Below are journal articles about fish and aquatic animal health from the Eastern Ecological Science Center published in 2021 and 2022.
Aquatic Animal Physiology
USGS research examines how environmental change, both of 'natural' and 'human' origins, affects growth and development among fish species. Physiological systems such as ion regulation, stress, energetics, growth and reproduction are critical for survival of fish within many habitats. Physiological demands are especially important to anadromous fish because of their need to move between fresh water and seawater and to make long, often difficult migrations involving passage barriers and other changes in riverine ecosystems.

Tools and Methods Development
Developing and refining laboratory tools and techniques for evaluating aquatic animal health and disease parameters have historically been and continue to be an important component of our research program in USGS.
