Краткое описание
определительные ключи | морфология | морфометрия
членистые (мягкие) лучи спинного плавника (общее число) : 8 - 9; членистые (мягкие) лучи анального плавника: 9 - 10; позвонки: 29 - 30. A dark grey midlateral stripe, more intense posteriorly, not extending onto the caudal fin; dorsal-fin origin closer to the eye than to the caudal-fin base; 3 scale rows between the lateral line and the midventral row; caudal fin usually with a black posterior margin (Ref. 27732).
Occurs in a variety of habitats, but seems to prefer large rivers with slow current (Ref. 27732). Common along shores in large rivers (Ref. 56749). Found at or near the surface in clear waters of rivers and streams. Generally prefers a depth of about 5 m. Feeds mainly on exogenous insects, some small crustaceans and algae (Ref. 12693).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00376 - 0.01926), b=3.07 (2.87 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.9 ±0.36 se; based on food items.
Generation time: 2.9 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (K=0.38-0.69).
Fishing Vulnerability (Ref.
59153): Low vulnerability (21 of 100).
