text: Traditional industries Until the mid-1960s, fishing was seen as Lowestoft's main industry, although from the 1930s the percentage so employed directly and in trades associated with fishing was actually only about 10 per cent. Fleets of drifters and trawlers caught fish such as herring, cod and plaice. Catches have diminished since the 1960s and although 100 boats remained by the 1980s, there are now only a few small boats operating out of Lowestoft, with no large trawlers. By 2011 just three traders remained at the town's fish market, which is under threat of closure due to redevelopment of the port. The Centre for Environment, Fisheries and Aquaculture Science (CEFAS), a large fisheries research centre that is a part of Defra, is still located in Lowestoft.
  Other major traditional employers included Eastern Coach Works and engineering and shipbuilding companies clustered around the harbour. These included the Brooke Marine and Richards shipbuilding companies, which together employed over a thousand men but went out of business in the 1990s, and the Norwich-based engineering company Boulton and Paul. Some shipbuilding and repair still goes on at the harbour.
  Modern economy
  Major local employers include Birds Eye frozen foods, with 700 workers. This has been located in the town for over 60 years. The food-processing company Wessex Foods closed its Lowestoft plant in 2010 after a fire destroyed the factory and it failed to find alternative premises.
