The physiological and behavioural effects and skin damage caused by salmon lice Lepeophtheirus salmonis (Krøyer) infections on sea trout Salmo trutta L. smolts were greater in fish infected with lice 2 wk after seawater transfer than in fish infected 6 wk after seawater transfer. The initial prevalence of infection was 100% for both groups and the intensity of infection decreased significantly with time over 5 wk. Significantly fewer of the fish infected 2 wk after seawater transfer had resumed feeding by the end of the experiment, leading to a loss of body condition. Furthermore, these fish suffered more severe damage to the skin and detrimental changes in physiological integrity than fish infected 6 wk after seawater transfer as a direct consequence of feeding preadult lice, leading to osmoregulatory failure and death. Although this study was carried out in laboratory conditions, results indicate that lice infections may potentially have a detrimental impact on the survival of wild smolts after seawater transfer.
海水转移2周后感染鲑鱼虱（Lepeophtheirus salmonis，克罗耶氏）的海鳟（Salmo trutta L.）幼鱼，其因感染鲑鱼虱而产生的生理和行为影响以及皮肤损伤，比海水转移6周后感染的鱼更为严重。两组的初始感染率均为100%，且在5周时间内感染强度随时间显著下降。海水转移2周后感染的鱼在实验结束时恢复摄食的数量明显更少，导致鱼体状况变差。此外，由于吸食未成熟的虱子，这些鱼比海水转移6周后感染的鱼遭受了更严重的皮肤损伤和生理完整性的有害变化，导致渗透调节功能衰竭和死亡。尽管这项研究是在实验室条件下进行的，但结果表明，虱子感染可能会对海水转移后野生幼鱼的存活产生不利影响。
