Biotic, chemistry and hydromorphologic studies were carried before restoration in order to select suitable sites by evaluating the viability and the size of the population:
 
  
 
1. BOTIC: Monitoring freshwater pearl mussel and host fish. Electricfishing were carried to evaluate the host fish population (and to assess mussel larvae parasites on fish geals) and mussels inventories were done by using an Aquascope or peep box (monitoring according to the standard method recommended by the Swedish Environmental Protection Agency)
