常用抗菌药物和消毒剂对刺参幼体的急性毒性试验结果表明:抗菌药物对幼参的毒性依次为土霉素>氟哌酸>新诺明,土霉素对刺参幼体24、48h的LC50分别为166、115mg/L,氟哌酸24、48h的LC50分别为457、407mg/L,新诺明48、72h的LC50为300、224mg/L;常用消毒剂对幼参的毒性依次为二氧化氯>高锰酸钾>福尔马林>次氯酸钠>敌百虫,二氧化氯有效氯对刺参幼体24h的LC50为0.36mg/L,高锰酸钾24、48、72h的LC50分别为3.02、2.09、1.26mg/L,福尔马林24、48、72h的LC50(体积分数)分别为8.71×10-6、4.37×10-6、1.62×10-6,次氯酸钠有效氯24、48、72h和96h的LC50(体积分数)分别为44.7×10-6、14.5×10-6、10.0×10-6和9.3×10-6,敌百虫24、48、72h和96hLC50分别为479、158、105mg/L和78mg/L。另外,作者还描述了刺参幼体对常用消毒剂和抗菌药物的反应,推算了其安全浓度,探讨了常用消毒剂和抗菌药物在刺参养殖中使用的可行性。
The results showed that the toxicity of antibacterials to young ginseng was oxytetracycline> norfloxacin> neo-naming and oxytetracycline, respectively. The LC50 of 24 hours and 48 hours Respectively, the LC50 of norfloxacin 24 and 48h were 457 and 407 mg / L respectively, and the LC50 of cotrimoxazole 48 and 72h was 300 and 224 mg / L, respectively. The toxicity of common disinfectants to the juveniles was two Chlorine dioxide> potassium permanganate> formalin> sodium hypochlorite> trichlorfon, chlorine dioxide effective chlorine on the sea cucumber larvae 24h LC50 0.36mg / L, potassium permanganate 24,48,72 h LC50 were 3.02, 2.09 and 1.26 mg / L respectively, and the LC50 (volume fraction) of formalin at 24, 48 and 72h were 8.71 × 10-6, 4.37 × 10-6 and 1.62 × 10-6, respectively. , LC50 (volume fraction) at 72h and 96h were 44.7 × 10-6, 14.5 × 10-6, 10.0 × 10-6 and 9.3 × 10-6, respectively. The trichlorfon’s 24, 48, 72h and 96hLC50 were 479, 158, 105 mg / L and 78 mg / L. In addition, the author also described the response of sea cucumber seedlings to commonly used disinfectants and antimicrobial agents, and calculated their safe concentrations. The feasibility of using common disinfectants and antimicrobial agents in the culture of sea cucumber was also discussed.
