Description (abstract)

The importance of Arctic region is increasing progressively along the global climate change. The invasion of new fish species is especially evident in Arctic region, where temperatures have previously restricted cool and warm water species establishment.The general aim of project is to detect and quantify the impacts of new fish species invasion on ecosystem functioning and to provide the most suitable adaptation strategies to change in ecosystem services. The proposed multidisciplinary project combines several modern methods (stable isotopes, fatty acids, vitamin D, mercury) to achieve objectives. The key findings of the project will give direct knowledge how the invasion of non-native fish species will influence on the supply of essential fatty acids (omega-3 and 6) and vitamin D as well as exposure of toxic mercury. Results will give direct instructions which species should be preferred and which should be maximum consumption of fish in future. The project is financed by Academy of Finland during 2013-2017.
