We've recently seen the destruction of a well known carp fishery by otters, and they're being sighted almost by the week on different rivers and stillwaters. They're lovely animals but they are also the fox of the waters with their habit of killing for killing's sake and not just for food. I am not for one minute suggesting we kill otters (which are protected anyway), but what the hell can we do about them if they continue to grow in such numbers an increasing number of fish stocks become endangered? What's the answer? Can they be controlled without killing? I'd like to think so.
