摘要：

Densities of whitefish and pike Esox lucius were markedly reduced by an intensive fishing programme and during the 6 yr of investigation, a dramatic decline in T. crassus infection of whitefish was observed. The mechanisms involved in parasite control were elucidated by studying the differences in infestation over time between T. crassus and a related cestode, Diphyllobothrium ditremum, in the 2 whitefish populations. Reduction in population density of the final host, pike, is suggested as being the key factor in control of T. crassus. -from Authors
