ABSTRACT: Throughout their circumpolar range, species within the coregonid complex are ecologically and socioeconomically important and are heavily impacted by human activities. In the Laurentian Great Lakes, abundance and diversity of ciscoes is well below historic levels. The species complex has generally been preserved in Lake Superior, Lakes Huron and Michigan still contain at least one deepwater cisco form and one pelagic form, Lake Ontario only contains pelagic form, and ciscoes have been extirpated from Lake Erie. Accurate identification of forms is critical for the development of effective restoration and management plans. Currently, form classifications are based on morphometric variation. However, the relative influence of phenotypic plasticity and heritable genetic differences in determining these forms is not well understood. The overall goal of this research is to construct sex-specific linkage maps using data from thousands of genetic markers genotyped in haploid and diploid families produced from cisco collected in northern Lake Huron. The linkage map will be used as a genetic resource that will facilitate research with the aim of determining the degree of heritable genetic differences among cisco forms.
