Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 2; Afterflossenstacheln: 0. Snout short, moderately pointed, with stout scutes at its tip and lateral angles; underside of the snout and suborbital anteriorly naked. Light organ not well-developed externally; no scaleless fossa between the pelvic-fin bases. Pyloric caeca 21 to 32. Body scales with conical spinules in 10 to 12 slightly convergent rows.

Most common grenadier in the Eastern central Pacific but occurs in very deep waters that it is not regularly taken by trawlers (Ref. 9315). Maximum TL of at least 30 cm (Ref. 9315).

Estimates based on models

Preferred temperature (Ref. 123201): 4 - 5.7, mean 4.9 °C (based on 48 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00214 (0.00109 - 0.00421), b=3.20 (3.03 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.1 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (20 of 100).

Preiskategorie (Ref. 80766): Medium.
