  • Pollock Sizes

    Pollock is a common name that is used to refer to two different species of fish from the same genus. If you check either an American or a British dictionary you can find the name spelled either as pollack or pollock. Either way, it still refers to the same type of fish. People sometimes ask about pollock sizes, habitats, and other general characteristics of this quite popular game fish.

    People sometimes do not distinguish between these types of fish even though there are definitely distinguishing features from each specie. Anglers just refer to them as pollock simply because of how these fish look like and how they fight back when caught using a hook and line.

    Fishes in the Name

    There are actually many different names for the two species of fish that people simply label as ‘pollock’. As stated earlier, the different species that are tagged as such belong to the same genus – Pollachius. They belong to either of two species, first is P. pollachius and the second is P. virens. There are different lay men names that people give to these species.

    Common names for P. virens include saithe, coalfish, silver bills, and Boston blues. People sometimes call P. pollachius as European pollock, lieu jaune, Atlantic pollock, and lythe. Any of these names fall under one general label when you ask around, and that is pollock. It is a type of fish that is popular among sports fishermen and on the table.
