Maturity: Lm 14.5  range ? - ? cm

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
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.00846 - 0.04293), 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).
