Diurnal variation of moving activity of Japanese spiny lobsters and rock crabs were investigated in small indoor tanks. We modeled the diurnal of variation of light intensity with step-like brightness variation having 12L12D periods. The lobster and the crab movements were detected by measuring tension of wire which hang lobster and crab cage. When the brightness is higher than threshold value of the lobster and the crab, the activity variation of them occurs just in phase with the brightness variation. When the daytime brightness was changed to lower than the threshold value, the variation pattern was disturbed, and their activity was high even in daytime. The threshold value of the lobster was about 2.3 x 10^<-5> lx, and that of the rock crab was about 5.7 x 10^<-3> lx, respectively. We obtained spectral sensitivity for lobster by using this scheme, high sensibility was between 490-520nm with a sharp fall-off in sensibility in 590 nm.Light environments, the spectral irradiance and turbidity of water in the habitat of crustacean decapods were measured in Ise Bay and its neighboring waters. The light at the wavelength 565 nm penetrated to the deepest in Ise Bay while that was at the wavelength 490 nm in its neighboring waters (the open coastal waters).

在室内小型水池中研究了日本螯虾和岩蟹的移动活动日变化。我们用12L12D周期的阶梯状亮度变化来模拟光强的日变化。通过测量悬挂在龙虾和螃蟹笼上的金属丝的张力来检测龙虾和螃蟹的运动。当亮度高于阈值时，龙虾和螃蟹的活动变化与亮度变化是同步的。当白天亮度低于阈值时，其变化模式受到干扰，即使在白天它们的活动也很高。龙虾的阈值约为2.3 × 10^<-5> lx，岩蟹的阈值约为5.7 × 10^<-3> lx。利用该方案获得了龙虾的光谱灵敏度，在490 ~ 520nm之间灵敏度较高，在590 nm处灵敏度急剧下降。对伊势湾及其邻近海域甲壳类动物栖息地的光环境、光谱辐照度和浊度进行了测量。在伊势湾，波长为565纳米的光线穿透最深，而在邻近的水域（开放的沿海水域），波长为490纳米。
