Lab Theme & Vision
Conservation Biology of Fishes
Seeking to understand the impacts of environmental conditions on fish behavior, physiology, and their relationship with population dynamics. This includes incorporating effects of various components of the ecosystems (prey presence, interspecific interactions, and water chemistry) on fish behavior and population dynamics.
Results from these research topics are useful for natural resource managers making decisions associated with environmental impacts on natural (or artificially-enhanced) populations of fishes.
Projects are implemented by Dr. Zydlewski, staff, graduate students, undergraduate students, High School students.
- Presence and distribution of Atlantic and shortnose sturgeon in the Penobscot River and Gulf of Maine
- Application of modern acoustic technology and spatial analyses to estimate densities of aggregating sturgeon
- Assessing the impacts of tidal turbines on fishes using acoustic techniques
- Documenting spawning of shortnose sturgeon in the Penobscot River
- Hydroacoustic documentation of diadromous fish migrating in the lower Penobscot River

We study fish from cellular function and hormonal control of behavior to population-level responses to human-induced changes to their ecosystems.For example, this Atlantic Sturgeon was captured in the Penobscot River and has been tracked using a sonic tag. Some of our tagged Atlantic Sturgeon have been detected as far away as Halifax Nova Scotia and New York! See Altenritter et al. 2017 for more details!
