A Review of the Occurrence of Pacific Salmon (<i>Oncorhynchus</i> spp.) in the Canadian Western Arctic

Аннотация

This manuscript summarizes all known captures of Pacific salmon (Oncorhynchus spp.) in the Canadian western Arctic up to the end of 2003. Historic information on Pacific salmon distribution in the Canadian western Arctic is limited, and some older identifications are suspect. It is difficult to determine whether salmon numbers are actually increasing, or whether a recently established program to gather information on Pacific salmon abundance has only made them appear more abundant than historically. However, there is no evidence of newly established populations and overall not enough information to state definitively that salmon are increasing in frequency in the Canadian western Arctic as a direct result of climate change.
