High diversity of fish in the newly created Fyleån Creek

In total five fish species were caught by electro fishing in Fyleån Creek. These parts of Fyleån Creek were re-created during 2013 by re meandering measures. The species caught were brown trout, three spined stickleback, bullhead, minnow and European eal. Clear evidence of spawning activities by brown trout was also noted. Interestingly, four of the species (eal excluded) are identified as potential hosts species for the thick shelled river mussel during its parasitic stage. The ecological response post restoration is fast and strong, in a positive direction indeed.

The highest diversity, and most individuals caught, were at sites with high habitat variability (gravel, stones, woody debris and vegetation), whereas sites with homogenous habitats (sand and fine organic matter) corresponded to low diversity and few individuals caught.

Bank erosion expose high abundances of woody debris. Something to bear in mind while discussing how to increase the habitat variability in Fyleån Creek during future discussions?


Vindelriver Life final conference

Written by Ivan on . Posted in Communication

The Vindelriver-life gang held their final conferance in Lycksele. It was quite a success, – with over 100 participants from approximately 10 different contries… We salute the orginazers for a super-well orginized and interesting event

Our project was represented by Martin, Andreas and I giving a oral presentation “Bening river by mussels” and a role-up describing our progress so far

5000 juveniles on its way

Written by Ivan on . Posted in BOB'S BLOG, Re-introduction of Unio crassus, River Fyleån

Following successful farming methods in our laboratory at Hemmestorp, approximately 5000 Unio crassus (thick shelled river mussels) juveniles are ready to go! The mussels will be transported and introduced into the recently restored Fyleån Creek the following days

At the same time, professional advises regarding project management issues were given by Inga Rasinca, our LIFE-monitor. Following the two-day reviewing process, our project was given top marks, – isn’t that so Inga?
