Catch-and-release angling is a hugely popular sport, but what happens to non-targeted species (i.e. bycatch) after they are released? Interestingly, American eels seem to be quite resilient following an angling interaction. In fact, it turns out that there is little difference in the outcome between cutting the line and removing the hook when releasing them. Like with all good research, however, more needs to be done—especially in real-life field settings—to know for sure.

鳗鱼对垂钓者的捕捉和释放具有韧性。

捕捞和释放钓鱼是一项非常受欢迎的运动，但是非目标物种（即兼捕）释放后会发生什么呢？有趣的是，在相互影响的互动之后，美国鳗鱼似乎相当有韧性。实际上，事实证明，在切割线和释放钩子时将钩子移除的结果几乎没有差异。但是，像所有好的研究一样，需要做更多的工作-特别是在现实生活中的现场-要确定。
