The growth of flounders was faster under green-light illumination and slower under red-light illumination than that of fish reared under environmental light conditions. Thus, these results suggest that green light stimulates growth, whereas red light inhibits growth of the fish. Melanin-concentrating hormone and melanocyte- stimulating hormone are neuropeptides of the hypothalamo-pituitary axis. Further, these neuropeptides are associated with regulation of food intake. Molecular cloning of the receptors for these neuropeptides was performed in order to accumulate molecular tools for investigating the relationships between photic environment and fish physiology.

与环境光照条件下相比，绿光下比目鱼生长快，红光下比目鱼生长慢。因此，这些结果表明，绿光刺激鱼的生长，而红光抑制鱼的生长。黑色素浓缩激素和黑色素细胞刺激激素是下丘脑-垂体轴的神经肽。此外，这些神经肽与食物摄入的调节有关。对这些神经肽受体进行分子克隆，为研究光环境与鱼类生理之间的关系积累分子工具。
