          Abstract

          ABSTRACT The abundance of the invasive lionfish Pterois volitans was assessed through visual censuses conducted in 2015 and 2016 at 54 sites in six localities with coral reefs across the Colombian Caribbean coast. The invader was observed across locations and in most of the dives, with sighting frequency of 88 %, abundance values from 0 to 9.7 ± 2.1 ind/250 m2 (388 ind/ha), and 0.8 ± 1.3 ind/250 m2 (32 ind/ha) as total mean. The average density was similar to values reported in other works that counted lionfish in a broad spatial scale on the invaded area and the highest value approximated the maximum density estimated in Colombia and other locations around the Caribbean.

          RESUMEN Se evaluó la abundancia del pez león invasor Pterois volitans mediante censos visuales realizados en 2015 y 2016 en 54 sitios de seis localidades con arrecifes de coral a lo largo de la costa Caribe colombiana. El invasor se observó en todos los lugares y en la mayoría de las inmersiones, con una frecuencia de avistamiento de 88 %, valores de abundancia desde 0 hasta 9,7 ± 2,1 ind/250 m2 (388 ind/ha) y un promedio de 0,8 ± 1,3 ind/250 m2 (32 ind/ha). La densidad media fue similar a los valores reportados en otros trabajos que contaron pez león en una amplia escala espacial en el área invadida y el valor más alto se aproximó a la densidad máxima estimada en Colombia y otros lugares del Caribe.

            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.
