Biologia     Glossario (es. epibenthic)

In coastal rivers and creeks (Ref. 42576). Pair-bonding, ovophilic mouthbrooder (Ref. 52307, 81260) with delayed uptake (Ref. 81260). Spawns on open substrates; both parents brood offspring (Ref. 81260).

Estimates based on models

Phylogenetic diversity index (Fonte Biblio. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Fonte Biblio. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Resilienza (Fonte Biblio. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Assuming Fec<1000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
