Comment posted FoI by Salmon and Trout Association shows reality of failure on sea lice control in salmon farms by John Sinclair.
“Can someone explain a closed containment system to me? All seems a bit too simple?”
I read some were that this system is used in Canada, I think its like having big swiming pools all closed in, they can be located on land. I will try and find that link. This guy blogs a lot on those issues

Dawnfresh Seafoods trout farms, Loch Awe and Loch Etive
Jim Frame, West Highlands & Argyll Operations unit manager, and I visited the
Dawnfresh Seafoods trout farms at Loch Awe and Loch Etive on 2 May. Alastair
Salvesen, chairman and major owner of the company, hosted this visit.
I found this visit both interesting and useful as Jim Frame flagged these sites as being
much improved and now demonstrating good practice in this sector. Alastair
Salvesen explained the benefits of recent investments in production facilities and
outlined his future vision. SEPA’s Lochgilphead team will continue to work with
Dawnfresh Seafoods to support good environmental performance.

Very well put Dougie, what is free, give all OAP free bus passes, those with bigger incomes we tax more, therefore they still pay for their “free” bus pass. Nothing is FREE, everything has to be paid for. - Struan and then some: the revelation of planned elderly care provision in Argyll and Bute

It is a very serious acusation to accuse people of behaving like the Nazis. My mother lived through WWII and many of the boys she grew up with at her school left to fight the Nazis and many didn’t come back. Recently I spent an evening with her tracing all their graves, so I do not think what she said was done lightly but with a heavy heart. I also stated that the Palestinians are treated badly by other Arabs, this was witness by someone who I have known all my life. The way in which the Palestinians are being treated is wrong, no spin or lies can change the truth, open your eyes.

“only if:
•those existing fish-farms in sensitive locations are relocated away from the wild salmonid rivers
•and, ultimately, the industry moves into closed containment systems.”
Where exactly would the STA have them relocate? Lets have some real geographical examples please?
Can someone explain a closed containment system to me? All seems a bit too simple?

Like I say it all seems all a little too simple.
Be nice to have an ‘independent’ viewpoint without hearing from the same old antis

As far as we understand it, relocation should be a rolling feature of fish farming – regularly moving the cages to different locations to prevent the build up of the sort of faecal and chemical wastes under discussion.
Again, as far as we understand it, there are – or were – requirements placed upon fish farms in planning permissions, for specific periodic relocations. These requirements were simply ignored – to which neglect the Scottish Environmental Protection Agency (SEPA) turned a blind eye.

In theory there is nothing technical to prevent the use of close circuit systems or pump through systems for growing salmon. Pump ashore systems are nothing new and I once visited Harbor Branch in the US which had its whole, large aquaculture site working on a water system where the discharges from the site were actually higher in quality than the water extracted from the river it was sat on.
It would be a relatively simple matter from a technical viewpoint to have an enclosed cage (effectively a large tank) floating in the sea with water being pumped into the tank. As the water is pumped in, it is filtered to remove pathogens and parasites (technically you could have filters so fine they will remove bacteria but more likely a UV system would be used to sterilise the water Salmon and bacterial action on any uneaten food mean that oxygen demand will be high in the tank so either the water needs to be pumped through very rapidly or the water needs to be additionally oxygenated water out must equal water in so the water has to be drained out through a sewage system that can remove solids (at least) from the waste water.
You can have various refinements of this sort of system so you could, say, remove nitrates from the waste water.
The problem is, of course, cost. Pumping water is expensive, oxygenating water (in enclosed systems with high fish densities) is expensive, filtration of water to remove waste products is expensive At a guess, the cost of using systems that would entail minimal impact on the environment would be at least 5x the cost of using open cage systems, even allowing for the improvements in fish health that should arise.
You can see why the industry might not be too keen to embark on a switch to pump through systems. While the industry is not held financially responsible for the economic costs of the difficult to quantify impacts then don’t expect much in the way of innovation in regard to pump through or recirc systems.
