Kohma H. Arai

Kohma Arai is a PhD Candidate and Graduate Research Assistant working in the lab of Dr. David Secor at the Chesapeake Biological Lab. He is interested in studying the causes of diverse migration patterns of important fish species and the consequences of those behaviors on population structure and dynamics. His dissertation work focuses on (i) evaluating long-term trends in stock mixing and spatial structure of the Northwest Atlantic mackerel through otolith stable isotopes, isoscapes, and machine learning classification; and (ii) studying the causes and consequences of early life history partial migration of Hudson River striped bass through otolith chemistry, microstructure, and time series analysis.
