Spine dorsali (totale) : 11; Raggi dorsali molli (totale) : 10 - 11; Spine anali: 3; Raggi anali molli: 8. Reddish, bronzy or golden-yellow in color; young with a blotch behind dorsal fin.

Biologia     Glossario (es. epibenthic)

Found near rocky banks in coastal waters including estuaries. Adults solitary and territorial. Feeds on octopus, crabs and fish, especially Spondyliosoma. The flesh is highly esteemed, but the liver is poisonous due to high vitamin A content which causes hypervitaminosis. Popular angling fish. Largest of the porgies.

Estimates based on models

Preferred temperature (Ref. 123201): 15 - 24, mean 22.2 °C (based on 10 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01549 (0.00889 - 0.02698), b=3.04 (2.89 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  4.5   ±0.61 se; based on food items.
Generation time: 14.6 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilienza (Ref. 120179):  Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (K=0.08; tm=5-7; tmax=30;).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (80 of 100).
Climate Vulnerability (Ref. 125649):  Very high vulnerability (92 of 100).
