Comments: Ranges from the Inland Sea of Japan to Hokkaido (Ref. 559); including Sagami Bay (Ref. 39393). Also from western Kyushu (excl. Ryukyu Islands) (Ref. 11230). Two genetically different lineages were found in Japan Sea/East Sea, perhaps representing two different species (J.K. Kim, oral.comm, FishBoL2012, June 2012).

Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 0; Rückenflossenweichstrahlen (insgesamt): 55-59; Afterflossenstacheln 0; Afterflossenweichstrahlen: 28 - 32; Wirbelzahl: 62 - 67. Characterized by having a horizontal skin fold along its ventral contour, and the absence of pelvic fin and teeth. Lateral plicae 160 to 180. Lower jaw pointed. Lateral line system on head not continuous with that on the body.

Found in sand bottoms and may enter semi-enclosed sea areas (Ref. 11230). Forms large schools. Important food fish in Japan (marketed fresh or dried) and marketed fresh but mainly used for meal and oil manufacture in Europe (Ref. 10384). Common size taken from picture in Ref. 559. Maximum size estimated as 1.5 * common size. Two genetically different lineages were found in Japan Sea/East Sea, perhaps representing two different species (J.K. Kim, oral.comm, FishBoL2012, June 2012).

Estimates based on models

Preferred temperature (Ref. 115969): 11.9 - 23, mean 19.1 (based on 74 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00524 - 0.01907), b=3.23 (3.06 - 3.40), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.1 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (K=0.6).

Prior r = 0.79, 95% CL = 0.52 - 1.18, Based on 4 stock assessments.

Fishing Vulnerability (Ref. 59153): Low vulnerability (14 of 100).

Climate Vulnerability (Ref. 125649): Low vulnerability (17 of 100).

Preiskategorie (Ref. 80766): Very high.
