Thorncheek grouper (lat. Sebastolobus macrochir) is one of the species of groupers. Belongs to the rockfish, as a deep waters representative (from 300 to 1500 m). It is found in the North Pacific Ocean: Kuril Islands, Kamchatka, Alaska. The life period is 25-30 years.
There are two types: Alaskan and albacore, which despite unstable catching and small dimensions (up to 50 cm in length and 1.5 kg), is highly quoted on the Asian market (especially in Japan), thanks to the exclusive taste.
Grouper is usually red with small cheeks thorns, huge eyes, pulled up, which help to navigate at the sea bottom. The lower fin is divided into two lobes - the fish backs against the bottom and thus moves. But, in general, the fish is not quick: most often it lies and waits for a prey: shrimps, crabs, crustaceans, it suddenly attacks and then again falls in silt and sand.
It is interesting, that caviar is produced together with mucus, which forms a protective bubble that raises the 'kids' on the surface of the sea. To the naked eye to notice these bubbles is impossible.
The meat is juicy enough, but a bit harsh. It is rich in fatty acids, vitamins, minerals, contains a lot of fluoride and calcium, used in all cuisines of the world.
