Resumo

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.
