It might equally be the effect of a large percentage of the young stock
being eaten and so there is little competition for the (dwindling) food
resource - those adults that do survive therefore grow well.

This is all very well until there are a few hard years in a row when the
populations might be distorted. For eg: How many small tench are surviving?
What about bream?

We know that eels are already under pressure - will this add to the problem?

They have been there for awhile so you would think the
Rivers Authority would have done some studies.

I'm sure someone has looked at it but so far (OK I haven't tried very hard)
I've seen no hard figures.

Like the idea of the lemon but brown bread kills the old tummy and cucumber
repeats so I am guessing a good crusty bit of break and an ice cold cider,
no finesse me.VBG

I'll take my cider at cellar temperature thanks - but use the signals
anywhere a tv cook would use tiger prawns or langoustine** and you won't go
far wrong.

Cheerio,

American signal crayfish

American crayfish in UK streams and rivers are threatening our
indigenous crayfish. Where have they come from and how do they threaten
their native cousins?

A useful page, ta. I'd like to see some figures though - some quantitative
survey(s).

Cheerio,

Imagine: a big, strong, productive, scavenger has cleared a lot of things
Bottom feeding fish are already food, they have to spend a lot of
Fish spawning, perhaps even predators in their own righ

I have not heard of any research on this, but many famous anglers effect seems to indicate that an increase in large river fish eat their signals. They have for some time, so you would think that would do some research rivers Authority.
