13.1.2 Fish packaging system

Packaging of fish in polythene bags filled with water that is pretreated with chemicals and over saturated with pure oxygen. After packing, bags are placed in a Styrofoam box to provide thermal insulation to prevent sudden change in temperature of the transport water. Fish loading density depends on the transit time (eg. The transit time from Singapore to Europe is 30 hours). The fish loading density (Biomass/g) per unit volume of water (L) increases with increasing body weight. As large fish consume less oxygen and produce less nitrogenous wastes per unit weight than small ones.
