| 摘要: |
| 研究了凡纳滨对虾(Litopenaeus vannamei)“黑精荚”产生的病因及防治方法。结果表明:“黑精荚”是由于雄虾长时间生活在污物较多的池底中引发细菌感染而造成的。保持池底清洁、挤出黑精荚、投喂优质饵料和保持水温30℃以下, 可使精荚重新形成并发育成熟; 用二氧化氯和诺氟沙星联合用药使黑精荚恢复功能等措施可有效防治“黑精荚”病。 |

| Prevention and treatment of the “black-spermatophore” disease in Litopenaeus vannamei |

| Abstract: |
| In this paper, the causes for the “black-spermatophore” disease in Litopenaeus vannamei were investigated and the prevention and treatment meathods were figured out. The results showed that the “black-spermatophore” disease is caused by the bacteria infection when the male broodstock is cultured in the dirty sediment for a long time. The “black-spermatophore” disease can be prevented or got rid of and new spermatophores can be reformed by keeping the bottom clean, squeezing out black spermatophore, feeding high-quality food, and keeping water temperature below 30℃. The combination of chlorine dioxide and norfloxacin can be used to efficiently restore the function of spermatophores and prevent the “black-spermatophore” disease. |
