Abstract:

The objective of this study was to develop a method of sampling the intestinal tract of non-feeding adult chinook salmon Oncorhynchus tshawytscha for the myxosporidan parasite Ceratomyxa shasta without sacrificing the fish.  Chinook salmon in the Pacific Northwest is a diminishing resource; therefore, valuable Columbia River stocks used in this research could not be sacrificed because they were required to meet hatchery production goals.  Since the parasite is present in the descending intestine late in the course of the disease, an intestinal lavage technique was developed.  When compared with the conventional sampling method, the lavage proved effective with no apparent adverse affects.
