Abstract: In this paper,the volatile compounds from the three cage-farming fishes such as Sciaenops ocellatus,Pseudosciaena crocea and Lateolabrax japonicus were extracted and identified by headspace solid phase micro-extraction(HS-SPME) and gas chromatography-mass spectrometry(GC-MS).The relative odor activity value(ROAV) in association with odor threshold was applied to confirm the key compounds of the fishes.The flavor characteristic and the sources of the key volatile compounds were also analyzed.The results indicated that Nonanal,(E,Z)-2,6-Nonadienal,Octanal,(Z)-4-Heptenal,(E)-2-Octenal,Hexanal,Heptanal,1-Octen-3-ol,2-Methyl butanal were the key odor compounds of Sciaenops ocellatus.The key odor compounds of Pseudosciaena crocea were Nonanal,(Z)-4-Heptenal,Hexanal,(E,E)-2,4-Heptadienal,Ethyl valerate,3-Hexen-1-ol,1-Octen-3-ol,2-Methyl butanal,Heptanal,Pentanal,(E)-2-Hexenal and 2-Pentylfuran.The flavor of Lateolabrax japonicus were composed of Nonanal,(E)-2-Nonenal,(E,Z)-2,6-Nonadienal,Octanal,(E)-2-Decenal,Hexanal,Heptanal,(Z)-4-Heptenal and 1-Octen-3-ol.
