          Abstract

          Objetive. Fish species community structure and benthic organisms coverage were studied in five localities in Santa Marta where the lionfish is present. Materials and methods. Abundance of fish species, including lion fish, was established using 30 m random visual censuses and video transects; trophic guilds were established according to available references. On the other hand benthic coverage was evaluated using the software Coral Point Count (CPCe) 4.0. Results. Families with higher species numbers were Serranidae, Labridae, and Pomacentridae. Lionfish abundances were low (2.6±2.1 ind/120 m²), but in any case Pterois volitans was observed as the eleventh more abundant species, surpassing species of commercial value such as Cephalopholis cruentata. Species that were found in larger numbers (>100, Thalassoma bifasciatum, Haemulon aurolineatum, Canthigaster rostrata, Abudefduf saxatilis, Chromis cyanea, and Stegastes partitus) were mainly invertebrate eaters, planctivores, and territorial herbivores. Coral coverage showed higher coral percentages in Chengue (69.9%) and Cinto (27.4%), larger sponge percentages in Morro (32.7%); Isla Aguja and Remanso showed the larger figures for abiotic substrate (41.6 and 37%, respectively); corals, sponges, and gorgonians were the components best explaining fish community, but not for the lion fish, which inhabit all studied reef formations. Conclusions. Lion fish is ranked between the 20 more abundant species, with none commercially important species larger, hence no species may qualify as a natural control. Lion fish has as well become a relatively abundant species in Santa Marta reefs, independent of benthic coverage.

          Objectivo. Se estudió la estructura de especies de la comunidad íctica y se evaluó la cobertura de organismos bentónicos en cinco localidades en Santa Marta, Colombia con presencia del pez león. Materiales y métodos. Se estimó la abundancia a través de censos visuales y video transectos de 30 m y se estableció el gremio trófico de cada especie según literatura. El sustrato se cuantificó con el software Coral Point Count (CPCe) 4.0. Resultados. Las familias con más especies fueron Serranidae, Labridae y Pomacentridae y, aunque su abundancia promedio fue baja (2.6±2.1 ind/120 m²), Pterois volitans fue la undécima especie más abundante, superando a peces comerciales como Cephalopholis cruentata. Las especies más abundantes fueron invertívoros, planctívoros y herbívoros, tales como Thalassoma bifasciatum, Haemulon aurolineatum, Canthigaster rostrata, Abudefduf saxatilis, Chromis cyanea y Stegastes partitus. Se encontró mayor porcentaje de coral en Chengue (69.9%) y Cinto (27.4%) y de esponjas para Morro (32.7%); para Isla Aguja y Remanso predominó el componente abiótico (41.6 y 37%, respectivamente). Corales, esponjas y gorgonias fueron los componentes que mejor explicaron la comunidad íctica, aunque no para el pez león que habita todas las formaciones arrecifales. Conclusiones. El pez león se ubica entre las 20 especies de peces más abundante, con ninguna especie de importancia comercial en los sitios muestreados que lo supere en talla y que pudiera ser un control natural del invasor. Igualmente, se ha convertido en una especie relativamente abundante en los arrecifes samarios sin importar los atributos del fondo.

            Invasive Lionfish Drive Atlantic Coral Reef Fish Declines

            Indo-Pacific lionfish (Pterois volitans and P. miles) have spread swiftly across the Western Atlantic, producing a marine predator invasion of unparalleled speed and magnitude. There is growing concern that lionfish will affect the structure and function of invaded marine ecosystems, however detrimental impacts on natural communities have yet to be measured. Here we document the response of native fish communities to predation by lionfish populations on nine coral reefs off New Providence Island, Bahamas. We assessed lionfish diet through stomach contents analysis, and quantified changes in fish biomass through visual surveys of lionfish and native fishes at the sites over time. Lionfish abundance increased rapidly between 2004 and 2010, by which time lionfish comprised nearly 40% of the total predator biomass in the system. The increase in lionfish abundance coincided with a 65% decline in the biomass of the lionfish's 42 Atlantic prey fishes in just two years. Without prompt action to control increasing lionfish populations, similar effects across the region may have long-term negative implications for the structure of Atlantic marine communities, as well as the societies and economies that depend on them.
