Tropical flats as important habitat for bonefish

 

Flats are shallow tropical and subtropical marine environments comprised of several distinct habitat types, such as mangrove creeks, seagrass beds, and macroalgae and sand plains.  Bonefish (Albula spp.) are a group of fish that epitomize the interconnectedness of habitats within the flats ecosystem.  Because of the broad habitat requirements of bonefish during their lifecycle, bonefish populations could easily be disrupted by the modification or destruction of coastal ecosystems.

The critical role of bonefish in the ecology of the flats is especially significant since bonefish carry the distinction of being a highly prized sport fish worldwide.  The Bahamas is one of the top destinations for bonefishing in the Caribbean, and this form of tourism contributes significantly to the economy of many local communities.  Nevertheless, angling practices that do not maximize the post-release survival of bonefish could reduce adult bonefish numbers to unsustainable levels while also threatening the integrity of the flats ecosystems.  One goal of the Bonefish Research project is to examine the behavior and habitat use of bonefish off Cape Eleuthera.  We will be tracking bonefish using acoustic telemetry in several creeks systems to monitor their habitat use and survival post angling.  Concurrently, we will be mapping the creek systems in which these bonefish reside.  Lastly, we will be conducting surveys and life histories in local communities to gather information on the history of recreational angling on Eleuthera.
