A genetic linkage map of anonymous and gene-linked microsatellites was generated for red drum, an economically important sciaenid fish cultured for both restoration enhancement and commercial food-fish production. The consensus map, based on linkage data combined from two full-sib families, consisted of 486 total microsatellites (440 anonymous, 46 gene-linked), and spanned 24 linkage groups corresponding to the 24 (haploid) red drum chromosomes. The linkage map generated was used to identify regions of shared synteny between red drum and four other percomorph species for which genome assemblies are available. Considerable synteny was observed between red drum and all four comparison species, and a synteny-based mapping approach was used to putatively localize an additional 80 genes and monomorphic, gene-linked microsatellites within the red drum genome. The genetic linkage map will be a valuable resource for red drum aquaculture, particularly for candidate-gene approaches to identify and map quantitative trait loci.
