利用

provided by The Fish Database of Taiwan
為大眾化且常見之食用魚,幾乎全年都可以吃到,但是以10月到次年的3月為其盛產期,而這時候的魚肉質也最肥美。以一支釣、流刺網及拖網漁法均可捕獲。清蒸及油煎兩相宜。

Pacific rudderfish

provided by wikipedia EN

The Pacific rudderfish (Psenopsis anomala) is a marine fish also known by such names as Japanese butterfish, melon seed, wart perch, ibodai (Japanese name, イボダイ) or simply but ambiguously as butterfish.[1][2]

This fish, which can grow to 30 cm (12 in) TL, is found in the Western Pacific, near Japan, in the Taiwan Strait and in the East China Sea. The Japanese butterfish prefers tropical waters: around 42°N–19°N. It has been found in the waters near Hong Kong. Generally, they inhabit the epipelagic layer to 370 m (1213 ft). Adults are mainly bottom-dwelling, but migrate upward at night in search of food.[2]

The Japanese butterfish has a compressed body, somewhat oval-shaped, and is whitish to grayish in colour; in the young fish, the colour is darker: a pale brown or blackish brown. Some other features of this fish are a robust snout, a relatively small mouth, and the upper jaw extending to below the anterior margin of the eye. The fish's teeth are small, conical, and incisor-like. Spines of the Japanese butterfish's dorsal fin are short and not separated from the soft-rayed portion. The scales on the body of the butterfish are small, cycloid, and very deciduous (meaning that they are shed off easily).

This species is of economic importance, commercially sought after, and caught by trawl by Japanese and Taiwanese fishermen. The total catch reported for this species in 1999 was 10,871 t, with Taiwan (5,075 t), and Japan (4,996 t) making up nearly all the catch.[1]

The meat of the Japanese butterfish is very popular as food in its native range. It is said to be a tasty fish that can be steamed, pan-fried, or used in sushi.
