биология     глоссарий (например epibenthic)

Known to be gregarious, timid and nocturnal (Ref. 27188). Prefers deep still waters (Ref. 75964). Found in ponds (Ref. 11229) and creeks with a substrate rich in plant debris (Ref. 12225). This gymnotiform fish can be found in colder waters of 18°C (Ref. 10011). Electric organ discharge (EOD) frequency cues have been experimentally shown to play a role in species and sex recognition in this species (Ref. 10598). Playback of a conspecific male's electric courtship display elicited spawning in ripe females. Diel rhythmic change in EOD may be manifested by the increase in EOD amplitude at night among dominant breeding males as they compete with other conspecifics (Ref. 10599). A fractional spawner; fecundity reported at 905 eggs (Ref. 10605). Males reportedly reach 45 cm TL, females to 20 cm TL (Ref. 1672).

Life cycle and mating behavior Maturities | размножение | Spawnings | Egg(s) | Fecundities | личинки

Lays 100-200 eggs which adhere to leaves of aquatic plants (Ref. 27188).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00229 (0.00178 - 0.00295), b=2.89 (2.82 - 2.96), in cm Total Length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref. 120179):  средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (Fec=40-160 (per batch)).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (41 of 100).
