500	0		_aOver the last decade Australia's northern prawn industry has grown from a small beginning to one of the country's major export industries. During this period it has undergone vast technological changes particularly in the areas of handling and storage of raw prawns. Mechanically refrigerated seawater tanks have replaced the less efficient ice storage tanks and in more recent years, more and more vessels are freezing their catches at sea and storing them in refrigerated hulls. These advances have reduced the handling of prawns but only to a certain degree reduced the problems that develop in raw prawns and in particular the major problem, black spot, still remains. CSIRO's Division of Food Research has been studying black spot in an endeavour to find ways to combat it. Of the many chemicals tried, sodium metabisulphite has been the cheapest and most successful.
