以广东省养殖罗非鱼及南美白对虾为实验对象,就其体内土霉素等多种渔药残留及分布状况进行研究, 比较不同规格罗非鱼及南美白对虾体内渔药残留差异,分析渔药在罗非鱼及南美白对虾不同部位的残留状况。结果表明在罗非鱼体内已烯雌酚、呋喃唑酮、氯霉素3种渔药未见检出,南美白对虾体内已烯雌酚、呋喃唑酮、氯霉素、(口恶)喹酸和喹乙醇5种渔药均未见检出,而土霉素等常规用药在罗非鱼和南美白对虾体内均有不同程度的检出。渔药残留量因其规格大小及部位而异,趋势为大规格样品渔药残留量相对较高,在罗非鱼及南美白对虾体内的增长情况与其体重具有负相关性;罗非鱼内脏渔药残留量明显高于肌肉组织,虾头为虾渔药残留的主要场所。
Taking tilapia farmed in Guangdong Province and P. vannamei as experimental subjects, the residues and distribution of many fishery drugs such as oxytetracycline in their body were studied. The differences of the residues of fishery drugs in different sizes of tilapia and P. vannamei were analyzed. Residues of fishery in different parts of tilapia and P. vannamei. The results showed that none of the three kinds of fishery drugs such as diethylstilbestrol, furazolidone and chloramphenicol were detected in the tilapia. The diets of diethylstilbestrol, furazolidone, chloramphenicol, No detection of 5 kinds of fishery drugs, and oxytetracycline and other conventional drug use in tilapia and Penaeus vannamei have different levels of detection. Fishery residues vary in size and location. The trend is that there is a relatively high level of residual drug residues in large-size samples. There is a negative correlation between the growth of tilapia and P. vannamei and its body weight; Drug residue was significantly higher than muscle tissue, shrimp head shrimp fishery residues the main place.
