncle.
Occurs at midwater to bottom depths in rivers, streams, canals and swamps. Large individuals also occur in impoundments. Moves into seasonally flooded habits that supply its preferred diet of mostly periphyton as well as leafy plants like aquatic macrophytes and inundated land plants. Also feeds on phytoplankton, filamentous algae and benthic algae. Begins to return to the river in October, with numbers steadily increasing until January, when they begin to decline again. Large individuals are sold fresh or dried and salted, smaller ones are made into prahoc (Ref. 12693).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00585 - 0.01962), b=3.08 (2.93 - 3.23), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.3 ±0.18 se; based on food items.
устойчивость к внешним воздействиям (Ref.
120179): низкий, минимальное время удвоения популяции 4.5-14 лет (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (49 of 100).
