Diagnostic Description
provided by Fishbase
Dorsal and anal fins in adults with scales, without basal sheath of scales, and not fully depressible Interorbital space in adults strongly convex, the profile notably arched. Scales on caudal peduncle forming a graded size series with those on the bases of the midcaudal peduncle rays.
Migration
provided by Fishbase
Oceanodromous. Migrating within oceans typically between spawning and different feeding areas, as tunas do. Migrations should be cyclical and predictable and cover more than 100 km.
Morphology
provided by Fishbase
Dorsal spines (total): 0; Dorsal soft rays (total): 33 - 36; Analspines: 0; Analsoft rays: 27 - 30
Trophic Strategy
provided by Fishbase
Oceanic species which occurs near the surface (Ref. 2850). Feeds on cephalopods, fish and invertebrates (Ref. 4563).
Biology
provided by Fishbase
Oceanic species which occurs near the surface (Ref. 2850). Feeds on crustaceans (amphipods and euphausiids), small fishes and squid (Ref. 4563). Rarely caught inshore (Ref. 2850). Good food fish (Ref. 6885).

分布
provided by The Fish Database of Taiwan
主要分布在北太平洋亞熱帶至亞寒帶海域，包括白令海、日本近海、台灣、菲律賓等水域。台灣主要分布於北部海域。
利用
provided by The Fish Database of Taiwan
漁期全年皆有，可利用延繩釣漁法捕獲，通常本種魚都是偶獲，數量並不多，故並非台灣主要經濟魚種。一般市場亦不常見，魚肉尚佳，紅燒或煮味噌湯皆可。
描述
provided by The Fish Database of Taiwan
體呈卵圓形，側扁而高；頭背部圓凸。口大形，傾斜。吻鈍；下頜突出。上下頜及腭骨均有纖細牙齒。體被細鱗，鱗片中央有稜突或棘；體側縱列鱗數65-75。無側線；背鰭及臀鰭上被有細鱗，但基底無鱗鞘；尾鰭基部上的鱗與尾柄上的鱗比較，僅緩慢而漸次的變小。背鰭單一，起點在鰓蓋之後，不特別延長；臀鰭起點明顯在胸鰭基部後的下方，不特別延長；左右腹鰭相當接近；尾鰭叉形。體色為銀白色至銀灰色，死亡後魚體迅速轉變為灰褐色至黑褐色。背、尾鰭暗色；其餘各鰭淡色或稍暗。
棲地
provided by The Fish Database of Taiwan
大洋性底棲魚類，白天棲息於150-400公尺深的底層，夜晚則到水表層活動覓食。肉食性，以其他的魚類、甲殼類及頭足類等為主食。
Brama japonica
provided by wikipedia EN
Brama japonica, the Pacific pomfret, is a species of marine ray-finned fish, a pomfret of the family Bramidae. B. japonica is closely related, and quite similar, to Brama brama, but can be distinguished by possessing a greater number of anal fin rays and a higher number of gill rakers.[1]
Distribution and habitat
The type specimen for this species was from Japan and this is why it is named "japonica",[2] though its range extends much further than Japan. Brama japonica is widely distributed throughout the Pacific Ocean, from the Sea of Japan to California and Peru, notably in the Northern Pacific.[3][2] Its also been reported in Taiwan and the Philippines.[2] Like many bramids, this species can be found throughout the high seas and is highly migratory,[1] but oceanodromous.[2] Though rarely caught inshore, it is a good food fish.[2]
Pacific pomfrets are found at depths from 271 to 620 meters. [2]
Anatomy and appearance
Size
Averaging 30-42 cm in length, there have also been specimens reaching as great as 61cm. [2] Although the maximum published weight for the species in 2.7kg (5.95lbs),[2] the state record catch for a Pacific pomfret in Washington State is only 0.68 lbs. (0.3kg) [4]
Diet
Diet of adult B. japonica has been found to primarily consist of cephalopods and fish (primarily those in the genus Bathylagus), and secondarily amphipods.[5]
