CATDOLL : CATDOLL: Why is rainbow trout called salmon? Because they look similar.

1. Because rainbow trout is very similar to salmon, but it is not salmon. In recent years, the farming industry of rainbow trout has developed. The meat of large rainbow trout is almost the same as that of Atlantic salmon, and it is completely indistinguishable with the naked eye. In fact, the fat layer of some parts is thicker than that of salmon, making it look more like salmon.

2. Because some salmon are caught, then processed at low temperatures, transported, and processed, some fat may be dissolved, and they look exactly like rainbow trout. Therefore, when consumers buy salmon, they cannot tell the difference unless they buy the whole fish.
