Area of Expertise:
While Dr. Richard Beamish retired from DFO in 2011, he remains involved with the department as a scientist emeritus. Together with key staff, Chrys Neville, Ruston Sweeting and others, Dr. Beamish has been carrying out juvenile salmon surveys in the Strait of Georgia and Gulf Islands as part of a long term study of early marine life. Sampling is carried out in July, September and sometimes November. Work is carried out to examine marine survival, diet, residence patterns etc of the different salmon species.
Through collaboration with Kristi Miller and others, they are carrying out DNA analysis to improve understanding of the changes in the juvenile Chinook and sockeye salmon populations in the Strait of Georgia during their early marine life. This has provided information on important changes in the stock structure of both species between July and September.
Their analyses have indicated that Harrison River sockeye salmon appear in the Strait in July and are the dominant sockeye stock in the Strait of Georgia in September. This is important information as the Harrison River stock had increased marine survival in recent years whereas the marine survival of other (lake-type) Fraser River sockeye salmon stocks declined. To understand the mechanisms that may be regulating the marine survival of sockeye salmon in general, and this stock in particular, they are examining the marine distribution patterns to determine if there are specific rearing areas within the strait for various stocks or if the distribution between years varies.
