USGS Ecosystems Fisheries: Aquatic and Endangered Resources Program Research  Genetics, Genomics, and Molecular Biology

Genetics, Genomics, and Molecular Biology

Research on genetics and genomics of fish and other aquatic organisms examines and characterizes variation, diversity, taxonomy, and the response to environmental change of individuals, stocks, strains, and populations. This capacity allows aquatic resource managers a more accurate method to identify and discriminate among native, cultured, introduced, and invasive aquatic species, as well as develop science-based conservation and restoration strategies. USGS research applies molecular tools to fisheries resource issues including: construction of genomic libraries, cloning, sequencing, phylogenetic analysis, recombinant DNA expression systems, standard and quantitative polymerase chain reaction assays, random-amplified polymorphic DNA fingerprinting, DNA probes, and DNA microarray.
