Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 50.0 cm TL male/unsexed; (Ref. 1441); max. published weight: 1.5 kg (Ref. 56557); max. reported age: 10 years (Ref. 56527)

Spawns from May to September. Spent adults descend to sea after spawning. Immature specimens occur in the mouths of rivers the whole year round; the young descend to the sea upon attaining a length of 7-9 cm (Ref. 1441).

Estimates based on models

Preferred temperature (Ref. 115969): 2.6 - 18.3, mean 5.3 (based on 430 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00955 (0.00441 - 0.02066), b=3.07 (2.88 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.35 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).

Price category (Ref. 80766): Unknown.
