Fish & Wildlife Disease: Wild Fish Diseases
Active
By Biological Threats and Invasive Species Research Program
September 29, 2022
USGS fish disease research is focused on developing advanced tools for rapid disease detection and control. USGS scientists are improving our understanding of the factors controlling the epidemiology of aquatic animal diseases and the impact of disease on wild fish populations. Our scientists are also investigating the effects of warming waters, drought, and invasive species on fish disease dynamics.

Phylogeographic genetic diversity in the white sucker hepatitis B Virus across the Great Lakes Region and Alberta, Canada Phylogeographic genetic diversity in the white sucker hepatitis B Virus across the Great Lakes Region and Alberta, Canada
Hepatitis B viruses belong to a family of circular, double-stranded DNA viruses that infect a range of organisms, with host responses that vary from mild infection to chronic infection and cancer. The white sucker hepatitis B virus (WSHBV) was first described in the white sucker (Catostomus commersonii), a freshwater teleost, and belongs to the genus Parahepadnavirus. At present, the...

Development of a suite of functional immune assays and initial assessment of their utility in wild smallmouth bass health assessments Development of a suite of functional immune assays and initial assessment of their utility in wild smallmouth bass health assessments
Methods were developed for measuring immune function in Micropterus dolomieu (smallmouth bass). The ultimate objective is to monitor and evaluate changes over time in immune status and disease resistance in conjunction with other characteristics of fish health and environmental stressors. To test these methods for utility in ecotoxicological studies, 192 smallmouth bass, age 2 years and...

Pacific herring Clupea pallasii are not susceptible to vibriosis from Vibrio anguillarum or V. ordalii under laboratory conditions Pacific herring Clupea pallasii are not susceptible to vibriosis from Vibrio anguillarum or V. ordalii under laboratory conditions
The ubiquity of Vibrio spp. throughout the coastal marine waters of the Pacific Northwest of North America raises questions about the susceptibility of native marine fishes, including Pacific herring (Clupea pallasii). Early reports of Vibriolike disease (Rucker et al., 1954; Walford, 1958) and Vibrio sp. isolations (Pacha & Kiehn, 1969) in Pacific herring remain questionable because...

Comparison of anadromous and landlocked Atlantic salmon genomes reveals signatures of parallel and relaxed selection across the northern hemisphere Comparison of anadromous and landlocked Atlantic salmon genomes reveals signatures of parallel and relaxed selection across the northern hemisphere
Most Atlantic salmon (Salmo salar L.) populations follow an anadromous life cycle, spending early life in freshwater, migrating to the sea for feeding and returning to rivers to spawn. At the end of the last ice age ~10,000 years ago, several populations of Atlantic salmon became landlocked. Comparing their genomes to their anadromous counterparts can help identify genetic variation...

Mass mortality in freshwater mussels (Actinonaias pectorosa) in the Clinch River, USA, linked to a novel densovirus Mass mortality in freshwater mussels (Actinonaias pectorosa) in the Clinch River, USA, linked to a novel densovirus
Freshwater mussels (order Unionida) are among the world’s most biodiverse but imperiled taxa. Recent unionid mass mortality events around the world threaten ecosystem services such as water filtration, nutrient cycling, habitat stabilization, and food web enhancement, but causes have remained elusive. To examine potential infectious causes of these declines, we studied mussels in Clinch...

A fishery after the decline: The Susquehanna River Smallmouth Bass story A fishery after the decline: The Susquehanna River Smallmouth Bass story
The Smallmouth Bass Micropterus dolomieu fishery in the Susquehanna River basin, Pennsylvania, is one of the most socioeconomically important fisheries in the region and has recently undergone considerable changes. These changes started in 2005, when disease was documented in young-of-the-year (age-0) Smallmouth Bass. Shortly thereafter, declines in abundance of both juveniles and adults...
