The problem is that people get over-enthusiastic about culling them, and people with a dangerous "little bit of knowledge" can end up killing the endangered white clawed crayfish by mistake. In some parts of the country, the EA was issuing free licences to trap them.Another problem with the crayfish is that people use traps to catch them, and then otters get stuck in the traps and die. Try searching on "otter" and "signal crayfish" on google and see the problem. On Thursday I found one of these menaces in my favourite local river (picture attached if I can work the attachments). I'm concerned about them taking off and utterly ruined it, but what can you do.To be honest, I'm really despondent about invasive species. Particularly around the rivers. There's way out of control Himalayan Balsam. There's Japanese Knotweed, which is only patchy, but nothing is ever done about it. And there's floating pennywort. Now, signal crayfish.</blockquote>
