根据保护性相似的标准，对鲑鱼的颜色和行为的隐秘假说进行了评估。对文献的回顾表明，鲑鱼的颜色和行为符合一种神秘的解释。对Coho鲑鱼、O.kiutch、PARR底物颜色偏好的实验表明，适当的背景选择的行为相关性是令人满意的。鱼和实验底物透光性的吸收光谱表明，背景匹配是通过银边和PAR标记对波长的消色反射和吸收实现的。
The crypsis hypothesis of salmonid parr coloration and behavior is evaluated in light of the criteria for protective resemblance. A review of the literature indicates that salmonid parr coloration and behavior correspond to a cryptic interpretation. Experiments on coho salmon, O. kisutch, parr substrate color preference indicate that the behavioral correlate of appropriate background choice is satisfied. Absorption spectrophotometry of diapositives of fish and experimental substrates suggests that background matching is achieved through achromatic reflectance and absorption of wavelengths by the silvery sides and parr marks, respectively.
