摘要

No-take marine reserves (fish refuges-FR-in Mexico) eliminate fishing pressure for long periods in delimited areas, promoting fish reproduction and recruitment, recovery of fish community abundance and biomass, augment resistance and resilience in coral reef-associated marine ecosystems, and support local fishing-based economies. A FR was implemented on Akumal reef in 2015 limiting fishing for six years with the specific aim of increasing the biomass of commercial and sport-recreational interest fish species. However, no previous reference data were considered to establish an ecological baseline to quantify progress towards this aim, or to implement any other policy necessary to ensure compliance with this objective. To fill this gap, Akumal FR's current level of potential success was assessed (relating reef fish community characteristics and habitat components characteristics). FR's potential success was quantified as low due to the absence of 50% of listed commercial-sport fish species, critical biomass values for recorded species on the list, and generally low reef fish abundance and biomass values. In addition, current habitat condition is critical because of coral-algal phase shift, changes in coral community structure, and loss of reef structure and the associated reefs refuge function for fish species. Considering the performance of existing no-take marine reserves, Akumal low FR's potential success implies that a much longer no-take period (than the established six years), will be necessary to allow reef fish populations to recover biomass and attain functional levels within the ecosystem that could support on-going fishing impact. Based on this, a number of recommendations were established in order to strengthen the management provisions to allow the reef to attain a better condition, including an extension of the no-take period, enforcement of non-extractive uses, and simultaneous implementation of coastal management strategies.
