The Scottish autumn mackerel fishery has commenced, with fishermen reporting good catches of high-quality fish to the east of Shetland. The fishery enjoys strong market demand, especially from Japan, where export sales of frozen whole Scottish mackerel have surged from 1,074 tonnes in 2020 to 15,316 tonnes in 2023, valued at around £25m. Scottish processors are working to increase their market share in east Asian markets, leveraging the superior quality of Scottish mackerel caught in October.
