Length at first maturity / Size / Peso / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm TL maschio/sesso non determinato; (Ref. 7251); common length : 11.0 cm TL maschio/sesso non determinato; (Ref. 12193); Età massima riportata: 7 anni (Ref. 51483)
Adults inhabit coastal waters. They also enter fresh waters, going hundreds of miles upstream. Migrate downstream to spawn in spring (Ref. 36739). Larvae move upstream after hatching (Ref. 36739). Minimum depth reported taken from Ref. 57178.

Estimates based on models
Preferred temperature (Ref.
123201): 11.4 - 24.5, mean 17.2 °C (based on 60 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01318 (0.00764 - 0.02276), b=3.07 (2.92 - 3.22), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.5 se; based on size and trophs of closest relatives
Generation time: 5.6 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
