His particular concern was for the safety of elasmobranchs, as sharks, rays and skates are called collectively.

他特别担心的是板鳃鱼的安全，板鳃鱼是鲨鱼、魟鱼和鳐鱼的统称。

Sharks and rays, known collectively as elasmobranchs, seem particularly vulnerable.

鲨鱼和鳐鱼统称为板鳃类动物，似乎特别容易受到伤害。

Assuming that point is, indeed, proved, SharkGuards may offer a solution to the problem of elasmobranch bycatch.

假设这一点确实得到了证明，SharkGuards 可能会为软骨鱼类兼捕问题提供解决方案。

There will need to be others, in other stretches of water, with different elasmobranchs at risk.

在其他水域中，需要有其他人，不同的软骨鱼类处于危险之中。

Part of the answer to that might be to discourage elasmobranchs from taking the bait without simultaneously discouraging target species such as tuna.

部分答案可能是阻止板鳃类鱼上钩，同时又不阻止金枪鱼等目标物种。

Of the two predominant local elasmobranchs, hooks fitted with SharkGuards caught 91% fewer blue sharks and 71% fewer stingrays (pictured above) than did those without one.

在当地两种主要的板鳃类动物中，装有 SharkGuards 的钩子比没有装备的钩子捕获的大青鲨少 91%，黄貂鱼少 71%（如上图所示）。

Elasmobranchs detect these via organs called the ampullae of Lorenzini, which are jelly-filled receptors scattered around their noses and mouths that serve to sense the electrical fields generated by potential prey's muscles.

Elasmobranchs 通过称为 Lorenzini 壶腹的器官检测到这些，这些器官是散布在鼻子和嘴巴周围的充满果冻的受体，用于感知潜在猎物肌肉产生的电场。
