龙羊峡 / Longyangxia

Longyangxia / 龙羊峡 is the highland cold-water trout case in EP260 一口肥美脂肪，藏着中国养殖的新故事. The episode presents its reservoir environment as a reason domestic [[RainbowTrout|虹鳟]] can be farmed at scale and sold as sashimi, smoked fish, children’s foods, and other prepared products.

The source uses Longyangxia to make aquaculture infrastructure visible: cold water, deep net cages, parasite testing, fish-waste collection, feed delivery, water depth, and quick harvest-to-table logistics are all part of the freshness and safety claim.
