Northwest Pacific: Honshu, Japan and the northern part of the Yellow Sea south to southern China, including Taiwan. Reports from Ryukyu Islands do not seem to be supported by specimens and may represent misidentifications. However, all of Gushiken's Okinawa photographs (except the one labeled Hyporhamphus intermedius) seem to be correctly identified.

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00186 (0.00120 - 0.00289), b=2.96 (2.83 - 3.09), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.4 ±0.45 se; based on food items.

Generation time: 1.6 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).

Prijsklasse (Ref. 80766): Unknown.

Hyporhamphus intermedius (Cantor, 1842)
