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.

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

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.

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.
