This special issue of Aquaculture Economics and Management features six articles based on contributions to the International Association of Aquaculture Economics and Management (IAAEM) sponsored section on economics and marketing at the Aquaculture America onference in Las Vegas, Nevada, February 19–22, 2018. The IAAEM session contained 24 presentations in the program. The presentations highlight the increased importance of aquaculture production, supply chains and markets, and how this is caused by a number of innovations. As production and trade are expected to continue to increase (Kobayashi et al., 2015) and the market is becoming increasingly globalized (Anderson, Asche, & Garlock, 2018), these are factors that are likely to continue to be of high importance. There is, of course, now way the six articles in this special issue can represent the full extent of topics and species that were covered in all presentations. However, they provide a fair indication of the variation when it comes to topics, but less so when it comes to species. It is worthwhile to note that while there is an increasing focus on markets and demand, the special issue does not quite do justice to the many interesting contribution on the market side and particularly on demand and consumer preferences. Ecolabels have become an increasingly important part of the seafood market, and are increasingly important also for aquaculture products (Roheim, Bush, Asche, Sanchirico, & Uchida, 2018). The first paper in this issue, Amundsen et al. (2019) contributes to the discussion of the impacts of the ecolabels in investigating what levels of sustainability is addressed by common certification schemes. This is an important topic as the certification schemes are implemented at the farm level, but the environmental impacts are often measured at a regional level. Diseases are a significant risk and cost for most aquaculture species leading to production losses and price increases (Abolofia, Asche, & Wilen, 2017). It has been well documented how prevention and treatment can

整个供应链的创新

本期《水产养殖经济与管理》特刊基于对国际水产养殖经济与管理协会 (IAAEM) 赞助的 2018 年 2 月 19 日至 22 日在内华达州拉斯维加斯举行的美国水产养殖大会上的经济学和营销部分的贡献，收录了六篇文章。 IAAEM 会议包含 24 个节目中的演讲。演讲强调了水产养殖生产、供应链和市场的重要性日益增加，以及这是如何由一系列创新引起的。随着生产和贸易预计将继续增加（Kobayashi 等，2015）以及市​​场日益全球化（Anderson、Asche 和 Garlock，2018），这些因素可能会继续发挥重要作用。当然，还有 现在，本期特刊中的六篇文章可以代表所有演讲中涵盖的主题和物种的全部范围。然而，当涉及到主题时，它们提供了一个公平的变化迹象，但在物种方面则不然。值得注意的是，虽然市场和需求越来越受到关注，但特刊并没有完全体现市场方面的许多有趣贡献，特别是对需求和消费者偏好的贡献。生态标签已成为海鲜市场越来越重要的一部分，对水产养殖产品也越来越重要（Roheim、Bush、Asche、Sanchirico 和 Uchida，2018 年）。本期的第一篇论文，Amundsen 等人。（2019 年）有助于讨论生态标签在调查通用认证计划所解决的可持续性水平方面的影响。这是一个重要的主题，因为认证计划是在农场层面实施的，但环境影响通常在区域层面进行衡量。疾病是大多数水产养殖品种的重大风险和成本，导致生产损失和价格上涨（Abolofia、Asche 和 Wilen，2017 年）。预防和治疗如何能够被充分记录在案 疾病是大多数水产养殖品种的重大风险和成本，导致生产损失和价格上涨（Abolofia、Asche 和 Wilen，2017 年）。预防和治疗如何能够被充分记录在案 疾病是大多数水产养殖品种的重大风险和成本，导致生产损失和价格上涨（Abolofia、Asche 和 Wilen，2017 年）。预防和治疗如何能够被充分记录在案
