A rapidly growing literature investigates how the recent Covid-19 pandemic has affected international seafood trade along multiple dimensions, creating opportunities as well as challenges. This suggests that many of the impacts of the Covid measures are subtle and require disaggregated data to allow the impacts in different supply chains to be teased out. In aggregate, Norwegian salmon exports have not been significantly impacted by Covid-related measures. Using firm-level data to all export destinations to examine the effects of lockdowns in different destination countries in 2020, we show that the Covid-related lockdown measures significantly impacted trade patterns for four product forms of salmon. The results also illustrate how the Covid measures create opportunities, as increased stringency of the measures increased trade for two of the product forms. We also find significant differences among firms' responses, with large firms with larger trade networks reacting more strongly to the Covid measures. The limited overall impacts and the significant dynamics at the firm level clearly show the resiliency of the salmon supply chains.
大量迅速增长的文献研究了近期的新冠疫情如何在多个层面影响国际海鲜贸易，既带来了机遇，也带来了挑战。这表明新冠措施的许多影响是微妙的，需要分类数据才能梳理出不同供应链中的影响。总体而言，挪威三文鱼出口并未受到与新冠相关措施的显著影响。利用面向所有出口目的地的企业层面数据，考察2020年不同目的地国家封锁措施的影响，我们发现与新冠相关的封锁措施对三文鱼的四种产品形式的贸易模式产生了显著影响。结果还说明了新冠措施如何创造机遇，因为措施的严格程度提高增加了两种产品形式的贸易。我们还发现企业的反应存在显著差异，贸易网络较大的大公司对新冠措施的反应更为强烈。总体影响有限以及企业层面的显著动态变化清楚地显示了三文鱼供应链的韧性。
