Fish and chips also have a large cultural impact, stemming from working-class traditions. Fish suppers have provided an affordable, high-energy meal for fishermen, dockworkers, and laborers for hundreds of years. The economic impact is quite significant. It is estimated there are as many as 25,000 Scottish seafood and fishing employees in this sector, though the sector is shrinking due to economic challenges such as rising vessel fuel costs, dynamic fish pricing, and energy price hikes.
