We examined the effects of tank color and stocking density on the growth of spotted halibut ( Verasper variegatus ) under a green light-emitting diode (LED). Fish reared for 40 days under a green LED (10 μmol m –2 s –1 at the water surface) grew faster than those reared under a white LED, irrespective of tank color (white or black). Green light promoted higher growth than indoor room light when fish were kept for 32 days under both the tested stocking densities, 4.3 kg m –2 and 13 kg m –2 , but stocking density alone did not affect fish growth. These results suggest that a growth-promoting effect of green light can be expected within the range of stocking densities applied here for fish housed in both black and white tanks.

绿光对斑比目鱼促生长作用的评价及其在水产养殖中的实际应用

我们在绿色发光二极管 (LED) 下检查了鱼缸颜色和放养密度对斑点大比目鱼 (Verasper variegatus) 生长的影响。在绿色 LED（水面 10 μmol m –2 s –1）下饲养 40 天的鱼比在白色 LED 下饲养的鱼生长得更快，无论鱼缸颜色（白色或黑色）。当鱼在测试的放养密度 4.3 kg m –2 和 13 kg m –2 下饲养 32 天时，绿光比室内室内光促进了更高的生长，但单独放养密度不影响鱼的生长。这些结果表明，在此处适用于黑色和白色水箱中的鱼的放养密度范围内，可以预期绿光的生长促进作用。
