Abstract: This study elucidates the food intake and growth performance of wild whiting in captivity for 78 days using automatic demand feeding system. Whiting adapted well to using demand feeders. They fed approximately every 29-30 h at 19 oC during August-September and every 23 h at 15 oC in October. In the latter period, peak-feeding activities occurred between “dawn” and “noon” despite continuous 24 h lighting. During this period they ate similar daily amounts of dry weight to that predicted by the voluntarily feeding experiments using natural prey (0.78 %body wet weight (bw) day-1). However growth performance was poor (FCR ≈ 4.2), suggesting that digestibility was poor or that holding conditions/stress was diverting energy from the growth processes. Hierarchical dominance among the individual fish might exist among the experimental fish.
