摘要

目前关于印度尼西亚虾农实施的生物安全措施的信息有限。本研究描述了印度尼西亚爪哇岛中小型虾场的农民人口特征、农场生物安全措施、农场生产和疾病状况。2019年11月至2020年5月进行了一项基于问卷的调查,以收集爪哇岛各个地区经营的对虾养殖场的数据。每一种被评估的生物安全措施都根据它是传统的风险因素还是保护因素,被分配了一个数字分数。根据自愿参加这项研究的90名虾农的回答,平均总体生物安全得分从32到54(满分为100)不等。大多数养殖场(88.9%)要么与其他养殖场共享水源,要么通过水渠与其他养殖场相连。农场设备共享在农场内部(91.1%)和农场之间(41%)都很常见。水预处理很常见(99%),但大约三分之一的养殖场在放养前没有对幼虫进行任何常规质量评估。平均而言,养殖场生产1.6公斤/平方米(95% CI: 1.2, 2.0)虾,收获尺寸为43只/公斤(95% CI: 37, 49),收获时平均重量为23.3克。随着整体生物安全评分的提高,池塘面积收获重量和收获时虾体大小呈增加趋势。这些结果表明,具有较好生物安全措施的农场往往具有较高的产量。

Survey of farm management and biosecurity practices on shrimp farms on Java Island, Indonesia
Current information on biosecurity measures implemented by shrimp farmers in Indonesia is limited. This study describes farmer demographic characteristics, on-farm biosecurity practices, farm production and disease status, among small and medium holder shrimp farms on Java Island, Indonesia. A questionnaire-based survey was conducted from November 2019 to May 2020 to collect data from shrimp farms operating in various regions of the Java Island. A numerical score was assigned for each of the assessed biosecurity practices, based on whether it was a conventional risk factor or a protective factor. Based on responses from 90 shrimp farmers, who volunteered to participate in the study, mean overall biosecurity scores ranged from 32 to 54 (out of a maximum score of 100). Most farms (88.9%) either shared common water sources with other aquaculture farms or were connected to other farms via water channel. Farm equipment sharing was common both within (91.1%) and between (41%) farms. Water pre-treatment was common (99%), but approximately a third of the farms did not practice any routine quality assessment for post larvae before stocking. On average, farms produced 1.6 kg/m2 (95% CI: 1.2, 2.0) of shrimp with a harvest size of 43 shrimp/kg (95% CI: 37, 49) or an average weight of 23.3 g at time of harvest. An increasing trend in harvest weight per pond area and shrimp size at harvest was noted with increasing overall biosecurity score. These results indicated that farms with better biosecurity practices tended to have a higher production yield.
