Wadden Sea fish stocks shrink due to warmer seas, coastal works
Fish stocks in the Wadden Sea have been shrinking steadily since the 1980s because their natural habitat is deteriorating, according to a new report.
The report, drawn up by government scientists and other researchers, says climate change, fishing, sand extraction and dyke building have all contributed to the lack of good areas for fish.
The changing sea environment has hit fish such as cod, plaice and dab which spend their early years in the tidal waters. Stocks of fish which live in estuaries and do not migrate are unaffected and some populations have even increased, the report says.
The Wadden Sea, which is extremely shallow, is warming up quickly and this is also having an impact on fish stocks.
