虹鳟 / Rainbow Trout

Rainbow trout / 虹鳟 is the salmonid food case in EP260 一口肥美脂肪，藏着中国养殖的新故事. The episode uses domestic trout production to explain why “三文鱼” became a contested consumer label in China: rainbow trout and Atlantic salmon are related but not identical, and the practical question is whether restaurants and packages make that distinction visible.

The source links rainbow trout to [[Longyangxia|龙羊峡]] cold-water farming, parasite testing, water-quality management, astaxanthin-influenced flesh color, and freshness claims built around short harvest-to-table cycles. It also shows how one fish becomes multiple Chinese product forms: sashimi, cold-smoked slices, hot-smoked ready-to-eat portions, meat floss, small cakes, and children’s food.
