First approach to the trophic ecology and diet of the rainbow runner, elagatis bipinnulata (Quoy & Gaimard, 1825) (Pisces: Arangidae), in the central Colombian Caribbean

Abstract

The rainbow runner (Elagatis bipinnulata) scores high in trophic level (4.24) but it is not a voracious fish (Q/B = 10.8). Its diet is dominated by the dwarf herring (Jenkinsia lamprotaenia), eats more in the dry season, than in the rainy season and significantly more in the afternoon that in the morning suggesting preference for daylight feeding.
