It was always Fred Wilton's contention - and I agree with him and Pete is also agreeing (I think) that by using HNV baits any baits that are not eaten by the carp enrich the water itself, leading to an increase in water life and plants etc. due to the added nutrients...

Over a period of time waters greatly benefit from the use of HNV baits...

I also think that when a HNV bait leaves the gut (i.e. is crapped out) by the fish this also contributes to this effect....

I have seen the carp in my own lakes feeding on the excrement of other carp directly as the surplus food is crapped out....
