Take a swim under one. Matter fact take a camera.
Post on here.
Does it look any thing remotely close to natural environment. NOT.
Matter of fact... Why is it so many prawn and crab fishers have packed up and move elsewhere?

Sea side Net Pens are destroying all things natural. In around and below all these farms period.

Looking forward to your pics Birdy.

would a video from the lease holder prior to putting a farm in place work for you? or will you simply ignore it?

Fill your boots... How about before and five years after... That should work.

Any if you that can think these farms are GOOD for the environment and our oceans ..... Please post how they are GOOD for our Wild Runs. And how they contribute to the betterment of tge Oceans Health.

Nope, nothing wrong here. I have seen first hand how the BC Govt. and DFO hide, obscure, twist, manipulate info and data to the direct benefit of the net pen industry. To say it doesn't happen is to just promote one's ignorance and naivety.

This is no different than what other govt. depts. have done to protect logging, mining, oil, food, pharmaceutical, etc. Profits and jobs before the environment. Same old story/bulh!t, just an different industry to protect from concerned citizens.
 
Let's see how the FF supporters spin this research...

Given its high prevalence in net pen salmon, debate has arisen on whether PRV poses a risk to migratory salmon, especially in British Columbia (BC) where commercially important wild Pacific salmon are in decline. Various strains of PRV have been associated with diseases in Pacific salmon, including erythrocytic inclusion body syndrome (EIBS), HSMI-like disease, and jaundice/anemia in Japan, Norway, Chile and Canada. We examined the developmental pathway of HSMI and jaundice/anemia associated with PRV-1 in farmed Atlantic and chinook (Oncorhynchus tshawytscha (Walbaum, 1792)) salmon in BC, respectively. In situ hybridization localized PRV-1 within developing lesions in both diseases. The two diseases showed dissimilar pathological pathways, with inflammatory lesions in heart and skeletal muscle in Atlantic salmon and degenerative-necrotic lesions in kidney and liver in chinook salmon, plausibly explained by differences in PRV load tolerance in red blood cells. Viral genome sequencing revealed no consistent differences in PRV-1 variants intimately involved in the development of both diseases suggesting that migratory chinook salmon may be at more than a minimal risk of disease from exposure to the high levels of PRV occurring in salmon farms.[/URL]

As you can see nothing grows in 300'. The video also shows no need for a 5 year vid....
But


As far as your questions about ocean health. the NOAA publishes several docs explaining the environment., this is one of the docs. If you are still curious after. There are more in depth publications explaining aquaculture within there site. https://www.fisheries.noaa.gov/aquaculture/nutrient-impacts-finfish-aquaculture

Good find Bones. You actually found some thing alive under the farm. Must have been mighty deep or new.

Read the report you yourself supplied...... Takes 2 years to get back to pre farm.

Pathetic attempt to hide what you know is Destroying Wild Runs and every thing else.

I hope your proud one day to say to your grand kids ..... Yup i supported the demise of Wild Salmon. Good on ya .

I really do not understand your comment, you asked for pictures showing how a farm is killing the ocean floor. I showed you a video before the anchors go down, there's nothing there. YOU ASKED FOR THE PICTURE AND I gave it to you. Now your personal attacking me WOW. what's being hidden? It's all there on video, nothing basically lives on the ocean floor past 140' there no light.

you left out a few words in your quote... here ill fix it for you

Viral genome sequencing revealed no consistent differences in PRV-1 variants intimately involved in the development of both diseases suggesting that migratory chinook salmon may be at more than a minimal risk of disease from exposure to the high levels of PRV occurring in salmon farms.
 
Had been pretty quiet on the FF threads lately so haven't been spending too much time here. I see things have started up again and it didn't take long to get back into the mode of calling out of each others numbers, science and now fake photos too. Oh, and let's not forget the odd personal swipe thrown in to really get the fight going. Maybe we should start one thread for the pro side and one for the anti side where no one who opposes what is being posted is allowed to add a comment. That way you all could say what you want and avoid the inevitable fights, we wouldn't have to waste any time cleaning up the mess and no one would get banned. This would work, because neither side is ever going to believe the other sides data or opinions, so there is NEVER GOING TO BE A SCENARIO WHEREBY SOMEONE IS CONVINCED TO CHANGE CAMPS.
Excuse the jaded remarks, but seriously, it is like supervising a school yard at recess.
 
The growing body of research is not boding well for net pen salmon farms. Just a matter of time and more research to push these net pens onto the land where their negative impacts can be better managed!

Given that P. orthoreovirus Strain PRV-1 causes HSMI in farmed Atlantic salmon, and likely causes jaundice/anemia in farmed chinook salmon, the absence of consistent sequence variation within PRV-1 in diseased Atlantic and chinook salmon implies a risk of transmission of the virus from farmed salmon to wild Pacific salmon.As Atlantic salmon accounts for 97% of the total biomass of farmed salmon in BC, answering the question of whether the virus causing HSMI in Atlantic salmon causes disease in Pacific salmon is critical when assessing risk. PRV-1 occurred in 65%–75% of farm audit samples of Atlantic and chinook salmon, with approximately 25% of the salmon having high viral loads. In farms where HSMI disease ensues, BC Atlantic salmon show a morbidity rate (i.e., presence of histological lesions) of >80%, similarly to that reported in Norway (Kongtorp et al. 2004a; Kongtorp et al. 2006), and retain high loads of the virus and evidence of inflammatory lesions for a prolonged period of time (over 11 months in the study by Di Cicco et al. 2017). Hence, the environmental footprint and potential for viral transmission to wild salmon from disease-impacted farms is likely high. Although neither disease has yet been identified in wild fish to date, given the high sensitivity of the molecular viral disease development tool to early developing disease states, and of ISH to localize the virus across tissues, we can now apply these approaches to empirically determine whether any evidence exists that PRV-associated diseases may be occurring in migratory salmon in BC.


HSMI is one of the most common infectious diseases of Norwegian farmed salmon (Garseth et al. 2017). Moreover, disease modeling has identified that fish farming intensity in a region is a major risk factor for HSMI outbreaks (Kristoffersen et al. 2013; Morton et al. 2017) suggesting that water-borne transmission may be an important factor in the spread of disease (Hjeltnes et al. 2016).These data also suggest that farming intensity could enhance the exposure of migrating smolts to PRV (Garseth et al. 2017). Escaped farmed salmon, which are most often infected with PRV, could also be a transmission vector for freshwater infections in wild fish if they enter rivers (Madhun et al. 2015; Hjeltnes et al. 2016, 2017). Importantly, there have been recent reports of HSMI outbreaks occurring in freshwater hatcheries in Norway, which represents a shift in what was considered until recently a disease restricted to sea net pens (Hjeltnes et al. 2016, 2017). There is also some indication that PRV infection in freshwater may be associated with earlier and more significant HSMI outbreaks in sea net pens and, as a result, some farmers are attempting to produce PRV-free smolts (E. Rimstad, personal communication, 2017; Hjeltnes et al. 2017).


Prevalence of PRV is low (<3%) in wild migrating BC chinook and sockeye salmon (Oncorhynchus nerka (Walbaum, 1792)) smolts that have not been exposed to salmon farms (Siah et al. 2015; Morton et al. 2017; Purcell et al. 2018; Tucker et al. 2018). Higher prevalence is observed in fall, especially in chinook salmon on the west coast of Vancouver Island that remain resident in the same bays and inlets occupied by salmon farms for prolonged periods of time (up to a year) (Tucker et al. 2011, 2012). An epidemiological study is currently underway to assess the role of salmon farms in the transmission of PRV to wild stocks, based on both patterns of prevalence distributions and full genome sequencing of the virus across farmed and wild populations over multiple years and geographic locations.

More diseased fish to be culled. I wonder if they sell them to the public when they are culled. https://www.undercurrentnews.com/20...ts-another-cooke-salmon-farm-in-newfoundland/
 
Federally fish farms will be regulated based on what people on this east coast think of them not the west coast. Seems to me that some of the major fish farm producers are out of the east coast as well.

Or they may just do what our provincial government has done and allow First Nations to regulate the farms in their territory.

Eather way it seems like a lot of change is going to happen. Something most people want.

Most of the biggest ones (Cermaq, Greig, Marine Harvest) only operate in Canada on the BC coast. The feed companies operate on both coasts, and of course Cooke is very big and has extensive east coast operations and in Washington state. Cooke has been the greatest asset for anti-salmon farming sentiment on the West Coast with their numerous violations of WA guidelines and negligent maintenance practices that have resulted in escapes, esp the huge one last year which was ridiculously blamed on the eclipse. They will now be phased out of WA waters and they serve as a good example to remind us corporate interests only have the corporations $ interests at heart. The employees (other than executives), the environment and the communities they operate in don't matter a damn to them. Only profits and share price matter.

They will be setting up big time in Newfoundland..are there any "first nations" there to deal with?

I’m pretty sure Cooke is looking into farming sablefish and chinook out of Washington state. Only farming Atlantic’s have been banned.

Will see what happens but I wouldn’t write them off.

Like you said they are large corporations that only care about shareholders and profits. That is the function of the board once they go public.

I think we’re more likely to see regulation that smolts must be PRV free when entering ocean pens before we see an out right ban. We are also likely to see them moved from migration areas.

We had an ndp/green government provincially and the most they wanted to do was kick the can down the road and hand it over to First Nations.

I just don’t think they are gonna ban them. Sorry to bust everyone’s bubble.
