Pollock bone meal was applied to the Cluxewe River and monitored for its effectiveness as a nutrient source for stream enrichment. A total of 1,280 kg of fertilizer was applied in the spring to boost primary production through the summer growing season. In the fall 1,102 post-spawn pink salmon carcasses from Quatse River Hatchery were distributed to provide a direct food source to juvenile steelhead, coho, and trout. The pollock bone meal product was distributed in 10 kg burlap bags and placed on the stream bottom beneath large cobbles. Pink salmon carcasses were pitched directly into the stream and allowed to drift downstream during high flows. Effectiveness monitoring in the summer included water chemistry analysis for low-level nutrient concentrations and visual observations in treated and control reaches. Increased algae abundance was evident in sites treated in the spring with pollock bone meal. BC Conservation Foundation, Kwakiutl First Nation and the Northern Vancouver Island Salmonid Enhancement Association were involved with fertilizer applications, carcass distributions and effectiveness monitoring.
