Services and Infrastructure for Freezer Vessels

Key services and infrastructure for reducing food loss and waste (FLW) associated with freezer vessels include:

  • Properly designed and maintained vessel
  • Freezer equipment suppliers
  • Refrigeration engineering and service providers
  • Packaging/containers (e.g. cartons, polyethylene bags)
  • By-product buyers/market

About 80% of the capacity of a freezer-trawler is used for sorting, processing, freezing and cold-storage on-board, and the catch capacity is limited by the freezing capacity per 24 hours. This fluctuates among the Pelagic Freezer-trawler Association (PFA) member vessels between less than 100 t/day for the smaller ones, up to over 250 t/day for the bigger vessels.  Other fleets’ vessels without freezing facilities can catch a lot more per day – up to 1,000 t/day in some cases.  The ships typically have 35 to 50 people on-board, working four-hour shifts. Depending on the catch and the weather, fishing trips take 3 to 4 weeks.
