Food habits of Mustelus lunulatus and M. henlei (PISCES: TRIAKIDAE) colected in Parque Nacional Natural Gorgona, Colombian PacificAbstract
From June 1988 to July 1992, non-continuous samples of two species of cartilaginous fish of the family Triakidae were taken in the National Natural Park Gorgona. Stomach contents of 139 individuals of Mustelus lunulatus and 51 individuals of M. henlei were analyzed. These species predate on crustaceans (93,06%), mainly Portunus iridiscens, Squilla panamensis and Hipoconcha panamensis, secondly on mollusks of the family Loliginidae (4,32%) and fishes (2,28%) in a smaller proportion; the remaining 0,34% corresponded to digested material. Nematodes and isopods were found in the stomach contents of these fishes, but we considered them as accidentals and were not included in the analysis.Durante junio de 1988 a julio de 1992 se realizaron muestreos no continuos en el Parque Nacional Natural Gorgona donde se colectó información sobre el contenido estomacal de dos especies de peces cartilaginosos de la familia Triakidae. Del total de muestras obtenidas 139 correspondieron a contenido estomacal de Mustelus lunulatus y 51 a M. henlei. En general estas especies depredan sobre crustáceos (93,06%) principalmente Portunus iridiscens, Squilla panamensis e Hipoconcha panamensis, en segundo lugar se encuentran los moluscos de la familia Loliginidae (4,32%) y en menor proporción peces (2,28%); el restante 0,34% corresponde a material digerido. En el contenido estomacal de estos organismos se encontraron nemátodos e isópodos los cuales no se tuvieron en cuenta en el análisis, pues se los consideró como accidentales.
