Biology     Glossary (e.g. epibenthic)

Benthopelagic (Ref. 58302). Collected from depths of 6 to 46 m. Sexual maturity at about 12.7 cm. Spawning period occur from February through May. Diet consists mainly of calanoid and cyclopoid copepods, but tunicates, mysids, euphausiids, crustacean larvae, larval polychaetes, siphonophores, and fish eggs are also taken (Ref. 7247). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 9 - 20.8, mean 14.6 °C (based on 14 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00571 - 0.02773), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.0 se; based on diet studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
