Pr<strong>in</strong>ciples <strong>of</strong> develop<strong>in</strong>g, validat<strong>in</strong>g and adopt<strong>in</strong>g BMPs <strong>in</strong> aquaculture - catfishcase studyThuy T. T. Nguyen & Sena S. De Silva<strong>Network</strong> <strong>of</strong> <strong>Aquaculture</strong> <strong>Centres</strong> <strong>in</strong> Asia-Pacific, Suraswadi Build<strong>in</strong>g,Department <strong>of</strong> Fisheries, Kasetsart University Campus, Bangkok 10900, ThailandAbstractThis document provides conceptual basis <strong>of</strong> Better Management Practices (BMPs) and methodologies to develop,implement and evaluate BMPs. In the case <strong>of</strong> catfish farm<strong>in</strong>g <strong>in</strong> Vietnam, a set <strong>of</strong> “draft” BMPs were developed forthree sectors: grow-out, nursery and hatchery, based on data <strong>of</strong> an extensive survey, coupled with the use <strong>of</strong> riskassessment tools and stakeholder discussion. This “draft” will be then tested at demonstration farms, deployedand improved over time. Experiences from development and implementation <strong>of</strong> BMPs <strong>in</strong> India <strong>in</strong> the shrimpfarm<strong>in</strong>g sectors are also be<strong>in</strong>g <strong>in</strong>corporated <strong>in</strong>to the Vietnam catfish case.What are Better Management Practices (BMPs)BMPs refer to a set <strong>of</strong> guidel<strong>in</strong>es that are developed, based on population based risk factor studies, <strong>in</strong> consultationwith the practitioners and relevant stakeholders and on the evaluation <strong>of</strong> current practices. Adoption <strong>of</strong> BMPs willlead to an improvement <strong>in</strong> the overall practices, reduce disease risk, improve yields, and contribute towardssusta<strong>in</strong>ability and economic viability.BMPs are a set <strong>of</strong> management guidel<strong>in</strong>es and are not standards, and the BMPs ensure that adoption <strong>of</strong> theguidel<strong>in</strong>es is relatively easy to achieve without <strong>in</strong>creased costs. The word “better” also implies that BMPs arealways evolv<strong>in</strong>g, open to improvement and <strong>in</strong>deed needs improvements as the culture practices progress.Adoption <strong>of</strong> BMPs are known to br<strong>in</strong>g about benefits such as:• Reduction and/or a m<strong>in</strong>imisation <strong>of</strong> disease occurrence,• Improved growth performance,• Decreas<strong>in</strong>g cost <strong>of</strong> farm<strong>in</strong>g,• Improved environmental conditions, and consequently m<strong>in</strong>imise impacts on the local environmental,• Atta<strong>in</strong> food quality standards,• Improve marketability <strong>of</strong> the produce, and• Facilitate susta<strong>in</strong>ability amongst others.Although most BMPs have an overall similarity <strong>in</strong> the guidel<strong>in</strong>es and the objectives, however, there is a significantlevel <strong>of</strong> variation between commodities and locations. Development <strong>of</strong> location specific BMPs andcontextualisation are an important part <strong>of</strong> the development process <strong>of</strong> BMPs.It is very clear that adoption <strong>of</strong> BMPs has brought about very significant beneficial impacts to farm<strong>in</strong>g systems, asbest exemplified <strong>in</strong> the case <strong>of</strong> the revival and the cont<strong>in</strong>ued sustenance <strong>of</strong> shrimp farm<strong>in</strong>g <strong>in</strong> India. In this<strong>in</strong>stance not only has the BMPs been adopted by <strong>in</strong>dividual farmers, the collective actions <strong>of</strong> the “clusters” <strong>of</strong>farmers, through formation <strong>of</strong> the societies have had improved yields, nearly m<strong>in</strong>imised disease occurrences,91
ought about <strong>in</strong>creased pr<strong>of</strong>its among other benefits. The results <strong>of</strong> this development, both adoption <strong>of</strong> BMPs andthe formation <strong>of</strong> clusters/ societies are schematically depicted <strong>in</strong> Figure 1.The results <strong>of</strong> this development, both adoption <strong>of</strong> BMPs and the formation <strong>of</strong> clusters/ societies are schematicallydepicted <strong>in</strong> Figure 1.Figure 1. Figure depict<strong>in</strong>g cluster/ society formations <strong>of</strong> shrimp farmers over the yearsOne question frequently asked by a wide range <strong>of</strong> stakeholder is:“How do BMPs differ from other extension messages commonly dissem<strong>in</strong>ated to farmers?”BMPs are science-based tools that are developed based on risk factor studies <strong>in</strong> farm<strong>in</strong>g systems. Interventionsdeveloped to address identified risk factors are collectively referred to as BMPs. Extension messages are <strong>of</strong>tenfocused on ways to <strong>in</strong>crease production and quality <strong>of</strong> the product. BMPs have an overall goal <strong>of</strong> promot<strong>in</strong>gresponsible and susta<strong>in</strong>able aquaculture, and not just promot<strong>in</strong>g higher production. Thus BMPs can helpproducers to farm commodities <strong>in</strong> a more susta<strong>in</strong>able way tak<strong>in</strong>g <strong>in</strong>to account also environmental and socioeconomicalconsiderations.Good <strong>Aquaculture</strong> Practices (GAPs) are commonly used to address food safety issues <strong>in</strong> aquaculture. These tendto be farm management practices prepared to m<strong>in</strong>imise the potential for farm-raised fishery products to becontam<strong>in</strong>ated with pathogens, chemicals, or unapproved or misused veter<strong>in</strong>ary drugs. GAPs can be def<strong>in</strong>ed asthose practices necessary to address food safety concerns <strong>in</strong> isolation.BMP are <strong>of</strong>ten voluntary practices, but can also be used as basis for local regulations, or even to meet and comply tostandards set by third party certification programmes.a) The term "better management practice"The term “better management practices” is used <strong>in</strong> several ways. It has been used to refer to the best-known wayto undertake any activity at a given time. In this sense, it probably refers to the practice or practices <strong>of</strong> only one or92
