疾病一直被认为是孟加拉国对虾(Penaeus Monodon)和罗氏沼虾(Macrobrachium Rosenbergii)水产养殖生产的主要障碍。这项研究评估了与处理化学和生物制品以预防和治疗对虾和对虾疾病有关的对虾和对虾疾病/症状、健康管理做法和职业健康危害。2016年2月至6月，孟加拉国西南部对380名对虾和对虾养殖户进行了一项半结构问卷调查。这些养殖场根据三种种植模式进行了分类：对虾混养、对虾混养和对虾和对虾混养。接受调查的农民报告了八种不同的疾病和/或症状。对虾和对虾分别以白斑病和触角折断症状最为常见。总共使用了35种化学和生物制品(4种抗生素、15种消毒剂、13种杀虫剂、2种饲料添加剂和益生菌)来治疗和/或预防所有农场类别的疾病。疾病管理的主要制约因素是获得疾病诊断服务的机会有限、产品应用信息不足以及缺乏关于更好的管理做法的知识。徒手处理化学品和配制药物饲料被确定为潜在的职业健康危害。这项研究建议提高农民在疾病诊断和健康管理实践方面的知识和技能，并适当处理潜在危险的化学品。
Diseases have been recognized as the major obstacle to the shrimp (Penaeus monodon) and prawn (Macrobrachium rosenbergii) aquaculture production in Bangladesh. This study provides an assessment of shrimp and prawn diseases/syndromes, health management practices, and occupational health hazards associated with the handling of chemical and biological products to prevent and treat shrimp and prawn diseases. A survey was conducted using a semi-structured questionnaire with 380 shrimp and prawn farmers in the southwest of Bangladesh during February and June of 2016. The farms were categorized on the basis of the three cropping patterns: shrimp polyculture, prawn polyculture, and shrimp and prawn polyculture. Eight different diseases and/or symptoms were reported by the surveyed farmers. The white spot disease and the broken antenna and rostrum symptom were the most common in shrimp and prawn species, respectively. In total, 35 chemical and biological products (4 antibiotics, 15 disinfectants, 13 pesticides, 2 feed additives and probiotics) were used to treat and/or prevent diseases in the all farm categories. The major constraints for disease management were limited access to disease diagnostic service, inadequate product application information and lack of knowledge on better management practices. Handling chemicals and preparation of medicated feed with bare hands was identified as a potential occupational health hazard. This study suggests improvements in farmers' knowledge and skill in disease diagnostics and health management practices, and appropriate handling of potentially hazardous chemicals.
