3.2.4. Dry transport of fish (early 1990s)
Before the 1990s, large amounts of water were used for transporting
fish and fish waste in open drains in the factory floor. The
first CP solutions focused on recycling thewater, but the limitations
of this solution were soon realised. It did not reduce the water
consumption significantly nor the emissions of COD, due to the
contact between fish and water.
