In the context of the fast-expanding shrimp farming industry in Sri Lanka, this study aimed to evaluate the distribution and understanding of BMPs, examine the relationship between BMPs and disease outbreaks, and analyze the current antibiotic usage trends through a fact-finding survey.
A questionnaire survey was conducted in 131 shrimp farms located in Puttalam District in North Western Province, where shrimp farming is thriving in Sri Lanka. The survey was conducted from September to October 2021. In addition, in August 2022 and August 2023, interviews were conducted with shrimp farms in Puttalam district and Batticaloa district, shrimp hatcheries, and export companies. Data were analyzed using descriptive statistics, Probit, and Tobit regression analysis.
The item-count technique revealed a significant (p < 0.05) difference in the use of antibiotics without consulting experts, signifying inappropriate use. No aquaculture farmer reported being unaware of BMPs, and among the 45 farmers who attended a BMPs seminar, 30 claimed to possess a good understanding of BMPs. Probit and Tobit regression results revealed that the rate of understanding of BMPs, education level, and obtaining information on the sanitation management of shrimp farming from extension and guidance organizations were inversely associated with both disease incidence in shrimp farming and shrimp discards.
Although the use of antibiotics is prohibited in BMPs, the analysis results suggest inappropriate use of antibiotics. The findings indicate that enhanced BMP understanding can reduce disease incidence and shrimp discards, emphasizing the need for incentives to promote BMP adoption and reduce the necessity for antibiotics.
在斯里兰卡对虾养殖业快速扩张的背景下，本研究旨在通过一项实情调查评估最佳管理措施（BMPs）的分布与认知情况，研究BMPs与疾病暴发之间的关系，并分析当前抗生素使用趋势。
在斯里兰卡对虾养殖蓬勃发展的西北省普塔勒姆区的131个对虾养殖场进行了问卷调查。调查于2021年9月至10月进行。此外，在2022年8月和2023年8月，对普塔勒姆区和拜蒂克洛区的对虾养殖场、对虾孵化场及出口公司进行了访谈。使用描述性统计、Probit和Tobit回归分析对数据进行了分析。
项目计数技术显示，在未咨询专家的情况下使用抗生素存在显著（p < 0.05）差异，这表明使用不当。没有水产养殖农户报告不知道BMPs，在参加BMPs研讨会的45名农户中，有30人声称对BMPs有很好的理解。Probit和Tobit回归结果显示，对BMPs的理解程度、教育水平以及从推广和指导组织获得对虾养殖卫生管理信息与对虾养殖中的疾病发病率和对虾丢弃率均呈负相关。
尽管BMPs中禁止使用抗生素，但分析结果表明存在抗生素使用不当的情况。研究结果表明，加强对BMPs的理解可以降低疾病发病率和对虾丢弃率，强调需要采取激励措施来促进采用BMPs并减少对抗生素的需求。
