In this report, we review the extent of knowledge of biodiversity in British Columbia Oncorhynchus mykiss. We review hypotheses of subspecies designations for rainbow trout as well as detail the range of studies describing differentiation among populations in phenotypic and biochemical/molecular characters. A summary of populations of special concern by management region is also presented. We also propose a two-stage biodiversity research plan to (i) resolve the major phylogenetic groups of rainbow trout in the province that should form the highest priority for conservation, and (ii) provide a description of the organization of molecular genetic variation as well as an inventory of the adaptive ecotypes of rainbow trout within each of eight proposed "aquatic ecoregions" in British Columbia. We propose a general methodology where differentiation in molecular genetic and adaptive traits can be utilized in a complementary fashion to set conservation priorities for individual populations of rainbow trout.
