wfrc.usgs.gov — This study will compare relative abundance, population structure, and spawning success of desert pupfish from natural (reference) and manmade or disturbed habitats in the Salton Sea basin. In addition, this study will determine the importance of fish predation as a source of mortality in desert pupfish populations. Finally, this study will attempt More...

wfrc.usgs.gov — As anadromous juvenile salmonids migrate from freshwater rearing habitats to the ocean, they are vulnerable to a host of factors that affect their survival. Direct effects associated with dam passage (e.g., instantaneous mortality, injury, loss of equilibrium, etc.) and indirect effects (e.g., predation, disease, and physiological stress) More...

wfrc.usgs.gov — Bacterial kidney disease (BKD) is caused by Renibacterium salmoninarum and is considered to be the most difficult salmonid bacterial disease to control, in part because of its dual modes of transmission. This bacterium, unlike most other fish pathogens, is transmitted vertically from parent fish to progeny in association with the eggs, as well as 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...
