scad 的詞源

大約1600年，一種在英國海岸豐富的魚類被稱爲康沃爾魚（Cornish），也被稱爲 horse mackerel，其名稱來源不確定，可能是 shad 的變體。《牛津英語詞典》將其與威爾士語 ysgaden “鯡魚”，挪威方言 skad，瑞典語 skädde “比目魚”進行了比較。

In July, 1834, as Mr. Yarrell informs us, most extraordinary shoals passed up the channel along the coast of Glamorganshire; their passage occupied a week, and they were evidently in pursuit of the fry of the herring. The water appeared one dark mass of fish, and they were caught by cart-loads, and might even be baled out of the water by the hands alone. ["British Fish and Fisheries," 1849] 

據雅瑞爾先生1834年7月的消息，格拉摩根郡海岸沿線出現了最不尋常的魚羣； 它們的行進持續了一個星期，顯然是在追逐鯡魚的魚苗。水面上一片黑壓壓的魚羣，它們被一車一車地捕撈，甚至可以用手直接從水中撈出。【《英國魚類和漁業》（1849）】
