It can be expected also on the west coast of Chile, but its presence there, as well as in other regions where it has been reported must be confirmed.

Estimates based on models

Preferred temperature (Ref. 123201 ): 2.8 - 4.4, mean 3.4 °C (based on 39 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00191 (0.00124 - 0.00292), b=3.21 (3.08 - 3.34), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.7   ±0.64 se; based on food items. Resilience (Ref. 120179 ):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  Moderate to high vulnerability (52 of 100). Climate Vulnerability (Ref. 125649 ):  Moderate to high vulnerability (49 of 100). Price category (Ref. 80766 ):   Low . Nutrients (Ref. 124155 ):  Calcium = 17.8 [9.8, 39.5] mg/100g; Iron = 0.359 [0.180, 0.729] mg/100g; Protein = 16.8 [14.7, 18.9] %; Omega3 = 0.218 [0.100, 0.463] g/100g; Selenium = 26.8 [10.7, 60.5] μg/100g; VitaminA = 8.17 [1.71, 36.62] μg/100g; Zinc = 0.369 [0.242, 0.575] mg/100g (wet weight);
