Uses: live export: yes;
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).

Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 55-59; Anal spines: 0; Anal soft rays: 28 - 32; Vertebrae: 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 of some properties based on models

Phylogenetic diversity index (Ref. 82805)
PD₅₀ = 0.5156 many relatives (e.g. carps) 0.5 - 2.0 few relatives (e.g. lungfishes)

Trophic Level (Ref. 69278)
3.1 ±0.1 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278)
High, minimum population doubling time less than 15 months (K=0.6)

Vulnerability (Ref. 59153)
Low to moderate vulnerability (26 of 100)

Price category (Ref. 80766)
Very high
