Phylogenetic conservation units for rainbow trout in British Columbia by Megan R McCusker( Book )

3 editions published in 2000 in English and held by 15 WorldCat member libraries worldwide

This report summarizes the phylogenetic associations for British Columbia rainbow trout populations and makes recommendations for the conservation of this diversity. The summary is based on a recent study of DNA variation combined with older isozyme data, minisatellite data, and information on the geological history of the province. The study revealed distinct mitochondrial DNA lineages which overlap in their geographical range, and a comprehensive hypothesis on the origins of rainbow trout populations in British Columbia is presented which postulates a number of glacial refugia where trout survived the last glaciation
Application of the Large Lakes Kokanee Model to five management problems in British Columbia by Eric A Parkinson( Book )

An evaluation of adaptive management and minimal sampling as techniques for optimizing rainbow trout stocking rates by Eric A Parkinson( Book )

Sensitivity of British Columbia's freshwater fish to timber harvest : using species traits as predictors of species risk by Marc Stewart Porter( Book )

2 editions published in 2000 in English and held by 13 WorldCat member libraries worldwide

Assessment of fish response to perturbation can be based on a biologically integrated, mechanistic framework that examines the functional relationship between species and their environments. The overall effect of timber harvest on fish populations may then be predicted based on relative species tolerances to a range of potentially changing habitat conditions. This report evaluates seven major changes to stream & lake habitats associated with logging and identifies linkages to 12 associated functional traits displayed by 91 species or subspecies of fish found in British Columbia freshwaters. Fish taxa are then scored for trait sensitivities on the basis of information from the literature or expert opinion
Size selective predation by rainbow trout on two lacustrine Oncorhynchus nerka populations by Eric A Parkinson( Book )

Impaired school formation at low density : a mechanism for depensatory mortality in sockeye salmon by Eric A Parkinson( Book )

4 editions published between 1990 and 1992 in English and held by 12 WorldCat member libraries worldwide

During the lacustrine phase of their life history, sockeye salmon are planktivores that commonly school in the deeper, darker areas of the pelagic zone during the day, vertically migrate upward to feed at dusk, and then descend at dawn. Given a constant density of predators, the problem of school formation should be more severe at lower densities, since sockeye have more difficulty finding each other while encountering approximately the same number of predators. This paper uses a simple encounter model to illustrate the schooling problem and to provide some quantitative predictions to test the model. The schooling problem is also discussed in the context of the more general problem of compensatory predation and the role of predators in driving sockeye cycles and kokanee population fluctuations. The paper assumes that schooling confers an anti-predator benefit which reduces predation risk and that sockeye are unable to maintain schools at night rather than not choosing to do so
Macrohabitat use and predictive models of fish distribution in the Blackwater drainage by Marc Stewart Porter( Book )

2 editions published in 1998 in English and held by 11 WorldCat member libraries worldwide

The overall goal of the study reported was to quantitatively evaluate habitat use by fish in British Columbia, particularly non-game species whose habitat requirements are poorly understood, so as to assess which species might be most at risk from various land use practices. The study develops models of species richness, species assemblages, and individual species presence or absence as functions of a variety of macrohabitat variables in a high diversity watershed, the Blackwater drainage in the central interior. The main objective was to identify the physical variables that are important in driving community composition and discriminating between stream sites with and without particular fish species. Relationships were examined using a combination of map-based and field-collected data to determine the level of information necessary to reliably predict fish species distributions. Logistic regression models based on these variables were developed and the derived relationships were tested using independently collected data from the Blackwater drainage and from a distant watershed, the Similkameen drainage, to determine the utility of such models for management purposes
Long term data collection on kokanee from large lakes : does it make sense? by Eric A Parkinson( Book )

5 editions published in 1988 in English and held by 10 WorldCat member libraries worldwide

Report documenting the rationale and methodology for systematic data collection in the management of kokanee fisheries on large lakes. The report covers the rationale for collecting high quality data, choosing the data set, and costs and benefits. A description of the Kootenay and Okanagan data collection program is included
A morphological and electrophoretic comparison of rainbow trout (Salmo gairdneri) above and below barriers on five streams on Vancouver Island, B.C. by Eric A Parkinson( Book )

3 editions published between 1984 and 1985 in English and held by 10 WorldCat member libraries worldwide

Headwater areas of B.C. coastal streams, above barriers impassable to anadromous species, are generally inhabited by either rainbow trout or coastal cutthroat trout. It is important to know which form of rainbow is present above falls so that the appropriate set of regulations can be applied. In this study, the taxonomic status of trout in the headwater areas (above barriers) of 5 streams was determined morphologically and electrophoretically. Where rainbow trout were found, a second objective was to establish methods of differentiating between resident and anadromous forms
Identification of steelhead stocks in the commercial net fishery of the southern British Columbia coast by Eric A Parkinson( Book )

An evaluation of the catchable trout program in lakes near Vancouver, British Columbia by Eric A Parkinson( Book )

3 editions published in 1985 in English and held by 9 WorldCat member libraries worldwide

The success of a catchable trout program on seven lakes nearVancouver is described in terms of effort generated, successrates in the fishery and total catch

Food habits of Gerrard stock rainbow trout in Kootenay Lake, British Columbia by Harvey Andrusak( Book )

3 editions published in 1984 in English and held by 6 WorldCat member libraries worldwide

Kokanee and terrestrial insects were found to be the main fooditems of the Gerrard stock of rainbow trout. Mysis were not amajor food item. Conspicuously absent were other typical rainbowfood items such as benthic invertebrates and zooplankton.Kokanee as a diet item increased in importance in the winter andwith increasing rainbow size. The construction of the DuncanDam, which destroyed a major kokanee spawning area, had nonoticeable effect on the diet of these fish
