Salmon was first proposed by Hong Kong and Taiwan, which is a transliteration of the English name Salmon. This is because the English pronunciation of salmon is similar to that of Cantonese "Sanwen". Salmon is not a taxonomic name of fish, but a commercial name of some salmon or salmon trout.

Salmon is a general term. Salmon is a transliteration of English salmon, which means "salmon" in English. Salmon is divided into salmon and salmon, so salmon is trout. There are two kinds of trout in Salmonidae: salmon trout and rainbow trout.
