This experimental study focused on the possible deterrent effect of permanent magnets on adult sandbar sharks Carcharhinus plumbeus. Results showed that the presence of a magnetic field significantly reduced the number of approaches of conditioned C. plumbeus towards a target indicating that adult C. plumbeus can be deterred by strong magnetic fields. These data, therefore, confirm that the use of magnetic devices to reduce shark by-catch is a promising avenue.
这项实验研究聚焦于永久磁铁对成年沙虎鲨(Carcharhinus plumbeus)可能产生的威慑作用。结果表明,磁场的存在显著减少了经条件训练的沙虎鲨接近目标的次数,这表明成年沙虎鲨会受到强磁场的威慑。因此,这些数据证实了使用磁性装置减少鲨鱼误捕是一条很有前景的途径。
