Fisheries Ecology & Conservation
Dr. Matt Ajemian joined Harbor Branch in 2016 as an Assistant Research Professor. His major research interests lie in the ecology and conservation of targeted fisheries and vulnerable species, and his experience includes a variety of marine and estuarine organisms from shellfish up to sharks and rays. Dr. Ajemian's work also spans a continuum of marine and estuarine ecosystems, ranging from confined inshore lagoons to offshore artificial and natural reefs. He employs integrative approaches to tackle research questions with both theoretical ecology and applied fisheries applications, often intertwined.
In general, his research seeks to:
Understand linkages between fisheries species and habitat quality (dynamic and fixed)
Expand scientific knowledge on fish behavior and ecology to promote population sustainability
Improve and utilize technological tools (e.g., biotelemetry) to delineate fish resource needs and multi-scale connectivity
- Provide imperative scientific data for stock assessment and natural resource management
Dr. Ajemian earned his Ph.D. in Marine Science at University of South Alabama and Dauphin Island Sea Lab in 2011 and spent four years as a postdoc and research scientist with the Center for Sportfish Science and Conservation at the Harte Research Institute for Gulf of Mexico Studies, Texas A&M University-Corpus Christi. Over the course of his career he has developed expertise in ichthyology, ecology, and fisheries science and has covered topics such as foraging ecology, habitat use, movement behavior, fisheries impacts, and bycatch.
