Diseases of Aquatic Organisms

A multi-agency effort assesses the health of manatees and provides baseline information on their health, reproductive status, and nutritional condition.

USGS is studying the spread and effects of “blotchy bass syndrome” on black basses ( Micropterus spp). USGS and state agencies have partnered with citizen scientists and recreational organizations to create a continent-wide biosurveillance network to monitor the syndrome.

Corals reefs support marine biodiversity, protect coastlines from storm surges and strong waves, and provide income from tourism to coastal communities. Coral diseases were first recognized in the 1970s and are now considered a major threat to coral reef survival worldwide. Stony coral tissue loss disease (SCTLD) emerged in Florida in 2014, impacting coral reefs in Florida, Puerto Rico, US Virgin...

The Aquatic Disease and Pathogen Repository (AquaDePTH) will be a public-facing national repository to support biosurveillance of aquatic animal diseases and pathogens. By collating historically published data, plus new aquatic pathogen and disease information, stakeholders will be able monitor fish kill and aquatic pathogen trends spatially and temporally in freshwater and marine environments...

The coronavirus pandemic, Chronic Wasting Disease (CWD) in white-tailed deer, and white-nose syndrome in bats have spawned great interest in diseases of native fish and wildlife. Many aspects of widely known diseases of wild (as opposed to domestic) animal populations are poorly understood, including their ecology, incidence, distribution, and methods for reducing effects of disease on culturally...

WHISPers, the Wildlife Health Information Sharing Partnership - event reporting system, is a web-based repository of basic information on current and historic wildlife mortality (death) and/or morbidity (illness) events reported by partners nationwide. It is also the portal to request diagnostic and epidemiologic services from the USGS National Wildlife Health Center.

Professionals at the NWHC include wildlife biologists, veterinarians, statisticians, epidemiologists, and informatics specialists. This multidisciplinary group conducts investigations and disease ecology studies of emerging and recurring priority wildlife diseases, maintains and analyzes comprehensive information on wildlife disease events, and provides response and management consultation and...

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...

Notable cases at the National Wildlife Health Center are highlighted here in the Pathology Case of the Month Series.

The USGS has developed the Rapid environmental (e)DNA Assessment and Deployment Initiative & Network (READI-Net) to accelerate the implementation of environmental DNA (eDNA) analysis as a best practice for the early detection of aquatic biological threats. READI-Net provides tools and a strategy to collect and deliver early detection data for natural resource managers and public health protection...

Instructions for reporting wildlife morbidity/mortality and submitting specimens to the USGS National Wildlife Health Center (NWHC).

Coral reefs are both ecologically and economically important, serving as nurseries for fisheries, protecting the coastline from storm surges, and generating income from tourism. Since 2014, a wide variety of corals have been dying from unexplained causes throughout South Florida with mortalities ranging from North Miami to the Florida Keys.
