ABSTRACT

The taxonomic status of cod from the Baltic Sea has not yet been fully recognized. The aim of this study was to determine the suitability of regular SDS-PAGE electrophoresis to differentiate between two cod sub-species from the Baltic Sea. The examined fishing grounds were the Barents Sea (the region of Bear Isle), the Strait of Sund and Puck Bay (Baltic Sea). In muscle extracts from individuals from the Barents Sea and the Strait of Sund, SDS-PAGE analyses showed protein profile consisting of 25 proteins compare to 16 proteins from cod from the Baltic Sea. Fourteen of them were common for both groups. The results obtained in this study show that cod from the Strait of Sund show a high similarity (and are in fact identical) to cod from the Barents Sea. SDS-PAGE protein profiles of proteins from the Baltic Sea cod are different from cod from the Barents Sea and the Strait of Sund. Therefore it may be a strong premise for the statement that G. morhua callarias is a local Baltic subspecies.

Key words: Atlantic cod, Baltic cod, Gadus morhua, polymorphism, skeletal muscle protein.
