Hábitos alimentarios del pargo mancha Lutjanus guttatus. (Pisces: Lutjanidae) en el Golfo de Nicoya, Costa Rica

Abstract

Un total de 504 "Pargo moteado" Lutjanus guttatus fueron colectados mensualmente en el Golfo de Nicoya, Costa Rica, desde enero de 1993 hasta enero de 1994 para determinar sus hábitos alimenticios. Los peces estudiados tenían entre 12 y 620 cm de longitud total y estaban vacíos. Tomando en cuenta toda la muestra, los camarones peneidos fueron el taxón más abundante, representaron el 59,3% de ocurrencia en los estómagos de los peces y el 79,3% de la biomasa. Sin embargo, mientras que el alimento principal en el contenido estomacal de los peces juveniles (menores de 30 cm de longitud total) eran los peneidos (Penaeus spp.), los de los peces más grandes eran los estomatópodos (Squilla spp.).

A total of 504 "Spotted Snapper" Lutjanus guttatus were collected monthly in the Gulf of Nicoya, Costa Rica, from January 1993 to January 1994 to determine its feeding habits. The fishes studied ranged 12-620 cm in total length and were empty. Taking into account the whole sample, peneid shrimps were the most abundant taxon, they accounted for 59.3% of occurrence in the fish stomachs and 79.3% of the biomass. However, whereas the main food item in the stomach contents of juvenile fishes (smaller than 30 cm in total length) were peneids (Penaeus spp.) that of bigger fishes were stomatopods (Squilla spp.).
