The Bahamas has some of the largest remaining populations of endangered Nassau grouper. However, these populations are in decline. In partnership with the Bahamian PhD candidate Krista Sherman, we are unlocking the mysteries of Nassau grouper populations in The Bahamas using advanced genetic techniques. This research is aimed at determining how Nassau grouper from different populations are connected, how fish living in different areas come together at spawning aggregation sites, and how populations have experienced a bottleneck, reducing genetic diversity in different parts of The Bahamas. The answer to these questions may lie in the DNA of these fish. Understanding the answers to these questions will help guide management of stocks to allow them to rebuild in key areas.
