Abstract The global sea temperature continues to rise and reaches a new high in 2019. This phenomenon will force the migration of Scottish herring and mackerel to higher latitudes and severely inhibit the development of small-scale Scottish fishing companies. This paper establishes a grey prediction model, a regression analysis prediction model and a fuzzy comprehensive evaluation model to explore the migration locations of herring and mackerel in the next 50 years, and to formulate appropriate business strategies for small-scale Scottish fishing companies. The model results show that in the next 50 years, herring and mackerel will migrate to Greenland and Norwegian waters, and will migrate out of the fishing range of small fishing companies from 2046 to 2053. Therefore, reducing labour costs is the most appropriate business strategy.
