Abstract: The paper aims to explore suitable bait for parental breeding of Thais bronni. Selective feeding of Thais bronni on seven baits, Ruditapes philippinarum, Sinonovacula constricta, Gomphina veneriformis, Mytilusedulis, Septifer virgatus, small crab and Scomber japonicus, was studied under water temperature of 22- 25℃, specific gravity of seawater 1.013-1.015, and dissolved oxygen level of 4-5 mg/L. The results indicated that T. bronni showed great interest on Septifer virgatus, positive selection to Sinonovacula constricta, Mytilusedulis, and small crab, but negative selection to Ruditapes philippinarum, Gomphina veneriformis, Scomber japonicus, with a clear negative selection order from weak to strong as Gomphina veneriformis, Ruditapes philippinarum, spawning Gomphina veneriformis, spawning Ruditapes philippinarum, Scomber japonicus.
