Biology     Glossary (e.g. epibenthic)

Mesopelagic, perhaps with diel migration (Ref. 58302). Usually caught singly, but also in small aggregations (Ref. 6345). Feed on plankton (Ref. 6345). Oviparous, with planktonic eggs and larvae (Ref. 35604). Minimum depth from Ref. 58018.

Estimates based on models

Preferred temperature (Ref. 123201): 3.2 - 13.8, mean 8.2 °C (based on 1243 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00247 - 0.01018), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.45 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (14 of 100).
