Anchovy

Diagnosis: Body fairly compressed, belly with 16-18 plus 9-10, with a total of 25-28 keeled scutes; lower gill rakers 10-12; head with gold tints; anal and caudal fins deep yellow; a black area behind upper part of gill opening (Ref. 189). It is distinguished from all other Thryssa species and in fact all other anchovies by the very long maxilla, reaching at least to tip of pectoral fin, usually to pelvic fin base or even to anal fin origin; also unique is the high coronoid process of the lower jaw, the jaw rising steeply in the mouth (Ref. 189).Description: Body fairly compressed (Ref. 189). Maxilla very long, reaching at least to tip of pectoral fin (Ref. 189, 2871, 30573). Lower gillrakers on first arch 10 to 12, upper gillrakers 6; branchiostegal rays 10 (Ref. 189, 5430, 30573). Dorsal fin with 3 unbranched and 11-13 branched rays; anal fin with 3 unbranched and 29-36 branched rays; pectoral fin with 1 unbranched and 11-13 branched rays; pelvic fin with 1 unbranched and 6-7 branched rays (Ref. 5430, 122607). Scales on the lateral line 41-46 (Ref. 5430). Scutes present before and behind the pelvic-fin base; 16-18 pre-pelvic scutes and 8-10 post-pelvic scutes (Ref. 189, 5430, 30573, 122607).Colouration: Head with gold tints; anal and caudal fins deep yellow; a black area behind upper part of gill opening (Ref. 189).

Dorsal spines (total): 0; Dorsal soft rays (total): 14 - 16; Analspines: 0; Analsoft rays: 32 - 39

Presumably schooling, mostly (or always ?) close inshore, entering bays and estuaries (Ref. 189, 75154). Inhabits coral reefs (Ref. 58534). More data needed including some functional explanation for the extraordinarily long maxillae (Ref. 189).

Marine, pelagic, presumably schooling, occurring mostly close inshore, entering bays and estuaries (Ref. 189, 30573). Recorded at a temperature range of 26.0-29.0 °C in the Trinity Inlet system, Australia (Ref. 4959). It feeds mainly on crustaceans, like amphipods, zoea larvae, Acetes (Ref. 189, 30573). May be caught using ringnets (Ref. 5213). Used as bait in the tuna fishery in the South Pacific.

廣泛分布於印度-太平洋區，西起阿曼灣，東至所羅門群島等，北至臺灣，南至阿拉夫拉海、澳洲等皆產。臺灣各地皆產，以北部及澎湖海域較多。

主要漁法為焚寄網、底拖網及流刺網，全年可產，西部沿海產量較豐，體薄肉少，通常曬成魚乾出售，或製成魚粉作為飼料之原料。

體甚側扁，腹部在腹鰭前後均有一排銳利的稜鱗，腹鰭前16-18個，腹鰭後9-10個，共約25-28個。頭略小，側扁。吻鈍，吻長明顯短於眼徑。口大傾斜；上頜骨末端尖且延長，可達胸鰭之尖端；第一鰓弓下枝鰓耙數10-12。體被圓鱗，鱗中大，易脫落，無側線；背鰭前方具1小棘，胸、腹鰭具腋鱗。背鰭起始於體中部，具11-12軟條；臀鰭長，具34-38分枝之軟條；尾鰭叉形。體背部青灰色，具暗灰色帶，側面銀白色；鰓蓋後上角具一黃綠色斑駁。背鰭、胸鰭及尾鰭黃色或淡黃色；腹鰭及臀鰭淡色。

沿近海表層魚類，濾食性，以浮游動物為主，輔以多毛類、端腳類。亦常可於河口區及內灣區發現。

Thryssa setirostris, the longjaw thryssa, is a species of ray-finned fish in the family Engraulidae. It is found in the Indo-Pacific.
