Short description Identification keys | Morphology | Morphometrics

Adults form small shoals in midwater above or near rocky reefs or above seagrass meadows (Posidonia. They feed on small planktonic or benthic animals (Ref. 6760). Reproduce in summer (Ref. 6760). Eggs characterized by adhesive filaments are nested on rocky or sandy bottoms (Ref. 6760). Males guard the eggs (Ref. 6760).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Breed on rocky or sandy bottoms (Ref. 6760). Males guard the eggs (Ref. 6760).

Estimates based on models

Preferred temperature (Ref. 123201): 16.2 - 27.8, mean 20.1 °C (based on 208 cells).

Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01230 (0.00972 - 0.01557), b=2.95 (2.88 - 3.02), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.4 se; based on diet studies.

Generation time: 4.8 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (35 of 100). 🛈

Climate Vulnerability (Ref. 125649): Low to moderate vulnerability (27 of 100). 🛈

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 35.3 [16.4, 75.9] mg/100g; Iron = 0.564 [0.326, 0.937] mg/100g; Protein = 19.8 [18.8, 20.8] %; Omega3 = 0.227 [0.137, 0.370] g/100g; Selenium = 11.9 [5.9, 23.6] μg/100g; VitaminA = 79.5 [27.3, 240.2] μg/100g; Zinc = 0.895 [0.583, 1.322] mg/100g (wet weight);
