In order to enhance the survival and health status of Monopterus albus in early stocking, the variation of food consumption rate of cage-captured and electrofishing Monopterus albus was studied indoor under weak light less than 100lx and limitless consumption, and the effects of domestication on daily feeding rhythm were discussed. The research found that food consumption of electrofishing Monopterus albus was mainly at 19:00-22:00 (P<0.01), while cage-captured Monopterus albus had no apparent peak of food consumption (P>0.05). The electrofishing, cage-captured and domesticated Monopterus albus all showed apparent diurnal feeding rhythm (P<0.05): more active food consumption at night than that by day, and ceased food consumption for some periods by day. The Monopterus albus domesticated at 18:00 had one peak of food consumption at 18:00-19:00 daily (P<0.01), and there was no significant difference in proportion of food consumption between Monopterus albus feeding once a day and once every two days (P >0.05). The research showed that there was a definite diurnal feeding rhythm on Monopterus albus, electrofishing Monopterus albus also could be used in artificial breeding, and domestication at afternoon would help Monopterus albus to form a single peak diurnal feeding rhythm.
