fl.biology.usgs.gov — The Nile tilapia (Oreochromis niloticus) is commonly used in aquaculture worldwide. Feral populations exist in many regions where individuals escape culture and establish in natural habitats. In Mississippi, Nile tilapia are established in at least three distinct localities (fig. 1): the lower Pascagoula and Escatawpa river drainages, and a More...

fisc.er.usgs.gov — This website provides access to the list of imperiled freshwater and diadromous fishes of North America as determined by the 2008 American Fisheries Society (AFS) Endangered Species Committee (ESC) on Fishes. At this website, one can view lists of imperiled fishes by freshwater ecoregion, by state or province boundary, and plot distributions of More...

www.usgs.gov — Nearly 40 percent of fish species in North American streams, rivers and lakes are now in jeopardy, according to the most detailed evaluation of the conservation status of freshwater fishes in the last 20 years. The 700 fishes now listed represent a staggering 92 percent increase over the 364 listed as "imperiled" in the previous 1989 study More...

www.lsc.usgs.gov — Molecular genetics has recently achieved an important place in contemporary conservation biology as it has proven to be a robust tool for identifying reproductive isolation among populations, permitting the delineation of management units (MUs) and allowing assessment of conservation priorities from an evolutionary perspective (i.e., More...

www.absc.usgs.gov — Genetics of Alaska Fishes Projects studies include comparing molecular genetics for rainbow trout throughout their range in Alaska and use microsatellite analyses to look at hatchery and wild populations of steelhead in the Snake River (Phylogeographic analysis of rainbow trout in Alaska). Research also looks at genetic population structure of More...
