| 中文摘要: |
| 选取斑马鱼和蓝鲨为代表，设计并改进了一系列味觉行为学实验方法来探索鱼类的味觉感受。结果表明，斑马鱼和蓝鲨除了具有对苦味和鲜味的感受外，很可能具有对脂肪酸的味觉感受。研究发现，蓝鲨对甜味具有偏好性，这与斑马鱼无甜味感受能力的报道不同。 |
| 英文摘要: |
| In humans (and probably other mammals)，it is generally agreed that there are five basic taste qualities: sweet, bitter, umami, salty and sour. Recent compelling evidence from rodent and human studies raise the possibility for an additional sixth taste modality devoted to the perception of lipids (fat taste). It has been shown that zebrafish can perceive amino acids, bitter tastant as taste stimulants，then what about fat taste?Until now，it has not been reported yet. Based on this, behavioral experiments were conducted to detect the existence of fat taste in Danio rerio and Pangasius sutchi. It was shown that fish can perceive not only bitter and amino acids tastants, but also fatty acids. In addition, we found that P. sutchi had a preference for sweet taste, which is inconsistent with the previous report that there was no sweet taste in zebrafish. |
