Refrigerated Sea Water (RSW) For Handling of Fish Catches

Abstract

Most fishermen use ice (icing) as a fish preservative for fresh fish products and use the frezer as a frozen fish product.Handling of fish catches in the sea on fishing boats is the first stage that determines the quality of fish that directly impact on the selling price. RSW to overcome the weakness of the use of ice in the fish preservation on the ship. It’s technique of cooling and preserving fish by inserting fish into a hold or chamber containing cold sea air temperature of about -5C which is cooled manually by a refrigeration system. RSW ship’s does not need to carry ice blocks so as to reduce the cost of supplies, no need to hold a special hatch to ice, fish temperatures fall faster because the cold sea air can enter the fish body, the fish get no pressure because of the buoyancy of the air, durable due to the salting process from the sea air and the quality of the fish remain awake as fresh fish products higher prices.
