 |Project summary=The Ingarskilanjoki River is 50 km long and runs into the Gulf of Finland. The Ingarskilanjoki River is the only river in Finland where the population of extremely endangered migrating sea trout (Salmo trutta) is natural, not from stocking. Due to flooding of the fields the river was straightened and dredged in 1988. The river was restored in 2002-2007 to recreate habitats for trout and its reproduction for the whole river length. The goal of the restoration was to increase the morphological diversity of the river by e.g. creating more variation of depths and meanders and adding gravel for fish spawning. The goal was also to enable the trout to migrate between the river and sea. In addition buffer strips were created to the catchment to decrease the nutrient loading from arable areas and to decrease turbidity of the river water. The local land owners and river side inhabitants were interviewed in order to take into account their opinions due to restoration. To ensure the recovery of the natural sea trout population, the trout fishing was prohibited in the river after the restoration. Before the dredging of the river, natural trout were caught and raised for further farming. After the dredging, the trouts that were caught  from the natural population were stocked back into the river. However, because of the clearing and lost habitats, the reproduction of the trout had been weakened. The key success factor was that the decision of the preservation was made by the local fishing society. This is most likely the reason for that the fishing restriction has been obeyed which again has been crucial for  balancing the reproduction and population of the sea trout. Since strict fishing restrictions, restorations and additional fish stockings, the local trout population has grown. These results shows that the restoration as a whole was succeeded.
