Teleostei (teleosts) > Pleuronectiformes (Flatfishes) > Pleuronectidae (Righteye flounders) > Hippoglossinae
Etymology: Hippoglossus: Greek, ippos = horse + Greek, glossa = tongue (Ref. 45335); stenolepis: From the Greek hippos (horse), glossa (tounge), steno (narrow), lepis, (scale). In 1904, a Russian scientist by the name of P.J. Schmidt first proposed the scientific name based on anatomical differences such as scale shape, pectoral fin length, and body shape which he thought distinguished it from the Atlantic halibut (Hippoglossus hippoglossus). (Ref. 94075).

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

Marine; demersal; oceanodromous (Ref. 51243); depth range 0 - 1200 m (Ref. 50550). Temperate; 73°N - 42°N, 138°E - 123°W (Ref. 54557)

Max length : 258 cm TL male/unsexed; (Ref. 40637); 267.0 cm TL (female); max. published weight: 363.0 kg (Ref. ); max. reported age: 55 years (Ref. 55701)

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 90 - 106; Anal spines: 0; Anal soft rays: 69 - 80; Vertebrae: 49 - 51. Dorsal origin above anterior part of pupil in upper eye, generally low, higher in middle. Caudal spread and slightly lunate. Pectorals small.

Found on various types of bottoms (Ref. 2850). Young are found near shore, moving out to deeper waters as they grow older (Ref. 6885). Older individuals typically move from deeper water along the edge of the continental shelf where they spend the winter, to shallow coastal water (27-274 m) for the summer (Ref. 28499). Feed on fishes, crabs, clams, squids, and other invertebrates (Ref. 6885). Utilized fresh, dried or salted, smoked and frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988).

Estimates based on models

Preferred temperature (Ref. 115969): 0.3 - 5.7, mean 1.6 (based on 454 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00631 (0.00398 - 0.01000), b=3.14 (3.00 - 3.28), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.1 ±0.2 se; based on diet studies.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (rm=0.2; K=0.05; tm=5-20; tmax=55).

Prior r = 0.11, 95% CL = 0.07 - 0.17, Based on 3 full stock assessments.

Fishing Vulnerability (Ref. 59153): Very high vulnerability (86 of 100).

Climate Vulnerability (Ref. 125649): Moderate to high vulnerability (45 of 100).

Price category (Ref. 80766): Very high.
