This idea that Otters are evidence of a healthy river is nonsense. All they indicate is themselves.
In a perfect world a healthy population of fish should be able to support a natural level of predation. That’s the truth. The problem lies right there though, there isn’t a healthy population of fish and it’s arguable as to when this was the case. This seems a point that is unknown or uncared for by then public at large and using the conclusion to prove your methodology, the Otter is bad science at best.
There are many problems that our water ways face, uncontrollable predation is merely one.
