Biology     Glossary (e.g. epibenthic)

Very adaptive, found in almost every habitat type within its distributional range; feeds mainly on small fish, aquatic insects and crustaceans; females only spawn once a year, around September during the rainy season; spawns of approximately 200 eggs per female are possible; males excavate shallow craters in shallow waters for spawning (Ref. 52307).

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=0.01349 (0.00754 - 0.02415), b=2.98 (2.83 - 3.13), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.44 se; based on food items.
Generation time: 2.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (K=0.5).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (25 of 100).
Price category (Ref. 80766):   Unknown.
