Infection of whitefish ( Coregonus lavaretus L. s.l.) by Triaenophorus crassus Forel (Cestoda: Pseudophyllidea): a case study in parasite control
A case study of Triaenophorus crassus control in two sympatric whitefish populations was carried out in Stuorajavri, northern Norway. The densities of whitefish and pike were markedly reduced by an intensive fishing programme and during the 6 years of investigation, a dramatic decline in T. crassus...
