ここで見られる魚:サワラ


サワラ(Scomberomorus niphonius)

鳴門では、サワラが現れることは春が訪れる前触れです。毎年冬が終わる頃、この細長い魚は紀伊水道から北西に向かって泳ぎ、瀬戸内海の播磨灘で産卵をする前に鳴門海峡を通ります。夏から秋へと移る頃、この魚は寒さから逃れるためにもう一度鳴門海峡を通り、太平洋に再び移り住みます。

サワラは全長115cmになることがあり、また重量12kgの標本があったことが記録されています。この魚のメスはオスよりも大きく育ちます。大きな口と顎には鋭い歯が並んでいます。いくつかの黒みがかった斑点の列は、この魚の胴体全体に広がっており、また胴体の背側は青がかった灰色で、下側は銀白色となっています。鳴門の漁師は、サワラが春に通る際にこれを釣りや刺し網で捕ります。サワラは一般的に焼き魚にされたり、生で刺身として食されます。


Fish in the Naruto Strait: Japanese Spanish Mackerel


Japanese Spanish mackerel (Scomberomorus niphonius)

In Naruto, the appearance of the Japanese Spanish mackerel, called sawara in Japanese, heralds the arrival of spring. Every year when winter ends, these long, thin fish swim northward from the Kii Channel, passing through the Naruto Strait before spawning in the Harima-Nada region of the Seto Inland Sea. As summer turns to fall, they travel through the strait once again, migrating back to the Pacific Ocean in order to escape the cold.

The Japanese Spanish mackerel may reach 115 centimeters in total length; specimens weighing in at 12 kilograms have been recorded. The female of the species grows larger than the male. It has a large mouth and a jaw lined with sharp teeth; several rows of blackish spots extend the full length of the fish’s body, which is blue-gray on the dorsal area and silvery white on the underside. Naruto’s fishermen catch the Japanese Spanish mackerel by angling and gill nets when it passes through in spring, and it is commonly grilled or eaten raw as sashimi.
