【摘要】 采用重点调查、抽样调查和问卷调查等方式,于2019年4月-2020年4月对江汉平原克氏原螯虾(Procambarus clarkii)养殖池杀青苔药物使用及流通状况进行了调研。研究发现大多数养殖户在11月至次年4月通过药物杀除青苔,同时考虑减少对水草的损伤。比较了不同养殖模式杀青苔药物的投入情况。调查结果表明:市售杀青苔药物以通过调控青苔细胞生理活动而杀死青苔的生物抑藻类为主,比较了不同剂型杀青苔药物的销量情况,分析了养殖户在杀青苔过程中以及杀青苔药物在销售环节存在的问题和原因,提出相应的对策和建议。本研究旨在为克氏原螯虾养殖池合理使用杀青苔药物以及规范管控杀青苔药物的流通提供参考。[中国渔业质量与标准,2021,11(6):23-29]更多还原

【Abstract】 Survey and analysis on the usage and circulation status of moss killer for Procambarus clarkia culture ponds in Jianghan Plain were carried out by key-point investigation, sample investigation and question investigation methods from April in 2019 to April in 2020. The research showed that most culturists applied drugs to kill moss from November to April in the following year, and paid attention to reduce the damage of moss killer to aquatic plants at the same time. Besides, the inputs of moss killer on different aquaculture models were compared. Algae bio-control killing moss by regulating physiological activities of moss cells accounted for the majority of moss killers saled in the market. The sales volume of moss killer with different dosage forms were compared. The existing problems and reasons of moss killer during the aquaculture process and the sales section were analyzed, and then the corresponding countermeasures and suggestions were put forward. Countermeasures and suggestions were targetedly given. This research aimed to provide reference on rational use of moss killer in Procambarus clarkia culture ponds and standard management for the circulation of moss killer.
