For exporters, the visual inspection for pathological problems is not satisfactory, as parasitic infection could be mild and asymptomatic, and the ¢sh may show symptoms only after shipment. Exporters may use the salinity stress test to identify ¢sh lots of good quality for transport to reduce ¢sh loss after shipment. Quality enhancement through health prophylaxis to eradicate parasites would signi¢cantly improve the cumulative mortality of ornamental ¢sh at 7 days post shipment. A new treatment protocol involving treatment in pre-packaging and actual
transport water has been developed to eliminate the need of tank maintenance, thus leading to a saving in manpower and space. Recent experiments using guppy suggested that starvation for 1 day is e¡ective in enhancing their stress resistance. The ¢sh should be starved for an optimal duration only, as prolonged starvation leads to a decrease in the stress resistance
of the ¢sh. A low concentration of salt should be used to enhance the stress resistance of guppy, both in the transport water and in the recovery water after shipment.
High salinity should be avoided as the salt content reduces the e⁄ciency of clinoptilolite and lowers the quality of transport water.
