Adaptation of brown trout to a black or white background had no statistically significant influence on the activity of the pituitary-interrenal axis in unstressed fish, in fish under conditions of mild chronic stress, or in fish under conditions of severe, acute stress. This finding is in contrast to several other studies on salmonid fish in which background color adaptation has been shown to modulate the pituitary-interrenal response to environmental stress. It is argued that these differences in results may be related to the prior history of interrenal activation in the experimental fish and that in previously unstressed brown trout the activity of the pituitary-interrenal axis is independent of melanotroph activity in the pars intermedia when fish are exposed to subsequent stress.
将褐鳟置于黑色或白色背景下，对于未受应激的鱼、处于轻度慢性应激条件下的鱼或处于严重急性应激条件下的鱼，垂体 - 肾间轴的活性均无统计学上的显著影响。这一发现与其他几项关于鲑科鱼类的研究形成对比，在那些研究中，背景颜色适应已被证明可调节垂体 - 肾间对应激的反应。有人认为，这些结果差异可能与实验鱼肾间激活的既往史有关，并且在先前未受应激的褐鳟中，当鱼暴露于后续应激时，垂体 - 肾间轴的活性独立于垂体中间部的促黑素细胞活性。
