The directive of Fisheries and Oceans is to achieve a net gain of habitat for Canada's fisheries resource. DeMamiel Creek has decreased Coho salmon productivity due to a high fry to smolt mortality. Enhancement of rearing habitat has resulted in a 7.2% increase in returning spawners. This confirms the theory that Coho salmon production in DeMamiel Creek is limited by fry to smolt survival. When the number of smolts is known the resulting adult returns can be predicted several years in advance since 6.37% of smolts return as adults to spawn. Continued enhancement efforts should yield increasing returns of fish.
