Jean-Marc visited during the summers of 2003 and 2004, to continue collaborations with CRI established during his postdoctoral fellowship. He provided technical assistance to graduate students and researchers working with passive integrated transponder (PIT) technology, and continued his collaborative salmon research with Dr. Cunjak and other CRI personnel.

Stuart Bunn came to Canada for several months in 2002 and 2005, to further the development of the river hydraulics and habitat field course. His expertise in stable isotope analysis and riverine production was an invaluable contribution to the students and scientists at the CRI.
Life histories and feeding ecology of salmonid fishes and aquatic invertebrates.
Dr. Doucett used stable-isotope analysis (SIA) to understand the life history and feeding ecology of salmonid fishes and aquatic invertebrates. Specific project objectives included: establishing diet-tissue isotopic fractionation and turnover times in juvenile salmon, assessing the relative importance of egg-predation to the diet of precocious parr and identifying anadromy in adult brook trout and their young-of-the-year progeny. Phoresy and parasitism were distinguished in commensal chironomids using SIA. In addition, the utility of SIA to differentiate between aquaculture escapees and wild Atlantic salmon was determined.
