Abstract: The addition of inorganic nutrients to increase fish production in the Mesilinka River, a northern interior river of British Columbia, is being investigated. Increased production of native stocks is desired to both offset negative impacts following the establishment of the Williston Reservoir and to meet increased angling demands for stream fisheries. 1997 was the fourth of four proposed years of fertilization of the Mesilinka mainstem. Three reaches on the Mesilinka River (an upstream control reach - Blackpine, and two downstream treatment reaches - T1 and T2) and an additional external reference system (the Nation River) were established in 1992 to monitor the effects of added nutrients on stream production. In 1997, inorganic fertilizer was added upstream of each of the two treatment reaches. Actual loading rates of nitrogen (N) and phosphorous (P) were ... Observations since fertilization commenced indicate that the two treatment reaches, T1 and T2, have responded differently to the addition of inorganic nutrients. Two hypotheses were first proposed after the second of the four fertilization years regarding the different responses of T1 and T2. A fish density response would be indicated ...
