Distribution of Cryptobia salmositica , a haemoflagellate of fishes, in British Columbia and the seasonal pattern of infection in a coastal river
A survey of adult Pacific salmon (Oncorhynchus spp.) from 1981 to 1983, along with other observations, demonstrated that in British Columbia Cryptobia salmositica was confined to tributaries of the Fraser River, coastal rivers adjacent to this river, and rivers on Vancouver Island. Adult salmon from...
