Of course aquaculture is improving - it's an industry like anything else that has immense pressure from not only business realities, but activism and demarketing.
Internally, aquaculture will be constantly reducing costs through fuel efficiency, reduced feed intake, more effective fish health options.
Those changes reduce the impact of the operations continually through measurable criteria like usage, deposition, and mortality.
Healthy farmed fish pose little risk to wild fish when contained in properly sited infrastructure.
The fact that our technology and needs as society are being constantly pitted against the reality of nature and the economy means that there will be compromises made, using precautionary reasoning, which allow progress to occur.
The reality of the situation as always falls somewhere in the middle, as AA came close to recognizing here:
"The best one can do is to decrease the number and severity of those interactions if one accepts 1st that those impacts happen and dissect how they happen (pathogens, especially) by allowing independent science to assess those impacts and then adjust your management based on that science.
Ultimately those tradeoffs are a societal decision after that."
Unfortunately, prior to that came this:
"I made up my mind years ago that you cannot mitigate or insulate wild/cultured stocks using the open net-pen technology."
It is this absolutism that prevents a truly respectful and beneficial dialogue IMHO.
"And one of the most unfortunate biases that certain key people in DFO Aquaculture have are that they think that they have a duty to protect the industry rather than wild salmon - and they see themselves as equivalent to a private vet rather than a public employee who's primary duty as legislated is instead to protect the public resources (IMHO). It's an institutionalized bias."
"Don't forget they don't do any defensible environmental assessments including scoping - like other industries. In fact the regulators conveniently & frequently ignore their own science"
"AND they are in key positions to squish inconvenient research, deny data to make good management decisions and collude with industry and occasionally lie - and they do ALL of the above and have for too many years. That's the difference here.
Sort of like dirty cops planting evidence - something most people would be abhorrently against - especially honest cops."
I would suggest that instead of attacking the character of those working in DFO Aquaculture, I would instead focus on the reasons your science fails to line up with Nature.
Try to address the holes in your hypothesis you could drive a herring skiff through.
Ask yourself why the plume modelling doesn't match any observed trends of mortality or returns?
Why is it so hard to prove your case?
Consider that nature manages pathogens through predation and other means and there might be forces at work here that mean your accusations of wrongdoing and malfeasance are misplaced, and that by improving the quality of science regarding aquaculture overall - we may actually find that net pens with healthy, well managed salmon in them can coexist nicely with the healthy, well managed salmon that swim around them.
