Chinese Seerfish

Interpelvic process small and bifid. Body covered with small scales. Lateral line abruptly curving down below first dorsal fin. Intestine with 2 folds and 3 limbs. Swim bladder present. Sides silvery with large round, indistinct spots in two poorly defined rows in adults. Juveniles with saddle-like blotches extending down to about middle of body.

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): 15 - 17; Dorsal soft rays (total): 15 - 17; Analspines: 0; Analsoft rays: 16 - 19; Vertebrae: 41 - 42

Feeds on fishes and swims well upstream river because of easy food availability (Ref. 12693).

Travels 300 km up the Mekong River, above Phnom Penh but believed to reproduce only in marine waters. Feeds on fishes and swims well upstream river because of easy food availability (Ref. 12693). No information on biology available (Ref. 9684). It is a prized food fish in Japan and probably in China as well. Utilized fresh, dried or salted and smoked; consumed pan-fried, broiled and baked (Ref. 9987).

分布於西太平洋區，由日本海南下至中南半島，甚至發現於泰國之眉公河。台灣主要分布於西部及北部海域。

重要之食用魚。一般以圍網、流刺網、定置網捕獲。煎食、味噌湯皆宜，亦可加工成鹽漬品或罐頭。

體延長，側扁；尾柄細，兩側在尾鰭基處各具3條隆起脊，中央脊長而高，其餘二脊短而低。頭中大，稍側扁。吻尖突，大於眼徑。眼較小，位近頭的背緣。口中大，端位，斜裂；上下頜等長，上下頜齒各具齒一列，齒強大，側扁，三角形，10-13枚，排列稀疏；腭骨及鋤骨亦具齒，舌上無齒。第一鰓弓上之鰓耙數為1-3+10-12。體被細小圓鱗，易脫落，側線鱗較大，腹部大部分裸露無鱗；側線完全，無分枝，沿背側延伸至第一背鰭後部急降至腹側，再呈波浪狀伸達尾鰭基。第一背鰭具硬棘XV-XVII，與第二背鰭起點距離近，其後具6-7個離鰭；臀鰭與第二背鰭同形；尾鰭新月形。體側灰綠色，腹部銀白色，成魚體側上方具10-12條不顥之不規則黑色窄橫帶，幼魚則呈點狀。

近海暖溫性中上層魚類，主要棲息於淺的大陸棚區，有時會出現於岩岸陡坡或潟湖區，亦出於現河口域，甚至被發現於泰國之眉公河。性凶猛，行動敏捷，成群捕食小型如鯷類之魚。
