Occurs mainly in the open sea, occasionally approaching the shore and sometimes forming large schools. Rises to the surface in the spring months, but descending to as much as 78 m in late summer (apparently rising again in October-November, but descending once more in winter). Breeds intermittently from end of April to November, mainly in July, in the open sea.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00239 - 0.01051), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.00 se; based on food items.
Generation time: 3.9 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Fec=9,986-53,430).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (28 of 100).
