Nassau grouper migration patterns during full moon suggest collapsed historic fish spawning aggregation and evidence of an undocumented aggregation
Many fish species migrate to form fish spawning aggregations. The temporal and spatial predictability of these migrations and spawning aggregation locations makes species vulnerable to overfishing, as the majority of an adult population within a large region may be harvested quickly with minimal effort.
Integrating population biology into conservation management for endangered Nassau grouper Epinephelus striatus
Groupers are a phylogenetically diverse group and include many ecologically and economically valuable predatory marine fishes that have experienced drastic population declines. Reproduction via spawning aggregations increases the vulnerability of grouper species such as Nassau grouper Epinephelus striatus to overfishing, and this is likely to be a major contributing factor to population declines.
From 2011 to 2013, the Atlantis Blue Project Foundation (ABPF) supported the assessment of a total of 214 reefs throughout The Bahamas, including sites on Cay Sal Bank, Andros, the Southern Bahamas, New Providence and Rose Island, the Little Bahama Bank and partial surveys in the Exuma Cays and Berry Islands.
