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.

在绿灯照明下，比目鱼的生长速度要快，在红色照明下，比在环境光条件下饲养的鱼的生长速度较慢。因此，这些结果表明绿光刺激了生长，而红光抑制了鱼的生长。黑色素浓缩激素和黑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。进行这些神经肽的受体的分子克隆是为了积累分子工具来研究光子环境与鱼类生理学之间的关系。
