hyperglyph fish

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.
