虽然鸟类的磁感受已经得到了深入的研究,但关于硬骨鱼类,特别是非洄游鱼类的磁感受的文献却很少。我们检查了在捷克共和国传统圣诞节销售的普通鲤鱼(鲤鱼)的排列。样本包括对14537条鱼的方位方位的测量,分布在捷克共和国25个地点的80个大型圆形塑料桶中,在2011年12月的7天内进行了817次采样。我们发现鲤鱼在统计上表现出高度显著的自发偏好,它们的身体沿着南北轴线排列。在没有任何其他共同的方向线索可以解释这种方向偏好的情况下,我们将鱼的排列归因于地磁力线。很明显,磁排列的显示是一个简单的实验范例,具有很大的启发潜力。
While magnetoreception in birds has been studied intensively, the literature on magnetoreception in bony fish, and particularly in non-migratory fish, is quite scarce. We examined alignment of common carps (Cyprinus carpio) at traditional Christmas sale in the Czech Republic. The sample comprised measurements of the directional bearings in 14,537 individual fish, distributed among 80 large circular plastic tubs, at 25 localities in the Czech Republic, during 817 sampling sessions, on seven subsequent days in December 2011. We found that carps displayed a statistically highly significant spontaneous preference to align their bodies along the North-South axis. In the absence of any other common orientation cues which could explain this directional preference, we attribute the alignment of the fish to the geomagnetic field lines. It is apparent that the display of magnetic alignment is a simple experimental paradigm of great heuristic potential.
