Stress resistance is an important factor determining the post-shipment performance of the fish.
However, insufficient attention has been given to enhancing the stress resistance of the fish to increase their chances of survival after transport. To increase the loading density and reduce post-shipment mortality of ornamental fish, efforts should be made to lower the stress responses of the fish and enhance their stress resistance. As the effects of transport of ornamental fish extend beyond the actual transportation period, emphasis should also be placed on the preparation of the fish for the transport and recovery of the fish after shipment. Control of the stress response of ornamental fish should start on the farm. prophylaxis before capture and minimize stress to the fish during the capture operation. Feeding the
guppy with diets supplemented with vitamin C at 2000 mg kg 1 for 10 days enhances both disease resistance to Tetrahymena and the stress resistance of
the fish, leading to reduced post-shipment mortality.Farmers can contribute by applying nutritional prophylaxis before capture and minimize stress to the fish during the capture operation. Feeding the guppy with diets supplemented with vitamin C at 2000 mg kg 1 for 10 days enhances both disease resistance to Tetrahymena and the stress resistance of the fish, leading to reduced post-shipment mortality.
