Images: How Do Fish Find Their Way?
Fish like this surgeonfish are hatched as larvae in the open ocean and must find their way to coral reefs where they settle down, grow up, and live their lives. (Justin Suca, Woods Hole Oceanographic Institution)
An array of sound recorders are musterd on a dock in St. John, ready to be transported by boat out to sea and installed under water. They record the soundscape near coral reefs that larval fish may home in on to find coral reefs to settle on. (Jessica Perelman, University of Hawaii at Manoa)
Graduate student Justin Suca dives to the seafloor to install an undersea sound recorder. The recorders are deployed for months at a a time. To preserve power and space, the recorders awaken every ten minutes, for only a minute at a time, to record sounds in the ocean near coral reefs. (Ian Jones, Woods Hole Oceanographic Institution)
WHOI researchers also deployed net traps to intercept fish larvae journeying from the open ocean where they hatch to coral reef where they can settle down and live. The scientists are studying whether larvae use sound to navigate their way home. (Paul Caiger, NOAA)
