Identifikasjonstips

1. 1

   Lateral Line

   The most reliable distinguishing feature is the dark, distinctly arched lateral line, which curves sharply upwards over the pectoral fin. This contrasts with the straight lateral line of Saithe (Pollachius virens).

2. 2

   Chin Barbel

   Pollack lacks a chin barbel, a small fleshy appendage found on the chin of many other gadids like Cod (Gadus morhua) and Haddock (Melanogrammus aeglefinus).

3. 3

   Lower Jaw

   The lower jaw protrudes beyond the upper jaw, giving it a slightly underslung appearance.

4. 4

   Coloration

   Generally darker, more greenish-brown dorsally compared to the Saithe, which is typically darker and more uniformly colored.
