Cuisine & Edibility

Great Hammerhead Shark

Critically Endangered — consumption strongly discouraged. Fins are historically traded but the species faces severe population decline; eating this fish is ecologically irresponsible.

ウォールアイ

Considered one of the best-tasting freshwater fish; sweet, flaky white flesh with very low fat. Ideal pan-fried, battered, or baked — a North American culinary favorite.

Species Overview

Great Hammerhead Shark

The great hammerhead is the largest of the nine hammerhead shark species. Its distinctive cephalofoil (hammer-shaped head) houses an array of electroreceptors that allow it to detect stingrays buried beneath the sand.

ウォールアイ

The walleye is the largest member of the perch family and the most sought-after freshwater food fish in North America. Its reflective eyes give it exceptional low-light vision, making dawn and dusk prime feeding times.
