Salmon

三文鱼

Salmon · not one fish, but a family

Stop 1/7

三文鱼 · 不是一种鱼, 是一类鱼

'Salmon' is a market name, not one biological species. It spans Atlantic salmon (>90% of the market is farmed) and several wild Pacific species — king, sockeye, coho, pink, chum.

The differences aren't just naming. Fat content, omega-3 level, flesh color, and price all track species and the farmed-vs-wild split. Farmed Atlantic salmon can carry 2-3× the fat of wild pink salmon, so the nutrition panel varies a lot under one label.

The orange-red flesh comes from a carotenoid called astaxanthin — wild fish accumulate it from krill, farmed fish get it from feed.

One thing up front: salmon sold for raw eating is often Atlantic salmon or rainbow trout, not wild Pacific salmon — which matters for whether it can be eaten raw.
