Spawning Locations

Recent research on Eleuthera identified the general characteristics of bonefish spawning (October through April, near full and new moons, at night, in offshore waters).  Research on Eleuthera, Andros, and Abaco has revealed long-distance migrations from feeding grounds to probably spawning locations, suggesting that spawning locations may serve a large geographical area.  In conjunction with fishing guides on each island of the Bahamas, we will use tag-recapture, sonic tagging, and observation to identify bonefish spawning locations, and work with the guides to use this information to protect these important locations.

This work is already ongoing on Abaco. During the October 2010 – May 2011 spawning season, a female bonefish that was tagged with a sonic tag in the Marls was detected at a suspected spawning location on the southern tip of Abaco, suggesting both a spawning location and a connection between the Marls and this location. We plan to repeat this study, with a greater number of bonefish tagged, in the 2012 – 2013 spawning season. Read more about the Abaco project.
