我们研究了不同波长的光——蓝色、绿色和红色——对比目鱼鲽（Verasper moseri）身体生长的影响。使用的光源是荧光灯和日光和荧光灯的组合，产生环境光。这些光源用蓝色、绿色或红色滤光片过滤。在实验期间，将鱼饲养在室内水箱中，使用自然温度的流动海水，每天两次投喂商业颗粒，直到饱腹。坦克是白色的。在10月或9月至1月的14周内，鱼暴露在荧光灯（9:15，亮：暗；08:00-17:00，亮）发出的恒定光下，或暴露在环境光下，9月至12月有14周的自然光期。荧光灯光滤过的波长对鱼的生长有影响，即绿光和蓝光下饲养的鱼的总长度（TL； P<0.01）和体重（BW； P<0.01）大于红光下饲养的鱼。相比之下，在过滤环境光下饲养的鱼，在绿光下饲养的鱼表现出更高的TL （P<0.01）和体重（P<0.01），而在其他波长（蓝色、红色和非过滤环境光）下饲养的鱼则表现出更高的TL和体重（P<0.01）。结果表明，一定波长的绿光和红光对牙鲆生长有促进作用，对牙鲆生长有抑制作用。
We examined the effects of different light wavelengths-blue, green, and red-on the somatic growth of the barfin flounder Verasper moseri, a flatfish. The light sources used were fluorescent lamps and a combination of daylight and fluorescent lamps that produced ambient light. These light sources were filtered using blue, green, or red filters. During the experiments, the fish were reared in indoor tanks with running seawater of natural temperature and fed with commercial pellets twice daily until satiety. The tanks were white in color. Fish were exposed to constant light emitted from the fluorescent lamps (9:15, light:dark; 08:00-17:00, light) for 14 weeks from October or September to January or to ambient light with a 14-week natural photoperiod from September to December. The wavelengths that were filtered from the fluorescent lamp light modified the growth of the fish, i.e., fish reared under green or blue light exhibited a greater total length (TL; P<0.01) and body weight (BW; P<0.01) than those reared under red light. In contrast, in the case of fish exposed to filtered ambient light, fish reared under green light exhibited a greater TL (P<0.01) and BW (P<0.01) than fish exposed to other wavelengths-blue-, red-, and nonfiltered ambient light. Our results indicate that flounder growth was modified by certain wavelengths, namely, green and red light, which had growth-stimulating and growth-inhibiting effects, respectively.
