Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 11; членистые (мягкие) лучи спинного плавника (общее число) : 11 - 13; колючие лучи анального плавника: 3; членистые (мягкие) лучи анального плавника: 10 - 11. Silvery with distinct crossbars (Ref. 3198).
Found over sandy substrate. Juveniles use estuaries as nurseries (Ref. 27121). Feeds on worms, crustaceans, and mollusks especially mussels (Ref. 5213). Spawns during spring and summer close inshore (Ref. 36731).

Estimates based on models
Preferred temperature (Ref.
123201): 14.5 - 26.4, mean 23.8 °C (based on 102 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00609 - 0.02604), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.2 se; based on diet studies.
Generation time: 6.9 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
устойчивость к внешним воздействиям (Ref.
120179): средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (K=0.16).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (54 of 100).
Climate Vulnerability (Ref.
