An eight cell multiple-choice experiment was used to investigate the influence of temperature on the locomotor response of goldfish (Carassius auratus) to a chemical feeding cue. When a food extract was infused into a single cell at ambient temperatures of 26, 28, 30, 32, and 34 degrees C (ambient temperature=acclimation temperature) the goldfish spent more time in the extract cell than three similarly outfitted dummy cells at all temperatures, but the intensity of their attraction varied over the thermal interval. Attraction was highest at 28 degrees C and gradually declined to its lowest level by 34 degrees C. Goldfish acclimated and tested at 26 degrees C spent more time visiting a combination of food extract and heated water (H+E) than either food extract (E) or heated water (H) alone. The preference for H+E over H and E increased with the temperature differential between heated and ambient waters. Successive increased in acclimation/ambient temperature (30, 32, and 34 degrees C) extinguished the differences between H+E and H and E but did not eliminate the attraction for the thermal and chemical stimuli, per se. The importance of temperature in the variability of chemoreceptive behavior and the interaction between chemical and thermal stimuli are discussed.
一项八单元多项选择实验被用于研究温度对金鱼（Carassius auratus）对化学喂食线索的运动反应的影响。当在26、28、30、32和34摄氏度的环境温度下（环境温度 = 驯化温度）将食物提取物注入单个单元时，在所有温度下，金鱼在含有提取物的单元中停留的时间都比三个装备相似的虚拟单元更长，但它们的吸引强度在这个温度区间内有所变化。吸引力在28摄氏度时最高，并在34摄氏度时逐渐降至最低水平。在26摄氏度下驯化和测试的金鱼花在访问食物提取物和热水组合（H + E）上的时间比单独访问食物提取物（E）或热水（H）的时间更长。与H和E相比，对H + E的偏好随着热水和环境水之间的温差增大而增加。驯化/环境温度的连续升高（30、32和34摄氏度）消除了H + E与H和E之间的差异，但本身并没有消除对热刺激和化学刺激的吸引力。本文讨论了温度在化学感受行为变异性中的重要性以及化学刺激和热刺激之间的相互作用。
