Social preference deficiency in cdnf KO adult fish. A, Schemes of visually mediated social preference behavior setup and representative movement traces of cdnf WT and KO fish during 10 min recording intervals. B, Ratio of cumulative duration in the distal, object, and stimulus/conspecific zone. C, Cumulative time spent in the stimulus (conspecific) zone (unpaired t test, t = 2.357, df = 28, p = 0.0257). D, Cumulative time spent in the object zone (unpaired t test, t = 1.156, df = 28, p = 0.2575). E, Cumulative time spent in the distal zone (unpaired t test, t = 2.217, df = 28, p = 0.0349). n = 15/group. Data are mean ± SEM. *p < 0.05 (Student's t test).
