项目摘要

Aquaculture (the farming of aquatic animals and plants) is a US$143billion international industry and the fastest growing food production sector globally. It is thought to be the most sustainable source of animal protein and its sustainable development is key for meeting the nutritional needs of the expanding human population. Shrimp has been one of the most valuable internationally traded food commodities for many years, and accounted for a major part (16%) of the global aquaculture export industry in 2016 (US$22.9billion). In Bangladesh, the shrimp industry provides food security, income and employment for an estimated 15 million people (11% of the population) and is the country's second biggest export product, accounting for 3.61% of its GDP. Growth of the industry is largely through intensification of farming methods, but this is not being managed in a sustainable way, resulting in increased levels of disease and substantial environmental impact. The resources, infrastructure, and knowledge required to facilitate the rapid intensification of the industry are lacking, and as a result disease has become a huge economic and social problem. Our team has been working with in-country partners to help gain a better understanding of the diseases affecting the industry and ways in which it can mitigate for future outbreaks. We have identified shrimp hatcheries as a key target for strategies to improve the economic, social and environmental sustainability of shrimp farming. The 59 hatcheries in the Cox's Bazar region of Bangladesh are the foundation of the industry: they collect adult shrimp from the local Bay of Bengal and acquire their eggs, which they rear to a juvenile "seed" stage before onward supply to the 150,000 shrimp farmers across the country. Thus, they play a key role in sustaining the entire industry. Even so, currently they do not produce enough seed to meet demand and are estimated to be operating at less than 50% of capacity, mainly due to disease. Our research has shown that very few Bangladesh hatcheries adhere to the standard operating procedures that have been shown to reduce the incidence and spread of disease, with management practices varying significantly across the industry.In this project, we will work directly with 25% of the industry (15 hatcheries) in Bangladesh and carry out chemical and biological testing (i.e. testing for disease-causing microbes) of the water and animals at all the different stages of the hatchery process. We will also collect information on the hatchery management practices and finance records. This will allow us to identify ways in which each hatchery can better prevent and manage disease outbreaks whilst minimising their environmental impact. We will visit each hatchery to train all staff on biosecurity and present the data collected, before working with them to produce a bespoke management plan, which we will then support them to implement. We will also follow the seed produced by these "improved" hatcheries, to see whether they perform better than standard seed when introduced to farms, in terms of growth and health. Part of our work will involve working with the recipient farmers, to train them in the best way to introduce seed into their ponds, as our work has shown that this is the point in the farming process which incurs the greatest financial and animal losses. Finally, we will communicate the outcomes of the project through a wide range of media, to promote the uptake of these practices across Bangladesh. This will include institutional blogs and websites, a short online video aimed at a general audience, social media, project reports and peer-reviewed articles, and we will hold a stakeholder workshop at the end of the project to which all hatchery owners and other industry stakeholders will be invited. Overall our work should significantly improve the sustainability of the shrimp industry, by reducing levels of disease and improving the environmental impact.

水产养殖（水生动物和植物的养殖）是一个价值 1,430 亿美元的国际产业，也是全球增长最快的粮食生产部门。它被认为是最可持续的动物蛋白来源，其可持续发展是满足不断扩大的人口营养需求的关键。虾多年来一直是国际贸易中最有价值的食品商品之一，并在2016年占全球水产养殖出口业（229亿美元）的主要部分（16%）。在孟加拉国，虾业为约 1500 万人（占人口的 11%）提供粮食安全、收入和就业机会，是该国第二大出口产品，占国内生产总值的 3.61%。该行业的增长主要是通过集约化耕作方法实现的，但这并没有以可持续的方式进行管理，导致疾病水平增加和严重的环境影响。促进该行业快速集约化所需的资源、基础设施和知识缺乏，因此疾病已成为一个巨大的经济和社会问题。我们的团队一直在与国内合作伙伴合作，帮助更好地了解影响该行业的疾病以及减轻未来疫情爆发的方法。我们已将虾类孵化场确定为改善虾类养殖的经济、社会和环境可持续性战略的关键目标。孟加拉国考克斯巴扎尔地区的 59 个孵化场是该行业的基础：他们从当地孟加拉湾收集成年虾并获得卵，将其培育至幼虾“种子”阶段，然后再供应给 150,000 名虾农全国各地。因此，它们在维持整个行业方面发挥着关键作用。即便如此，目前他们仍无法生产足够的种子来满足需求，并且估计其产能利用率不到 50%，这主要是由于疾病的原因。我们的研究表明，很少有孟加拉国孵化场遵守标准操作程序，这些程序已被证明可以减少疾病的发生和传播，整个行业的管理实践差异很大。在这个项目中，我们将直接与 25% 的孵化场合作。孟加拉国的工业（15 个孵化场），并在孵化过程的所有不同阶段对水和动物进行化学和生物测试（即致病微生物测试）。我们还将收集有关孵化场管理实践和财务记录的信息。这将使我们能够确定每个孵化场如何更好地预防和管理疾病爆发，同时最大限度地减少其对环境的影响。我们将参观每个孵化场，对所有员工进行生物安全培训并展示收集到的数据，然后与他们合作制定定制的管理计划，然后我们将支持他们实施该计划。我们还将跟踪这些“改良”孵化场生产的种子，看看它们在引入农场时是否比标准种子在生长和健康方面表现更好。我们的部分工作将涉及与受援农民合作，培训他们以最佳方式将种子引入池塘，因为我们的工作表明，这是农业过程中造成最大经济和动物损失的关键点。最后，我们将通过广泛的媒体传播该项目的成果，以促进这些做法在孟加拉国的采用。这将包括机构博客和网站、针对普通观众的在线简短视频、社交媒体、项目报告和同行评审文章，我们将在项目结束时举办利益相关者研讨会，所有孵化场所有者和其他行业都将参加将邀请利益相关者。总的来说，我们的工作应该通过减少疾病水平和改善环境影响来显着提高虾业的可持续性。
