Explains why ice is the best means of cooling fish, outlines the methods of manufacture of block ice and different types of small ice, and emphasise that for ice to be effective it must be ice and not a mixture of ice and water. The properties of crushed block ice, flake ice and tube ice are discussed and compared, with brief reference to seawater ice. Read in conjunction with Notes 15 and 68. The information presented is relevant to many Notes in the series in which aspects of chilling are discussed. Measurements are given in British units; Note 40 gives conversion factors to SI units.
