This research analyzes goldfish’ (Carassius auratus) environmental preference behavior by setting up different environmental color-models to spur goldfish’reactions. It is investigated that pre-conditioned preference of goldfish was stressed by electric shock or high osmotic pressure. We’re interested in how stress experience modulate goldfish’ exploring behavior and its environmental preference. Goldfish that prefers brown-colored environment (compared with white) is suitable for being an model animal to investigate fish’s environmental preference. Both electric shocks and high osmotic pressure, two different kinds of stress, can affect goldfish’ behavior. It shows that fish have the ability to learn and memorize the stress experience. Besides, different stress has different effects on fish’ environmental preference behavior. It proves that there are complicated interactions among environmental stimulus, memories of stress and behavior caused by different kinds of stress.本研究利用環境色彩特徵的差異，建立朱文錦(Carassius auratus)環境偏好行為之動物模式，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，以研究魚類的逆境經驗，是否可形成記憶，並影響其行為。我們發現朱文錦偏好土色環境(相對於白色環境)，適合作為探討魚類對環境偏好的實驗動物。電擊與高滲透壓兩種不同性質的逆境經驗，皆可影響朱文錦的環境偏好，顯示魚類具有記憶逆境環境的學習能力。此外，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。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。
