Diet Analysis of Mahimahi (Coryphaena spp.) Caught On Oʻahu, Hawaiʻi, Using DNA Barcoding

July 17, 2024

This study provides evidence that mahimahi consume a wide variety of prey taxa that spans multiple habitats and taxonomic guilds.

Mahimahi are predatory fishes that inhabit tropical and subtropical waters globally. Previous research targeting stomach contents found mahimahi to feed on a variety of fishes, cephalopods, and crustaceans. However, the degraded nature of stomach contents limits species-level identifications. In this study, we examine mahimahi diets from 200 stomachs collected around Oʻahu from 2019–2022 using a DNA barcoding approach to increase the taxonomic resolution of prey items.
