Résumé

The common myctophids Stenobrachius leucopsarus, Diaphus theta and Tarletonbeania crenularis were found to feed primarily on the euphausiid Euphausia pacifica, the copepods Metridia lucens and Calanus spp., and the amphipod Parathemisto pacifica. The diets of these species of fishes were diverse and overlapped broadly, suggesting that they are feeding generalists. Most stomachs contained either all copepods or all euphausiids. Euphausiids were the most important prey on the basis of biomass. They comprised over one-half the weight of the stomach contents in over 40% of individuals of each of the three fishes. Stomach fullness and state of digestion of stomach contents differed over the diel period, but not enough to indicate feeding only during the nighttime. Average stomach fullness was greatest during the morning and night and well-digested material, which predominated in most stomachs, was most prevalent in the morning and afternoon. Either some feeding occurs throughout the day or digestion rates are slow.
