Cuisine & Edibility
Grand requin marteau
Critically Endangered — consumption strongly discouraged. Fins are historically traded but the species faces severe population decline; eating this fish is ecologically irresponsible.
Perchaude
Sweet, clean white flesh with very low fat and a delicate texture; among the most prized freshwater eating fish in the Great Lakes region. Best pan-fried or sautéed simply in butter.
