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?
