Abstract EN
The Panama grunt is an abundant and commercially important species in the southeastern Gulf of California, but the research undertaken on this species is scarce despite its ecological and economic importance.
We studied the feeding habits of Panama grunt through stomach content analyses as a first step towards understanding the biology of this species in the study area.
Our results indicate that the Panama grunt is a benthic predator throughout its life cycle and feeds mainly on infaunal crustaceans.
Diet differences among grunt were not found according to size, diet, or season.
Shannon diversity index results indicate that Panama grunt has a limited trophic niche breadth with a diet dominated by a limited number of taxa as crustaceans.
The estimated trophic level of this species is 3.59.
Overall, the Panama grunt is a carnivorous fish occupying the intermediate levels of the trophic pyramid.
