dc.description.abstract Recently, Pterois volitans, one of the species known as lionfish, invaded the Atlantic Ocean. Individuals of P. volitans from Puerto Rico (N=188), Cayman Islands (N=91) and Bahamas (N=47) were examined for parasites. A total of 26 parasitic species, including the digenean Lecithochirium floridense, the leech, Trachelobdella lubrica, other digeneans, monogeneans, cestodes, nematodes, isopods a copepod and an acanthocephalan were recovered. Twenty-four new species infecting P. volitans, 5 new locality records from Puerto Rico, 10 from Cayman Islands, 6 from the Bahamas, 6 from the Caribbean and 4 from the subtropical western Atlantic region. Also, 2 first fish-association records are reported. Results from samples from Puerto Rico collected between 2009-2012 indicate there was no significant difference between yearly community compositions, although there was an incremental increase of parasitic species with time. Results suggest that lionfish communities were similar in composition, due to high abundances of L. floridense in the samples. Some of the observed species infecting lionfish are known to kill native fish species; however lower prevalences were recorded. Monitoring the development of parasite infestations in this host should continue throughout its range. Also, monitoring the impact of parasites on the fitness of this fish in its invasive range should be considered. en_US
dc.description.abstract Pterois volitans, una de las especies conocidas como “pez león”, recientemente invadió el Océano Atlántico. Individuos de P. volitans colectados en Puerto Rico (N= 188), Islas Cayman (N= 91) y en Las Bahamas (N= 47) fueron examinados para detectar la prescencia de parásitos. En total, unas 26 especies fueron colectadas, incluyendo el digeneo Lecithochirium floridense, la sanguijuela Trachelobdella lubrica, otros digeneos, monogeneos, céstodos, nemátodos, isópodos, un copepodo y un acantocéfalo fueron recuperados. En este estudio se reportan 24 nuevas especies infectando a P. volitans, 5 nuevos reportes de especies de Puerto Rico, 10 de las Islas Cayman, 6 de las Bahamas y 6 de la región del Caribe y 4 de la región subtropical del oeste Atlántico. También, reportamos 2 primeras asociaciones de parásitos con un pez. Resultados de muestras de Puerto Rico colectadas entre 2009-2012 indican que no existe diferencia significativa entre la composición anual de comunidades de parasitos asociados al pez león, aunque se observó un incremento de especies parasíticas con el tiempo. Resultados sugieren que las comunidades de pez león son similares en composición debido a la gran abundancia de L. floridense en las muestras. Algunas de las especies que infectan al pez león son conocidas por matar especies de peces nativos, sin embargo, nuestros valores de prevalencia fueron menores. Desarrollo de infestaciones parasíticas en este huésped deberian ser monitoreadas a lo largo del rango de esta especie invasiva. Además, monitoreos del impacto de especies parasíticas sobre la aptitud de este pez deberían ser considerados. en_US
