    Abstract

    ScientiWc information on reef Wsh spawning aggregation Wsheries is sparse in light of numerous regional declines and extirpations from overexploitation. Fisher interviews of the small-scale commercial mutton snapper (Lutjanus analis) spawning aggregation Wshery at Gladden Spit, Belize, suggests a historic decadal decline. The reported trend is supported by analysis of inter-seasonal catch and eVort and yield (2000–2002) that reveals a 59% decline in catch per unit eVort (CPUE) and a 22% decrease in mean landings per boat. Declining population-level trends are also supported by a signiWcant decrease in interannual median lengths of mutton snappers (2000–2006). These Wndings demonstrate the need for additional life history information that includes length-associated age and details on growth to provide clearer support of the eVects on, and responses by, populations following Wshing. In view of the historical changes to mutton snapper CPUE and landings at Gladden Spit and the Wshery-associated declines in Wsh spawning aggregations observed globally, a precautionary approach to spawning aggregation management is warranted that provides full protection from Wshing to enhance population persistence. The Wndings also highlight the need for substantially greater enforcement and longterm Wsheries monitoring under a comprehensive regional management strategy.
