This paper examines the structure of Norway's seafood trade, the world's second-largest exporter of seafood, focusing on the firms and industries involved in the transactions. Using highly disaggregated data from 2016 to 2020, the study reveals significant heterogeneity among exporting firms, ranging from very small to large firms handling a variety of products. The Norwegian seafood industry has a global reach, exporting to 172 different countries. There are 437 different exporting firms, but this is relatively few compared to the 11,024 different buyers. The average firm serves only 9 markets, but a handful of large exporters account for 39% of the total export value, highlighting significant synergies between the aquaculture, pelagic, and whitefish sectors. The paper also analyzes market concentration, product bundling, and the impact of Covid-19 on the industry. The findings suggest that the Norwegian seafood trade is resilient and flexible, with no major challenges observed during the pandemic.This paper examines the structure of Norway's seafood trade, the world's second-largest exporter of seafood, focusing on the firms and industries involved in the transactions.
