Over the past 30 years, the food sources that most fish species in the northern Baltic Sea rely on — phytoplankton and zooplankton — have diminished greatly, according to new research from the Finnish Environment Institute.<\/p>\n

Overall, the nutrition available to the ecosystem as a whole has greatly lessened. “The amount of energy available for planktivorous organisms has declined after the late 1970s, as both the food quality of phytoplankton and the mean size of zooplankton have decreased,” says senior researcher Sanna Suikkanen from Marine Research Centre at the Finnish Environment Institute.<\/p>\n

“The observed change is probably due to complex interactions between climate warming, eutrophication and overfishing.”<\/p>\n
