Laemonema longipes Schmidt

Diagnostic Features: Body depth at anus about 7 or more times in standard length. Eye diameter less than snout and postorbital length of head. No barbel at tip of lower jaw, which is slightly longer than upper. No elongated filament in first dorsal fin; both pectoral and pelvic fins extending beyond origin of anal fin.

Geographical Distribution  : Central Japan to the Okhotsk and Bering Seas (Fig. 786).

Habitat and Biology: Benthopelagic on the continental slope, from 455 to  1  400 m depth.

Size: Maximum total length 60 cm.

Interest to Fisheries: None at present. Locally abundant; many specimens taken from a whale stomach. Considered to be a promising potential resource. Experimental fishing has provided catch rates over  6t/h off

Genus with Reference: Lepidion  Swainson, 1838,  Nat.Hist.Fish.Amphib.Rept., 1:318.

Diagnostic Features: Chin barbel present. Jaw teeth granular, a patch of similar teeth present on vomer. First dorsal fin with five or more rays, one notably elongated; anal fin deeply indented at mid-length, originating on anterior half of body, pelvic fin with 5 to 8 rays, one or more variously elongated. Ventral light organ absent.

Habitat, Distribution and Biology: Benthopelagic fishes living on the continental slope and lower rise. Neither their taxonomy nor biology are well known. An outdated key is presented by Norman (1935). There may be a dozen or more species.

Interest to Fisheries: Marginal at present, but several species are locally abundant in deep water and may represent resources of potential interest
