Biology     Glossary (e.g. epibenthic)

Feeds on phytoplankton, higher plants and, to a lesser extent, zooplankton. Spawning season is from March to August and each specimen spawns at least 2-3 times during that period (Ref. 13609).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Also exhibit biparental care by mouthbrooding (Ref. 13609).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.00827 - 0.04391), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.00 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.63; tm=2).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (29 of 100).
