The challenges of fish transfer Transporting fish from one rearing facility to another poses significant health risks. It has shown clear benefits in facilitating and speeding up skin wound healing through a quicker onset of tissue rebuilding. A feeding trial was conducted in rainbow trout (Oncorhynchus mykiss) to evaluate the effect of the yeast derivative on skin mucous production following fish transfer. In this experiment, the multi-strain yeast fractions fed continuously before dermal wounding promoted early wound healing (Figure 2).
