摘要翻译:
自2006年以来发表的几篇论文描述了磁场对弹性分支的影响,并评估了磁场在减少鲨鱼和人类之间的负面相互作用方面的效用,包括减少副渔获物。其中大多数重复了一个关于弹性分支探测磁场的物理机制的单一未经检验的假设,也忽略了对硬骨鱼磁接收的仔细考虑。已知硬骨鱼中的几种有基于生物磁铁矿的磁接收,而直接磁场探测也在几种弹性分支中得到支持。先前的论文过于狭隘地聚焦于弹性分支的磁接收是基于Lorenzini壶腹的不受支持的假说,这造成了所有硬骨鱼对磁威慑不敏感的印象。然而,基于磁铁矿的磁接收已经在几种硬骨鱼中被证明,并在其他硬骨鱼中得到支持。此外,电接收存在于许多硬骨鱼物种中;因此,应该考虑基于感应的间接磁接收的可能性。最后,据报道,实验证明硬骨鱼物种对磁阻吓剂不敏感,但设计和样本量不足,无法拒绝任何给定物种的磁检测假设。由于阻吓钩技术的采用既取决于对鲨鱼的阻吓效果,也取决于对目标硬骨鱼的阻吓效果,因此在硬骨鱼物种中检测到的假设必须以足够的样本量进行独立测试。

英文摘要:
Several papers published since 2006 describe effects of magnetic fields on elasmobranchs and assess their utility in reducing negative interactions between sharks and humans, including bycatch reduction. Most of these repeat a single untested hypothesis regarding physical mechanisms by which elasmobranchs detect magnetic fields and also neglect careful consideration of magnetoreception in teleosts. Several species of teleosts are known to have magnetoreception based in biogenic magnetite, and direct magnetic field detection also has support in several species of elasmobranchs. The overly narrow focus of earlier papers on the unsupported hypothesis that magnetoreception in elasmobranchs is based in the ampullae of Lorenzini creates the impression that all teleosts will be insensitive to magnetic deterrents. However, magnetite based magnetoreception has been demonstrated in several teleosts, and is supported in others. Furthermore, electroreception is present in many teleost species; therefore, the possibility of induction based indirect magnetoreception should be considered. Finally, experiments reported as demonstrating insensitivity in teleost species to magnetic deterrents suffer from inadequate design and sample sizes to reject the hypothesis of magnetic detection in any given species. Since adoption of deterrent hook technologies depends on both deterrent effects in sharks and the absence of effects in target teleosts, the hypothesis of detection in teleost species must be independently tested with adequate sample sizes.
