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, 1,506 post-spawn pink salmon carcasses from hatchery activities were re-distributed in upper reaches to provide a direct food source to juvenile steelhead, coho, and trout. Salmon carcasses were pitched directly into the stream and allowed to drift downstream during high flows. The pollock bone meal product was transported in burlap bags (10 kg/bag) and anchored to the stream bottom using large cobbles. Effectiveness monitoring over the treatment period 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 with pollock bone meal. BC Conservation Foundation (BCCF), Kwakiutl First Nation (KFN) and the Northern Vancouver Island Salmonid Enhancement Association (NVISEA) were involved with fertilizer applications, carcass distributions and effectiveness monitoring.
