Abundance of the invasive lionfish Pterois volitans in the coastal coral reefs from Colombian CaribbeanAbstract
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.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.
