Cuisine & Edibility
Sockeye Salmon
Intense, deep-red flesh with a full, robust salmon flavor and high omega-3 content. Excellent grilled, smoked, or canned; its bold flavor stands up to strong seasonings and wood smoke.
Wels Catfish
Fatty, soft flesh with a mild, slightly sweet flavor; quality improves from cold, clean water fish. Popular in Central European cuisines — commonly smoked, fried, or braised with vegetables.
Species Overview
Sockeye Salmon
The sockeye salmon is famous for turning bright red during its upstream spawning migration. Its deep-red flesh is the richest in omega-3 fatty acids of all Pacific salmon species, making it the most valuable commercially.
Wels Catfish
The wels catfish is the largest freshwater fish in Europe, capable of exceeding 5 meters. Found in large rivers and lakes across the continent, it has been documented beaching itself to catch pigeons. It can live over 80 years.
