The effects of orally administrated bovine lactoferrin (LF, 75 mg/kg body weight/day) on growth, survival rate, and mucus secretion on the body epidermis of juvenile ayu, Plecoglossus altivelis, were studied at 12°C for a period of 39 days. Effect of LF on the survival rate of ayu held under deteriorating environmental conditions was also examined. No significant differences in growth and survival rate were found between the control and the LF-treated groups. In LF-treated fish, increased skin mucus secretion was observed. The survival time of LF-treated fish exposed to hypoxic condition, formalin and copper sulfate solutions was longer than that of the control. This result suggests that LF treatment can reduce stress response of ayu held under deteriorating environmental conditions and extend its survival time.
