Common Hairfin Anchovy

Belly with 18 to 20 (rarely 17 or 21) + 7 (sometimes 8) = 25 to 27 keeled scutes from isthmus to anus. Lower gill rakers with the serrae uneven, with slight or sometimes distinct clumps of larger serrae. Pectoral filament moderate, reaching back to base of 9th to 21st anal fin ray.

Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Dorsal spines (total): 0; Analspines: 0; Analsoft rays: 46 - 56

Occurs in inshore waters of the continental shelf (Ref. 75154). Presumably schooling and mostly coastal, but also entering estuaries and penetrating at least 20 km upstream. Feeds on fish, benthic organisms and zooplankton (Ref. 189).

Presumably schooling and occurring mostly in coastal waters, but also entering estuaries (Ref. 11230) (e.g. the Hooghly and Godavari in India) and penetrating at least 20 km up the Godavari, tolerating salinities as low as 8.7 ppt. Feeds on prawn, copepods, crustacean larvae, mollusks and fishes. Fairly common (Ref. 189).

分布於印度-西太平洋區(24°N～8°S)，西起孟加拉灣、泰國、爪哇，西至南中國海及菲律賓，北至中國、日本、韓國等。臺灣北部、西部、南部及澎湖海域有產。

沿海常見之魚種，全年可產，中南部海域較多，主要漁法為近海拖網、流刺網，一般除鮮食外多曬成魚乾，或作為魚餌用。

體長而側扁，背緣隆突，腹緣自胸鰭部至肛門前，皆具銳利稜鱗。頭小而側扁。眼小，前側位。口大而斜，上頜稍長於下頜，不達鰓蓋骨末端；兩頜、鋤骨、腭骨及舌上均具細齒。體被圓鱗，鱗中大，易脫落，無側線；背鰭前方1棘狀稜鱗；胸、腹鰭的基部有腋鱗。背鰭短，起點與臀鰭起點相對或略後，具軟條13-14；臀鰭低而長，具軟條50-56。胸鰭位低，第1軟條延長如絲；尾鰭叉形。體背側呈暗灰黃色，腹部銀白色略帶黃色。背鰭末端及尾鰭後緣灰黑色，其餘各鰭灰白色。以前所記載之黃鯽(/Setipinna taty/)為本種之誤鑑。

近沿海洄游性魚類，常於河口域出現，具群游性。濾食性。
