The chemical composition of the muscle of cod varies according
to the different localities.
First we have a very definite difference in the chromatographic
pattern of cod-muscle between cod from the southern waters (Skagerrack)
and those from northern waters (Lofoten area). This difference
occurred in all specimens examined, irrespective of local varieties.
Secondly, the cod from the two localities can be separated in
sub-groups.
Cod from the Skagerack:
1. Littoral cod.
2. Deep-sea cod from the Norwegian "skjærgård".
3. Cod from the open Skagerack.
Cod from the Lofoten area:
a. Coastal cod (resembles Skagerack-group 1).
b. Deep-sea cod (resembles Skagerack-group 2).
c. Common skrei (resembles Skagerack-group 3).
d. Type not characteristic. Bank cod? or Murm. cod. (This
type has till now not been observed in the Skagerack).
Finally the cod muscle has been hydrolysed, and the different constituents
building the complex molecules or the amino-acid-group
containing part of the muscle are identified.
