Etymology: Hyporhamphus: Greek, hypo = under + Greek, rhamphos = beak, bill (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
生態學
海洋; 淡水; 半鹹淡水; 非產卵性溯降河的; 深度上下限 0 - ? m. 亞熱帶的
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.
西北太平洋: 日本本州與黃海的北部南至中國南部,包括台灣。 來自琉球群島的報告似乎不被由標本支撐而且可能是誤鑑。 然而，所有 Gushiken 的琉球相片 (除了這一個被分類的 Hyporhamphus intermedius 以外) 似乎確地被鑑定。
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm ?, range 10 - ? cm
Max length : 20.3 cm TL 雄魚/尚未辨別雌雄; (Ref. 114983)
背棘 (總數) : 0; 背的軟條 (總數) : 13 - 17; 臀棘: 0; 臀鰭軟條: 14 - 19; 脊椎骨: 47 - 54. Long upper jaw and many vertebrae (47-54) and predorsal scales (48-63). Lower jaw shorter than head length.
長的上頜與許多脊椎骨 (47-54) 與前背的鱗片.(48-63) 下頜短於頭長。
Enters estuaries and freshwater. Feeds on zooplankton.
進入河口與淡水水域。 吃浮游動物。

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 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).
營養階層 (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.
回復力 (Ref.
120179): 高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (21 of 100).
