STS'AILES CHUM MARK RECAPTURE AND VISUAL STREAM ENUMERATION
JO Thomas has provided 25 years of continuous scientific support and analysis to the Sts'ailes and DFO for their Harrison River Chum mark-recapture and visual stream enumeration programs. The purpose of this study is to provide a robust technically and scientifically sound tagging and recovery program that estimates the annual chum spawning population in the Harrison and Chehalis Rivers, one of the largest and most important chum populations of the lower Fraser River.
CREEL SURVEY DESIGN AND IMPLEMENTATION
SELECTIVE FISHING RESEARCH
With growing interest in selective fishing practices since the early 1990s, JO Thomas has worked with government, industry, First Nations and recreational groups on a broad range of research projects aimed at developing practical, efficient methods to selectively harvest target salmon species without harm to incidental catch and release of vulnerable non-target species.
