The hyperglyph fish belongs to the Perch-like order from the Centrolophidae family. There are 6 types in total. The most common of them are Japanese, southern, Antarctic and Atlantic. And if the last of the species lives in the Atlantic Ocean, then the range of the first is the temperate and subtropical waters of the northwestern Pacific Ocean. This hyperglyph is common along the coast of Japan and the southern Kuril Islands. It is also found in the waters of the Sea of Japan, from Tsushima Island to southern Sakhalin and from Busan to northern Primorye.

Hyperoglyph is a fish with a relatively tall bluish or greenish-gray color with reddish-brown hues. Moreover, the abdomen and sides are lighter, and the back with the head is darker. Gill covers with silvery overflow. Juveniles may differ in not very pronounced striped coloration. The Japanese hyperglyph has a rather large head, which makes up at least 30% of the entire body, it is naked with a blunt and short snout. The eyes are of medium size with a golden iris. The jaws are equipped with single-row, sharp, frequent and small teeth. The dorsal fin is solid, the pectorals are rounded and relatively small, and inyoung growth pointed. But the ventral fins are poorly developed. The lateral line begins above the gill cover. It, smoothly curving, continues behind the end of the pectoral fins and goes in the middle of the side to the end of the anal. Body length can reach 90 cm, and weight - 10 kg, most often there are individuals no more than 40-60 cm.

Few people know what a hyperglyph fish looks like, since not everyone knows about it, and its biology has been little studied by scientists. Adult individuals live near the bottom at fairly large depths (from 100 to 450 m). They feed on bottom small fish, their juveniles, as well as tunicates, cephalopods and all kinds of crustaceans. Almost nothing is known about their reproduction. Presumably, the hyperglyph fish spawns in late autumn. Its juveniles prefer to be closer to the shore or in the pelagic zone. In other words, in the water column between the bottom and the surface. They try to stay under drifting algae or any floating objects. Off the coast of Canada in the waters of the Atlantic, they can be found from June to October.

In general, hyperglyph fish has no independent commercial value. In the North Atlantic, it is rather a by-catch object in coastal waters, where it is caught by water trawls. But in Japan and Chile it is a commercial fish. Off the coasts of these countries, it forms shoals above the continental shelf in the bottom layers and in the pelagial of the open sea. It is especially valued in the land of the Rising Sun and is used as a table fish. Boiled her meatvery tasty and juicy, and the broth has a wonderful aroma. It is also good in cold and hot smoking with fillets.

In Russia, the hyperglyph is also caught as by-catch, no more than 10-12 tons per year. And in the summer-autumn period (during migrations) it becomes an object of sport and recreational fishing. They catch him on spinning in the area of Furugelm Island or the Rimsky-Korsakov Islands, which are located in Peter the Great Bay.
