The differences of tetrodotoxin (TTX) levels in various parts of pufferfish (Torquigener flavimaculosus) were examined in conjunction with the seasonal and sexual variations. The TTX levels in gonads, liver, intestines, skin and muscle tissue were determined using the Q-TOF LC/MS. Instrumental analysis revealed that all examined tissues from T. flavimaculosus contained high TTX concentrations. TTX levels in the gonads, liver, intestines, skin and muscle tissue of pufferfish were within the range of 5.03-100.71, 7.04-106.80, 12.59-86.30, 33.95-139.88 and 15.88-86.07 (μg/g), respectively. It was determined that in all seasons, except for summer, female individuals had higher TTX levels than males. Among all seasons, the highest level of TTX was found in winter and the lowest in autumn. Consequently, T. flavimaculosus is a highly toxic pufferfish that is dangerous for human consumption and should not be consumed under any circumstances.
结合季节性和性别差异，对斑纹东方鲀各部位的河豚毒素（TTX）水平差异进行了研究。使用Q-TOF LC/MS测定性腺、肝脏、肠道、皮肤和肌肉组织中的TTX水平。仪器分析表明，斑纹东方鲀所有检测组织均含有高浓度的TTX。河豚性腺、肝脏、肠道、皮肤和肌肉组织中的TTX水平分别在5.03 - 100.71、7.04 - 106.80、12.59 - 86.30、33.95 - 139.88和15.88 - 86.07（μg/g）范围内。结果表明，除夏季外，所有季节雌性个体的TTX水平均高于雄性。在所有季节中，TTX水平在冬季最高，秋季最低。因此，斑纹东方鲀是一种剧毒河豚，对人类食用具有危险性，在任何情况下都不应食用。
