Short description Identification keys | Morphology | Morphometrics

Differs from Taurulus bubalis by the row of bony knobs above the rough lateral line and by the 2 soft rays in the anal fin (Ref. 35388).

Biology     Glossary (e.g. epibenthic)

Found on hard bottoms (gravel or shells) or among algae with temperatures ranging below 0°C. Feeds on small crustaceans (amphipods, decapods) and fishes. Spawns in early spring. Eggs demersal, in clumps on bottom, diameter 2 mm; larvae pelagic (Ref. 4698).

Estimates based on models

Preferred temperature (Ref. 123201): 7.7 - 12, mean 10.2 °C (based on 488 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00281 - 0.01234), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.62 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 (10 of 100).
Nutrients (Ref. 124155):  Calcium = 145 [55, 366] mg/100g; Iron = 0.442 [0.203, 1.010] mg/100g; Protein = 17.5 [15.3, 19.7] %; Omega3 = 0.671 [0.275, 1.722] g/100g; Selenium = 5.65 [1.24, 18.26] μg/100g; VitaminA = 43.2 [13.1, 138.2] μg/100g; Zinc = 1.09 [0.67, 2.01] mg/100g (wet weight);
