I'm guessing it will be unlikely on most rivers before the end of June.

Agree with that also Dave about canoes and there occupants who thrash over the shallow gravels disturbing everything in sight, even walking through them, i have seen it
Hi Dave, It's 5am and the dawn chorus has got the better of me again. But whilst I really appreciate old Issac, his science was sometimes found wanting, but covering eggs was one of his better theories. I guess.Hi Neil,
The chub were getting very excited, perhaps seeing the barbel at it made them a bit frisky !
Seriously though, it's something that I have witnessed in previous years on those same gravels.
If barbel eggs are toxic does that mean we don't have to fret about signal crayfish !

Good point Neil and whilst barbel eggs / roe are flagged up as poisonous to humans I can't find any reference as to their harmful effects on anything else.
Dear old Izaak refers to barbel covering their eggs to prevent other fish from eating them ( third para. )
The Compleat Angler, by Izaak Walton
The search did flag up that between 8000 and 12000 eggs per kilo of fish were deposited which means nature must allow for a fair bit of wastage !

Thie poisionos barbel egg thing, I was under the impression that the roe was toxic to all species, not just man, will have to dig deeper I guess, what else to do at this ungodly hour?
