Bio

Kohma Arai is a PhD student and Graduate Research Assistant working in the lab of Dr. Dave Secor at the Chesapeake Biological Lab. He is interested in studying diverse migration patterns of important fish species and how those behaviors influence the entire fish population structure and dynamics. Specifically, he focuses on evaluating decadal trends in stock mixing of the Northwest Atlantic mackerel through otolith stable isotopes and the influence of stock mixing on fisheries landings. He also studies nursery habitat-use of Hudson River striped bass using otolith chemistry and microstructural analysis.
