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 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.
