The long term affects of neonicitinoids is quite well documented. The most sensitive invertebrates will kick the bucket on even a very low concentration (this stuff would wipe out every invertebrate in an Olympic swimming pool with 1 single drop).

On a wild river there are all sorts of variables - if it's a short term pollution some parts of a stream may be passed by - think if you've kicked up some mud wading - the flow will take it away, but it won't fill the river bank to bank. Smaller streams are probably most susceptible to a total wipe out.

The quantity of the pollutant in this particular case seems to have been huge, and downstream of the effected area is thick with it - bank to bank, so there you have the prospect of all life effected (no little back eddy that's passed by...). Invertebrates all react to different pollutants differently. Stoneflies are particularly susceptible to this sort of sewage/slurry damage - they will be gone, and lots of others too. They will take many years to repopulate the stream from up and downstream.

Thanks for that.
It is certainly my understanding of the situation. Do you have any further details of the incident itself?

Local sources are suggesting somewhere between 250,000 and 4 million litres of slurry have poured into the river via a drainage ditch and tributary.

I must stress none of this is officially confirmed at the moment and the investigations are ongoing but it's a massive massive incident.

The media reports of two miles of river being seriously effected are quite conservative. Surveys up to seven miles down river of the incident were showing almost complete fish kills.

Again can I urge all anglers to take less than a minute to do the following...

Last day to respond to WAG's NVZ Consultation.

This is the easiest way...

Can I ask everyone to PLEASE take less than a minute to open the following link, copy and paste Carmarthen Fisherman's Federations brilliant response to Welsh Assembly Goverments NVZ Consultation and email it to water@wales.gsi.gov.uk

CONSULTATION CLOSES TODAY

Interesting.
So were the farmers negligible, or the persons running the plant for the farmers?
It could also be argued that these plants allow farmers to continue to farm intensively (economically) given the onset of NVZs?

Taken from the NFU's "Ambition" paper on AD's

"With income only from the sale of energy (and some additional benefits from the replacement of purchased fertilisers), on-farm AD plants should be subject to ‘light touch’ regulation and ought to be welcomed by local planners (subject to the usual planning process and conditions)"

An interesting read and you wonder where this will all end with Brexit looming
