08 Mar: Fish Flow: Filling the gap between spawning and settlement

PI: Brian Bowen
This project aimed to track reef fish, using their genetic data, from where they spawned as larvae to where they settle on the reef, as a direct measure of population connectivity. Engaging student volunteers, the research team collected over 1500 samples of three target species across the Hawaiian islands. Using advanced genetic technology and computer-aided population connectivity texts, the team generated maps that illustrate that most adult reef fish in Kāneʻohe Bay originate from neighboring East Oʻahu reefs rather than from inside the bay, useful information for appropriate managers.
