Since it seems to be in Swedish or German, it's a safe bet that the Super predator is a pike. Musky are native only to North America (East of the Rockies) and haven't been widely transplanted elsewhere. Many Pike don't have the classic chain-link look especially when they come from Eutrophic (fertile, shallow, sand/mud bottomed w/ med-low clarity)lakes, which the water shown looked like.
Tight lines,
