Local fishing closure improved European eel stock on the Swedish west coast
The number of eels leaving the Swedish west coast to spawn in the Sargasso Sea has increased since eel fishing was closed in 2012. This is shown in a new study from the Swedish University of Agricultural Sciences (SLU), which for the first time evaluates the effects of the closure. -
Positive signals and alarming trends in new fish reports from a unique environmental monitoring program
Since the 80s, The Swedish University of Agricultural Sciences (SLU), the University of Gothenburg and the Swedish Museum of Natural History have monitored fish health, population status and contaminant levels in fish along the Swedish coast. Results from four reference areas have now been released. -
Researchers' call: Consider the risk of animal-borne diseases in ecosystem restoration
Disturbances in the habitats of wild animals increase the risk for outbreaks of animal-borne diseases. However, even when habitats are restored, there are risks that should be taken into account. This according to a study led by researchers at the Swedish University of Agricultural Sciences (SLU). -
More hands in the water to give researchers better insight into Baltic Sea fish
Can more hands in the water provide better knowledge about fish health? Researchers from the Swedish University of Agricultural Sciences (SLU) are now testing a new method to collect data along the Swedish Baltic Sea coast. -
SLU’s first eel survey in the Nyköpingsån aims to provide knowledge about the eel’s future
Hydropower plants and dams pose major obstacles for the critically endangered European eel. Now researchers from the Swedish University of Agricultural Sciences (SLU) want to find out how eels in the Nyköpingsån are affected if the water is allowed to flow more freely. -
The noble crayfish in danger – new animated film aims to inspire action
The situation for the noble crayfish, our only native freshwater crayfish species, is critical. The species has disappeared from large parts of Sweden and Finland. Now, a new animated film aims to engage a new generation through a story that blends loss with hope for the future. -
Climate changes threatens Lake Mälaren's ecosystem
Lake Mälaren’s environmental condition continues to concern researchers. The Focus on Mälaren 2024 report shows that the lake’s surface water temperature continues to increase, which makes it harder to combat eutrophication. -
Forage availability and local adaptation are keys to successful game management
In areas previously dominated by moose and roe deer, there is now also fallow deer, red deer and wild boar. More species increases competition for food, which in the long run may increase browsing damage to pine... -
Red flag for food webs in the Bothnian Sea
