In this research, we investigated the interactions between goldfish’ (Carassius auratus) sensory experiences (electric shock, high osmotic pressure and colors). We separated the sensory experiences into two parts. One of them, we used different kinds of environmental color-models to analyze goldfish’s environmental preference behavior and different kinds of stress experience(electric shock and high osmotic pressure) to build the animal model of environmental preference behavior. We found that goldfish prefer brown-colored environment (compared with white) and different
stress has different effects on fish’s environmental preference behavior. It proves that fish has the ability to learn and memorize the stress experience and shows that there are complicated interactions among environmental stimulus, memories of stress and behaviors caused by different kinds of stress. Also, we investigated the interactions between spatial memory and color distinction. We measured the duration of goldfish getting through the color-marked barriers driven by regular electric shock. We found that goldfish spend less time to get through color-marked barriers than those unmarked. It shows that there are some interactions between spatial memory and color distinction. In conclusion, the research proves that different sensory experiences can affect goldfish’s behaviors.本實驗利用感官經驗(電擊、高滲透壓、色彩)，探討與朱文錦(Carassius auratus)行為調控的交互作用。我們將感官經驗分成兩模式：利用環境色彩特徵的差異，探討不同逆境刺激經驗(施予電擊或高滲透壓環境)，與魚類環境偏好行為的交互作用，建立朱文錦環境偏好行為之動物模式。我們發現朱文錦偏好土色環境(相對於白色環境)，而不同性質的逆境經驗，對魚類的環境偏好行為具有不同的影響，顯示魚類具有記憶逆境環境的學習能力，且證明「環境刺激—經驗(記憶)—行為表現」三者之間具複雜的交互作用。另外，我們亦探討空間記憶與色彩辨識的交互作用，利用規律的電擊刺激使朱文錦通過有色彩標示的關卡，以研究色彩差異與空間變化對朱文錦通過關卡能力的影響。我們發現色彩的標示可降低通過關卡的時間，且不同的色彩具不同程度的效果，顯示空間記憶與色彩辨識具交互作用。本實驗證明了不同的感官經驗或刺激，對朱文錦的行為調控具質與量的差異。
