Abstract

The larvae of the Korean bullhead, Pseudobagrus fulvidraco were satiated with the food uptake equivalent to 13% of its body weight and required 2.5, 11 and 15 hrs to digest 50, 90 and 100% of the consumed food. The juveniles were satiated with food equivalent to 0.65% of its body weight and required 9 and 19 hrs to digest 50 and 90% of the consumer. Apparently, daily food intake perceptibly decrease with the larvae grew to juvenile stage. Both larvae (8.3-14.0mm TL) and juvenile (41.1-65.7mm TL) tend to feed frequently than to get satiated once a day and appeared to be nocturnal feeders.
