And on this whole point Steve Pope has made a statement in response, pasted here.....
The Barbel Society's response to the recent article by Martin Salter.
An interesting piece Martin, very well written as always.
Let’s go through it in detail and see what knowledge can really be taken from what is in effect a very limited study.
Also, I must make it very clear I am not one of the doom – mongers that you mention, my personal view sits somewhere in the middle of the spectrum.
I agree that the Angling Press are indeed still featuring reports of large barbel but I would suggest they only tell part of the story. Why would they have succumbed to the ‘otter plague’? They obviously reside in areas where there is a relative degree of safety.
Every barbel angler knows that the situation with regards to barbel populations is different on each river and indeed each venue.
Some rivers, in the main the larger ones, appear to cope reasonably well with an otter population – certainly far better than the smaller ones.
I would imagine the more plentiful and easier to obtain supply of food has something to do with that.
I know it may well have been said but I doubt that otters were going to eat them ( barbel) all, but some will say, and with a degree of justification that they have come pretty close!
Sound Science – now there’s a heading, just what does it mean in this context? I certainly take the view that we need a lot more of it and that includes study in those areas where the otter threat is perceived to be greater than on the Hampshire Avon – once of our premier rivers.
But let’s come to the core of the article, the actual study itself or to be exact; The Importance of Small Fishes and Invasive Crayfish in Otter diet in an English Chalk Stream.
To be more precise we are talking about three sections of the middle reaches of the Hampshire Avon.
You are quite right to mention the Barbel Society as Pete Reading is indeed a valued member who up until recently was our Research and Conservation officer.
Whilst in that position Pete carried out fantastic work that will hopefully have a long term positive impact. I feel it is very important to stress the fact that the Barbel Society wants to see more study in other areas and has total empathy with the anglers whose own fishing has suffered because of the otter situation. We have to show a real understanding of this otherwise far too many anglers feel their concerns are being ignored.
Guess what? I hear you say, but is it any great surprise there were precious few barbel bits found? Without a quantitative analysis of the stretches used, the point is rather lost, indeed Professor Britton practically says so himself in his report.
I do believe it’s condescending to suggest that the science and ‘ evidence’ makes some of your readers uncomfortable, that's precisely the reason it is so difficult to gain more support from anglers and you of all people should understand that. The suggestion implies that the rank and file do not understand - bad PR no matter which way you look at it!
The report states that the spraint analysis gave no evidence but that does not necessarily mean otters do not take barbel. That cannot be overlooked or summarily dismissed.
Far from an ‘Inconvenient Truth’, one could argue that the study is fatally flawed. I come back to the quantitative analysis chestnut.
The report states that the data provides important information for informing conservation conflicts between otter and Fishery interests, I would suggest that only holds true for similar conditions and I don’t believe the Hampshire Avon could be classed as typical.
I’m not a scientist but I think it’s fair to question if the analysis of 140 spraint is sufficient to at least suggest a more general assumption, which the title of the blog actually does.
I then come back to the point about the lack of quantitative data on the barbel population which really is a key issue and I totally agree with Professor Britton’s assertion that this needs to be addressed in any further study if we are really going to understand otter predation.
And finally on the report, I must reiterate that the extent is very limited and that has to be borne in mind. There are a number of statements in Pete Readings inclusion that I would like to pick up on. Pete does make it clear that it is his personal view and that’s important to make clear because of his past position in the Barbel Society. I agree with much of what Pete says but would take issue with some of the words used.
Moribund and tidied up would not sit comfortably with anglers whose venues have experienced, in their eyes, the otter plague.
I would also suggest that large barbel are not being eaten very often because they are not exactly prolific and other sources of food are easier to obtain.
Hunting down big barbel makes sense when that’s all there is!
It is reassuring to hear that Pete believes the Hampshire Avon has a sustainable barbel population, which has to be our goal across the country.
Anglers are notorious for jumping to conclusions but when they form a large number across the whole country then it’s wise to take note otherwise it can come across as I’m all right Jack and I’m sure that’s not the intention.
Empathy and understanding the concerns of fellow anglers is vital.
I hope Pete bears in mind the venue we both fish on the Kennet. This stretch is overrun with crayfish and also has resident otters – it is now practically devoid of any barbel or chub.
Perhaps the study should have taken place there?
In conclusion, the study cannot be seen in isolation. It’s use will be as part of a much wider programme and I hope we can make that happen.
Otherwise the blog gives a very misleading view of a situation that is of great concern to all of us.I hope those who have read the blog do not make base assumptions on what may well be a ‘one off’.
To that end I would say that instead of “inconvenient truths,” a more balanced title would have been “evidence – in question”.
A small part of a very complex case and the jury is still out.
