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 U.S. Geological Survey’s Eastern Ecological Science Center is home to the Northeast Amphibian Research and Monitoring Initiative (NEARMI), one of 7 ARMI regions across the United States. NEARMI works on public lands in thirteen states from Maine to Virginia, including many National Parks and National Wildlife Refuges.

This project focuses on understanding the forces driving the risk of avian influenza transmission from wild waterfowl to domestic poultry within the Chesapeake Bay region.

This project focuses on improving our understanding of how current and previous infection with avian influenza viruses impact the movement ecology of wild waterfowl species.

Issue The USGS has a long-term research effort that identified endocrine disruption in smallmouth bass (SMB) in the Chesapeake Bay watershed. Endocrine disruption can cause many changes in fish, including intersex characteristics where fish develop characteristics of the other sex, such as immature eggs forming in males. An overview by USGS of endocrine disruption in fish found the condition...

Issue Partners in the Chesapeake Bay Program (CBP) are implementing best management practices (BMPs) to prevent nutrient and sediment from entering waterways across the Chesapeake watershed and reduce loads to the Bay. In addition to reducing nutrients, CBP partners want to better understand how BMPs can provide additional benefits for addressing toxic contaminants, such as pesticides, hormones...

Below are journal articles about fish and aquatic animal health from the Eastern Ecological Science Center published in 2021 and 2022.

Southeast Asia has long been the epicenter of AIV emergence. However, as demonstrated by H5NX, these viruses can quickly reach global spread and have significant impacts on poultry production and human health. We have two ongoing efforts funded by the National Science Foundation to help improve our understanding of AIV emergence, spread, and transmission in today’s rapidly changing landscape.

Dietary analyses, health, and reproduction of blue catfish in tributaries of the Chesapeake Bay inform ecosystem impacts and mitigation strategies for this aquatic nuisance species.

Black basses (Micropterus spp) are enigmatic North American sportfishes that support the most economically valuable freshwater sport fishery in the United States and serve as keystone predators within aquatic ecosystems. Hyperpigmented melanistic lesions on the surface of black basses have been observed in a number of waterbodies across the country in increasing frequency. We have recently...

The Eastern Ecological Science Center is working closely with federal, state, and tribal partners to help inform decisions that reduce the risk of SARS-CoV-2 transmission from humans to North American wildlife, including bats.
