Actinopteri (ray-finned fishes) > Scombriformes
(Mackerels) > Centrolophidae
Etymology: Tubbia: Because of Mr. J. Allan Tubb (Ref. 45335); stewarti: Named for Andrew Stewart, an ichthyologist from New Zealand.
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 30 - 1438 m (Ref. 93030). Tropical
Southwest Pacific: confirmed from off Australia and New Zealand in the Southern Hemisphere'; possibly more widespread in the southern Indian Ocean but this needs confirmation.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 56.0 cm SL male/unsexed; (Ref. 93030)
The juveniles (6.1-9.9 cm SL) were collected from the epipelagic zone at 30-50 m depth; larger individuals (11.0-56.1 cm SL) occur much deeper in the mesopelagic zone at 525-1438 m depth (Ref. 93030).

Estimates based on models
Preferred temperature (Ref. 115969
): 8 - 13.4, mean 9.9 °C (based on 57 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00397 - 0.01999), b=3.10 (2.90 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (51 of 100) .
