N2  - In this study, conducted in collaboration with the Western Australian rock lobster industry during the 1992&#8211;93 fishing season, daily records were made on morbidity and mortality of western rock lobsters, Panulirus cygnus, held in commercial shipping (export) cartons. The aims were to measure the rates of morbidity + mortality and to identify patterns of correlation of morbidity + mortality rates for a range of environmental variables recorded by the processors. In three processing units, the rate of morbidity + mortality in simulated live shipments averaged 5&aacute;2% (&#177;0&#183;6), with a highly significant difference (P&#60;0&#183;001) between processing units. Three factors, holding time in export cartons, ambient temperature within the export cartons and chilling period before packing lobsters, had the greatest influence on the rate of morbidity + mortality. Morbidity + mortality rate of animals held for 30&#8211;36 h (10&#183;4 &#177; 2&#183;3%) was twice that of animals held for 20&#8211;24 h (5&#183;2 &#177; 0&#183;6%). A positive significant correlation (r = 0&#183;25, P = 0&#183;001) was identified between morbidity + mortality rate and the internal carton temperature. Aprolongation of the chilling period was reflected by improved survival, possibly resulting from an anaesthesic effect of the chilling treatment.
