Life cycle and mating behavior
Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve
Oviparous (Ref. 101737). Distinct pairing (Ref. 205). Females produce numerous eggs in multiple spawnings during a prolonged spawning period (Ref. 101737).

Estimates based on models
Preferred temperature (Ref.
123201): 21.1 - 28, mean 25.7 °C (based on 862 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00661 - 0.01047), b=3.10 (3.03 - 3.17), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.1 se; based on diet studies.
Generation time: 2.4 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (tmax=1.2; k >0.3).
Fishing Vulnerability (Ref.
