Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 55 - 59; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 28 - 32; Ryggkotor: 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.
Body shape (shape guide): elongated; Cross section: circular.
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).
