Resumen
Fish traps are extensively used in tropical and subtropical reef fisheries. Despite this, there is a significant lack of
extensive and consecutive research concerning the basic aspects of trap fishing. We herein compile the available
information from the main coral and rocky reef fish trap fisheries, and compared their main aspects (i.e., mesh
size, CPUE, catch composition, ghost fishing, and management) to assess the dynamics of these fisheries and
their environmental impact. The analysis revealed that most fish stocks showed declining trends, with only few
species under heavy management being capable of withstanding high fishing pressure. In other fisheries, due to
fishing down the web, miscellaneous reef fish comprised the bulk of the catch, while the proportion of high-value
landed species was insignificant. Gear restrictions remain the most common management method in trap fisheries; however, even the minimum mesh size has not been ubiquitously enforced, while due to great variability
of targeted fish species, use of a uniform mesh size is highly unlikely. Other management tools, such as, restrictions in effort, size, and species, temporal and spatial closures were also widely used, but effective only when
well enforced and interconnected. Rates of trap loss widely differed as well as the reported rates of ghost fishing
mortality. In most cases, incorporation of escape panels resulted in almost complete elimination of ghost fishing.
However, further research is required concerning these issues.
