研究了Li对鲫鱼（Carassius auratus）个体和群体生理活动节律的影响。单独控制的金鱼在恒定的光照下显示出稳定的自由运行的昼夜活动。当被放置在20条鱼的群体中时，它们的昼夜节律活动表现出社会促进作用，群体昼夜节律周期明显长于单个鱼。长期使用氯化锂（15 mmol/l）治疗可显著延长个体的昼夜节律周期，并消除群体形成对昼夜节律活动的社会促进作用。
The effects of Li on the circadian activity rhythms of individual and groups of goldfish, Carassius auratus, were examined. Individual control goldfish display stable freerunning circadian activity under constant illumination. When placed in groups of 20 the fish show a social facilitation of their circadian activity with a significantly longer and more stable group circadian period than that shown by individual fish. Chronic treatment with lithium chloride (15 mmol/l) causes a significant, reversible, lengthening of the circadian period of individual fish and elimination of the social facilitation of circadian activity by group formation.
