Classification / Names Common names | Synonyms | Catalog of Fishes(genus, species) | ITIS | CoL | WoRMS | Cloffa

Teleostei (teleosts) > Perciformes/Scorpaenoidei (Scorpionfishes) > Sebastidae (Rockfishes, rockcods and thornyheads) > Sebastinae
Etymology: Sebastes: Greek, sebastes = august, venerable (Ref. 45335);  melanostictus: Greek, melas = black + Greek, stiktos = spotted or dappled; alluding to the spotted body coloration (Ref.87139)..

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; benthopelagic; depth range 84 - 1000 m (Ref. 87139), usually 350 - 450 m (Ref. 87139). Subtropical

Short description Morphology | Morphometrics

Dorsal spines (total): 12 - 14; Dorsal soft rays (total): 12-15; Anal spines: 3; Anal soft rays: 7 - 8; Vertebrae: 26 - 27. Head spines, 8; infraorbital spines, 2 or more; body coloration generally dusky with faint mottling on dorsum; spinous dorsal-fin and rest of body often spotted; dorsal-fin spine 1 longer, 1.0 to 1.8 times into orbit length, 5.9-9.6% SL; dorsal-fin spine 4 longer, 12.0-18.4% SL; gill rakers longer, 3.9-7.1% SL and more numerous in comparison to S. aleutianus. Genetically, with the protein variants ACP*46, either IDDH*500 or *750 or both, either PGM-2*83 or *74 or both, and XO*109 (Hawkins et al., 2005); homozygosity at microsatellite allele ?Sma6*177 (Gharrett et al., 2005, 2006); and mitochondrial haplotype A of Gharrett et al. (2005, 2006) (Ref.87139).

Estimates based on models

Preferred temperature (Ref. 123201): 0.9 - 3.8, mean 2 °C (based on 44 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00499 - 0.02004), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.5 se; based on size and trophs of closest relatives
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 (46 of 100).
