Abstract (en):
Invasive species are the second main cause of extinction after habitat loss. Lionfish, Pterois volitans (Linnaeus 1758), was seen by the first time in southern Florida in 1985. Since 2000 it has dispersed and established in the eastern coast of the United States and in Bermuda and Bahamas; since 2007 it has expanded through the Caribbean, appearing in oceanic Colombia in 2008 and in continental Colombia in 2009. In order to characterize the lionfish population inhabiting the Colombian Caribbean a literature revision was made as well as collects. Merisitc and morphometric data were taken in the laboratory from a sample of 63 specimens, 36.3-183.0 mm standard length (SL) (from a total of 280 collected individuals). The counts found were: dorsal fin XIII,11 (rarely XIII,12); anal fin III,7 (rarely III,8); pectoral fin 14 (rarely 13). The main measurements (in percentages of SL) found were head length 29,7 - 40,7% and eye diameter 5,6 - 9,1%.
Abstract (es):
Las especies invasoras representan una de las principales causas de extinción de la biodiversidad, por lo que son consideradas el segundo motivo, después de la pérdida de hábitat. El pez león Pterois volitans (Linnaeus 1758) fue visto por primera vez al sur de Florida en 1985. Desde 2000 se ha dispersado y establecido en la costa este de Estados Unidos, Bermudas, Bahamas, y desde 2007 se ha expandido por el Caribe, registrándose en localidades oceánicas y continentales de Colombia en 2008 y 2009, respectivamente. Para caracterizar la población residente de P. volitans en aguas del Caribe colombiano se hizo una revisión de literatura y se realizaron colectas de la especie. En el laboratorio se efectuó la caracterización merística y morfométrica de una muestra de la población. Se obtuvieron 280 ejemplares provenientes de la región de Santa Marta, tomándose al azar 63 entre 36,3 y 183,0 mm de longitud estándar (LE), realizándose los conteos y medidas pertinentes; los datos merísticos se presentan siguiendo las convenciones ictiológicas y los morfométricos en porcentajes de LE. Los valores encontrados son: aleta dorsal XIII,11 (raro XIII,12); aleta anal III,7 (raro III,8); aleta pectoral 14 (raro 13); longitud cabeza 29,7 - 40,7%; diámetro ojo: 5,6 - 9,1%.
