Herring 

Herring, just like sardine, sprat and anchovy, belongs to the herring family. It belongs to schooling fishes that live not only in the Baltic and North Sea, but also in the entire North Atlantic Ocean from Norway to Greenland and North Carolina.

The fish reaches up to 40 centimeters in length, while some individuals live to 20 years. The shoals of herring can be seen in the open sea with the naked eye, since the surface of the body of the fish is very bright. Under water, the herring back is reflected in colors ranging from yellowish green to blue-black and blue-green. Boca fish have a silver color, rolling down to white.

Herring feeds on zooplankton and often becomes prey to other marine animals. Deprived of the aquatic environment, this fish loses its luster and, acquiring an ordinary blue-green color, becomes rather unremarkable. Herring features are thornless scales, smooth gill covers and lower jaw, exceeding the upper jaw size. The ventral fin of the herring is under the dorsal beginning. In the period from the beginning of March to the end of April, the herring becomes especially fat and tasty, since spawning occurs at this time, when millions of individuals go to the harbors and estuaries for throwing caviar.
