Methods and summary data for limnology and food web structure in Skaha Lake, B.C. (2005-2013), revised / K.D. Hyatt ... [et al.]. : Fs97-13/1275E-PDF

"Here we provide a detailed site-description and report on field survey and sample processing methods used on Skaha Lake to assess annual to seasonal changes in: (1) limnological conditions (temperature, oxygen, water transparency, nutrient concentrations, plankton abundance and production etc.), (2) abundance and biological traits of juvenile Sockeye and kokanee salmon, and (3) abundance and biological traits of other limnetic fish species. Monthly or sub-monthly survey work was especially intensive during the years 2005-2013. The first objective of this nine year program was to compare rates of growth and rates of egg-to-smolt survival from hatchery-reared Sockeye, stocked into Skaha Lake, with similar rates from the wild Osoyoos Lake population, which contributed the eggs used in the hatchery program. A second objective was to investigate the possibility that stocked age-0 Sockeye might in some way, have negative impacts on resident kokanee in Skaha Lake. The report that follows provides a formal summary of the fisheries and limnology methods and data gathered at Skaha Lake in association with experimental introductions of Sockeye Salmon fry during years 2005-2013"--Abstract, p. v.
