Like shark, skate is a cartilaginous fish. The most common skate in Norway is the thorny skate. Unlike other flat fish, its gill cleft and mouth sits underneath the head. The thorny skate lives in marine and brackish waters all along the Norwegian coast at a depth between 20 and 1000 metres. It is a bottom-dweller found on a variety of substrates. The thorny skate is slow growing, taking at least 5 to 10 years to reach sexual maturity. Skates copulate and have internal fertilization, spawning in the spring and summer. They produce relatively few eggs, which hatch as dark rectangular single- egg capsules with have characteristic horns in each corner. When they hatch from the capsules, they are fully formed fish. The thorny skate can live up to 20 years.
Skate fishing in Norway is modest, although significant quantities are caught as bycatch.
The thorny skate is sold as following product:
- The wings
Crustaceans, bony fish, and polychaete worms.
Skate is especially rich in:
- Protein that builds and maintains every cell in the body.
- Vitamin B12, which is important for the body to produce new cells, including red blood cells. Vitamin B12 can contribute to preventing anaemia.
- Selenium, an important element in an enzyme that fights harmful chemical processes in the body.
