Hoplosternum littorale is a siluriform fish of very high commercial value in some country of South America. Some biological characteristics as easy spawning in confinement and good tolerance of low oxygen level make it easy to cultivate. Aquatic oxygen uptake does not allow to sustain standard metabolism, so it is considered as an obligated air breather. Routine metabolism and growth cannot be completed without air access. A circadian rythm for feeding behaviour is observed. Most voluntary food intake occur during the night. The sunset is a directive factor even in case of time lag. So, a night feeding schedule should bbe used in practise. (D'après résumé d'auteur)
