Abstract

We evaluated how cyanobacteria bloom, driven by agricultural eutrophication (defined as an increase in nutrients) or global warming, influence fatty acid profiles of phytoplankton, zooplankton (Daphnia + Bosmina), and fish (roach and perch) in eutrophic Lake Köyliöjärvi and mesotrophic Lake Pyhäjärvi. Regarding the nutritional value of food web components, we evaluated changes in the ω-3 and ω-6 polyunsaturated fatty acids (PUFA) of phytoplankton and consumers at different trophic levels. We report the fatty acid results as percentages (%) and content (µg FA mg-1 C-1).
