Habitat modifications from coastal development in a Baltic Sea archipelago - Impact on fish, primarily on eurasian perch (Perca fluviatilis)

We have compared 16 years of fish catch data, primarily for perch (Perca fluviatilis) from two archipelago areas in the Baltic Sea, one strongly impacted by coastal development and the other a reference area. Comparisons were also done with five years of data from a third area, where the coastline is only modestly modified. In addition, data from a smaller study is included, in which one of the three areas is extremely impacted and probably without any natural shores left. There were no general differences in catches of perch between heavily developed and the much less impacted areas.
