Fatty acid composition and content of round goby (Neogobius melanostomus Pallas 1814) and monkey goby (Neogobius fluviatilis Pallas 1814), two invasive gobiid species in the lower Rhine River (Germany)

Here we hypothesize that, due to their brackish water origin, monkey goby and round goby in the River Rhine might have a higher content of long-chained PUFAs and a higher n-3/n-6 ratio than native species. We therefore analysed the fatty acid profiles of monkey goby and round goby caught at Lower Rhine. Data for roach, bream, and perch, obtained from an extensive analysis of 56 samples.
