摘要
鲑点石斑鱼(■ )具网膜运动反应。引起鲑点石斑鱼视网膜黑色素颗粒明显迁移的照度阀值上限为10^(-1)1×,而视链细胞明显伸缩的照度阀值上限为10^(-2)l_x以上。大弹涂鱼(Boleophthalmus peetinirostris)视网膜在完全暗适应及不同照度(10^(-2)、10^(-1)、10~0、10~1、10~2、10~3lx)下明适应后,并不产生网膜运动反应,推测系通过瞳孔运动反应调节明暗视。
The histological study showed that there is a retinomotor respooae in the retina of Epinephelus fario.The upper limit of the threshold under which the pigment granules of REP remarkably migrate is 10-1 lx,and 10-2 lx for the contract of the cones. No retinomotor response was observed in Boleophthelmus Pectinirostris. The states of retina of fishes exposed to different ambient light intensities (10-2,10-1,10,101,102,103,lx) are the same as that of a dark-adapted fish. Perhaps,a retina of the fish transmits from dark-to light-adaptation by the pupillary respomse
