Biology     Glossary (e.g. epibenthic)

Adults inhabit lakes, ponds, sloughs, and backwaters and pools of streams (Ref. 1998, 10294). They usually occur among vegetation over mud or sand, most common in clear water. They form schools (Ref. 1998). Feed early in the morning, from midnight to 2 am (Ref. 1998). Individuals up to 16 cm feed on planktonic crustaceans and free-swimming, nocturnal, and dipterous larvae; larger individuals feed on small fishes (Ref. 1998, 10294). May be preyed upon by other fishes (Ref. 1998).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Nests are built by males, by clearing an area on the sand, mud or gravel bottom. Females probably spawn with different males in more than one nest (Ref. 1998). Males guard the eggs for about 5 days (Ref. 93240).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00903 - 0.01331), b=3.06 (3.00 - 3.12), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.62 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.11-0.45; tmax=13; Fec=26,700).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (53 of 100) .
Price category (Ref. 80766):   Unknown.
