Fascinating thread that i have just picked up on...Graham has alluded to a point I was going to make. I wonder how many of us would have caught a double figure barbel if we had been fishing in the 1950's, very few I suspect because...well there may have not been that many but why? A number of us have been fortunate enough to live through a barbel explosion, with some fish reaching a size that if it were human would be classified as obese. It is not surprising, therefore that barbel, like carp, are an appropriate and relatively easy food source for such a predator. If there is an apex predator in the system it is bound to have an impact there is no question about this but over time an equilibrium will be reached but there will be fluctuations; simply though this will mean less barbel.I certainly realise how lucky I have been over the years regarding the numbers and quality of barbel that I have seen in most of my rivers.
From the times in the very early '60's when to many they were considered so rare that hardly that many fished for them.
It will be a long time if ever till the fantastic days of the 1970 through to, say 2010 come again
It is obviously heresy to say this on here but maybe the apparent dominance of barbel on many rivers is actually sign of an ecosystem out of kilter and there needs to be balance of all species at the different trophic levels. I do not know, and there is not that much science it seems on what the climax community of a river actually looks like.
Slightly less serious, do otters eat bream as i would have thought they were also relatively an easy capture but no one ever seems to mention this...are barbel easy prey as they are generally bottom dwellers that can be attacked from behind?
