| 摘要： | The Archipelago Sea between Sweden and Finland is an unique environment with a high ecological value. It forms an excellent area for a large variety of sea birds and fish. The shallow waters, underwater rocks and embankments make it suitable for the good fish reproduction too. One of the most important reproduction area of the fish stocks is located just near the dense populated area, off the Port of Turku. During the recent years, however, the eutrofication and the increased anthropogenic impact has caused an increased decline of the fish stocks: old spawning sites have been siltated, vegetation changes have been taken place, and a large amount of fish eggs have been washed out. This paper describes the field experiments and studies conducted in the Archipelago Sea to learn more on the parameters affecting to the siltation phenomenon. The impacts of the passing ships were studied by flow and wave measurements supported with sampling. The nearby dredging and reclamation activities are also analysed and discussed. |
