"Spring and summer spawning species such as perch, carp and pike will benefit from rising temperatures, while autumn spawning such as salmonids may be disadvantaged," they write in the Baltic Sea Climate Change Fact Sheet report.
The report has been produced by Helcom in collaboration with Baltic Earth.
The Baltic Sea Center at Stockholm University has also contributed to the research.
The idea is that this report will be updated every seven years.
Hot water
According to the researchers, the effects of climate change can already be seen today in the Baltic Sea.
The water temperature has risen more than in the larger oceans in the last 100 years.
The water temperature is also expected to rise between 1.2 and 3.2 degrees by the year 2100, depending on how the emissions develop.
A decisive factor for the eutrophication situation is how well the countries around the inland sea succeed in limiting the supply of nutrients from land, the researchers state.
