Biology     Glossary (e.g. epibenthic)

Adults inhabit rocky inshore reefs (Ref. 9334). Omnivorous (Ref. 9334). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 18.8 - 25.9, mean 23.2 °C (based on 117 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.01198 - 0.03323), b=2.98 (2.84 - 3.12), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.00 se; based on food items.
Generation time: 4.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (tmax=11).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (34 of 100).
Nutrients (Ref. 124155):  Calcium = 90.7 [38.3, 153.6] mg/100g; Iron = 0.945 [0.514, 1.800] mg/100g; Protein = 18.8 [17.5, 20.1] %; Omega3 = 0.139 [0.071, 0.274] g/100g; Selenium = 12.4 [5.2, 30.2] μg/100g; VitaminA = 28.6 [5.7, 138.6] μg/100g; Zinc = 1.42 [0.85, 2.40] mg/100g (wet weight);
