A general term for fish with a reddish body color. It is used to refer to blue fish (aosakana), which have a bluish body color. It is different from red fish, whose flesh itself is red. Representative examples include sea bream, cod, ocean perch, flounder, gurnard, and scorpion. Compared to the spindle-shaped body shape common to blue fish, red fish have a significantly laterally or longitudinally flattened shape, a large head, and a well-developed skeleton. Red fish generally live on or near the bottom of the ocean, have low mobility, and do not migrate on a large scale. They mainly eat small fish that live on the ocean floor, shrimp, crabs, shellfish, polychaetes, sea urchins, and starfish. Their muscles are whitish, and they have little extract and fat content, so they have no particular flavor. They also rarely cause food poisoning compared to blue fish, and are less likely to spoil. For this reason, they are suitable for feeding to young children and sick people. Furthermore, in Japan, red is traditionally used to designate lucky items, so representative red fish such as sea bream and Pacific cod are used for celebrations as auspicious fish.

体の地色が赤みを帯びた魚類の総称。体色が青みを帯びた青魚(あおざかな)に対して用いる。魚肉自体が赤い赤身魚とは異なる。タイ類、タラ類、メヌケ類、ヒラメ・カレイ類、ホウボウ・カナガシラ類などがその代表である。体型は青物に多い紡錘形に比べて、著しく側扁(そくへん)または縦扁して扁平な形をしており、頭が大きく、骨格がよく発達している。赤物は一般に海底またはその近くにすみ、移動能力が低くて大規模な回遊をしない。海底にすむ小魚、エビ・カニ類、貝類、多毛類、ウニ類、ヒトデ類などをおもに食べる。筋肉は白みを帯び、エキス分や脂肪含量が少ないので味に特別な癖がない。また青魚に比べて食中毒にかかることがほとんどないうえ、変敗しにくい。そのため幼児や病人用の食事にも適している。また、日本では伝統的に縁起物に赤色を使うことが多いことから、赤物の代表格のタイ類、メヌケ類などは、めでたい魚として祝い事に用いられる。 [落合 明・尼岡邦夫] [参照項目] |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
