Molecular Characterization of Novel Fish Viruses from Technical Assistance Cases

Viruses occur in many cultured and wild stocks of fish. William Batts collaborates with many government, state, tribal, and private research and diagnostic laboratories to aid in identification of these unknown replicating agents of uncertain pathogenicity. Typically, viruses can be replicated in a variety of fish cell lines and investigated at several temperatures to see if the cytopathic...

Non-lethal Detection of Skin Injuries in Juvenile Chinook Salmon Oncorhynchus tshawytscha by Fast Green FCF Dye

In fish, as in humans, an intact epidermis is critical to defense against entry of pathogens into the skin. Macroscopic examination of scale loss is the principal method of evaluating physical damage to juvenile salmonids out-migrating through hydroelectric dams in the Snake and Columbia Rivers, and in fish subjected to capture and handling procedures in locations such as hatcheries, fish...

Recovery of sockeye salmon in the Elwha River, Washington, after dam removal: Dependence of smolt production on the resumption of anadromy by landlocked kokanee

Pacific salmon Oncorhynchus spp. are adept at colonizing habitat that has been reopened to anadromous passage. Sockeye Salmon O. nerka are unique in that most populations require lakes to fulfill their life history. Thus, for Sockeye Salmon to colonize a system, projects like dam removals must provide access to lakes. However, if the lakes contain...
