The proliferation of pathogenic agents such as Pseudomonas, Aeromonas and Vibrio needs to be controlled and minimised in order to reduce bacterial infections in the water used to transport fish. SAFE TRAVEL is a concentrated suspension of purifying bacteria selected for their capacity to develop in water used to transport fish (oxygenation and temperature, for example) and they do this by feeding on the organic waste produced by the animals. The probiotic effect of Safe Travel prevents the development of pathogens by depriving them of food.
