Sea Trout
Sea trout is the anadromous form of brown trout (Salmo trutta) that feeds at sea and returns to rivers—also called sewin in Wales. Flesh is pink to orange, richer than most river trout and milder than big wild salmon, with medium flakes and good oil. Size is often smaller than Atlantic salmon, ideal for whole baking or two generous fillets. British and northern European cookery smoke, grill, and poach sea trout in season. Treat like a delicate salmon: do not overcook, and keep the skin on for pan work. Wild runs are seasonal and conservation-sensitive; farmed rainbow marketed as “sea trout” in some places is a different product—read labels carefully.

Oily fish store long-chain omega-3 fats in the flesh—far richer than white fish.
History
Coastal and river fishing for sea trout and related species supplied essential protein long before agriculture spread globally.
Salting, drying, smoking, and fermenting extended the shelf life of sea trout and enabled long-distance trade.
Ice preservation and railway transport brought fresh sea trout to inland cities beyond fishing ports.
Industrial freezing, aquaculture, and global logistics made sea trout widely available in international markets.
