The fry stay in the upper layers longer than cod and haddock, and can often be observed hiding under the lion’s mane jellyfish. The whiting matures when it is 2 years old.
The whiting is one of the most important predators in the North Sea.
The main prey is Norway pout, sandeels and herring, but it also eats fry of cod, haddock and its own kin. The whiting is mostly found near the bottom at 10-200 m depth, but it may also rise from the bottom up into the free water layers.
