Kootenay Lake Nutrient Restoration Program North Arm and South Arm
Author: M. Bassett, E.U. Schindler, R. Fox, D. Johner, T. Weir, L. Vidmanic, K.I. Ashley, K. Peck
The overall objective of the nutrient restoration program is to promote primary productivity by additions of nutrients. The result of higher productivity is efficient transfer of nutrients up the food web from zooplankton to kokanee. Kokanee are the primary food source for two apex piscivores in Kootenay Lake: Gerrard rainbow trout and bull trout. One of the Kootenay Lake fish priorities as laid out in the FWCP Large Lakes Action plan is: Province of BCs highest sport fishery priority is the Gerrard rainbow trout, followed by bull trout, and there is a desire to increase the in-lake population of large fish to support a world class recreational fishery. FWCP, 2012). Further objectives of large lakes management as discussed in the FWCP large lakes action plan is to: 1. Conservation Ensure a productive and diverse aquatic ecosystem, 2. Conservation Improve the status of species of conservation concern, and 3. Sustainable Use Maintain or improve opportunities for sustainable use (FWCP, 2012).
