Due to the mixed stock nature of the major ocean salmon fisheries and the limited data available on coho salmon, in the past, Thompson/upper Fraser River coho were managed and assessed (along with lower Fraser and Strait of Georgia coho stocks) as a large aggregate. In 1998, it was concluded that coho from the Thompson and upper Fraser River should be managed and assessed separately from other southern BC coho. This PSARC Working Paper is the first attempt to provide advice specific to Thompson and upper Fraser coho. Earlier assessments of southern BC coho identified concerns about the status of Thompson and other southern BC coho stocks. As a result, DFO implemented numerous fishery management measures designed to reduce coho exploitation rates. Despite these measures, spawning escapements to many Thompson streams continued to decline relative to their brood year escapement. The purpose of this report is to provide an assessment of the status of coho salmon from the Thompson/upper Fraser River. gccst Fisheries resources gccst Salt water fish gccst Fishing area gccst Fisheries management Irvine, James R.
