So was I untill that as AA says will see what comes out of the PMOs office and what the deputy ministers are doing
Aquaculture improving?..The Fish Farm Thread
- Thread starter islandboy
- Start date
Nice try but sport fishers for the most part will never support open net cage fish farms. Haven’t you noticed all the coho and chinook around since a big slew of farms were closed? Not just a coincidence.

The Impact of Farmed Salmon on Wild Populations

Any farming of high density animals will cause disease out breaks. In the case of chickens how many millions were culled this year due to avian flue?
The chickens are not spreading to wild foul as the are contained in giant barns or buildings.
Now fish farms get disease outbreaks also bit the difference is there is zero containment. If wild fish go by and get infected and die no one know u til we get data on river returns.
Fish farming in a closed containment will reduce the risks but has a cost that big corporations do not want to pay for
The bird flue is spread between wild and domestic stocks. That's why they do huge culls. If you eat any farmed beef, chicken or pork you effect the wild environment. I'm not sure why folks blindly accept those risks but will oppose farmed salmon no matter what they do to change practices. As stated before I have no interests in any game but find these debates interesting. As a side note .... grain farming destroyed millions and millions of acres of habitat across the prairies but .... no concerns raised now.

You're showing far too much common sense Hardy Guy!
The biggest difference between terrestrial farming & salmon farming is that there are typically buffers around terrestrial cultured stocks - fences & often miles of no farming allowed like the brucellosis & Tuberculosis zones between bison & cattle - but not for salmon farming:
and the water is itself a transport vehicle for disease & parasite vectors between wild/cultured stocks. But there is no acknowledgement of that and no environmental assessments to determine that risk & transfer before ONP cages are places in areas that interact with wild salmon. And in the case of BC - some 1000 x more salmon, interactions & risks than the East Coast.
But I guess acknowledging that would be showing far too much common sense...

Salmon Farms Down, Salmon Returns Up
The main migration route for Fraser River and other South Coast salmon was largely cleared of salmon farms by 2020. A few still operate at the north end of Vancouver Island and there’s a problematic cluster of 3 at the entrance to the Broughton, but by and large, the route has been cleaned up...

As you say, HG - realized impacts are tied into OSRs.
In the context of ocean survival rates - from outmigrating smolts to returning adults - there is a tipping point. If a particular run/year/cohort has an ocean survival rate of maybe ~5-7% - they are doing fairly well - the run increases. From something like 2-3% ocean survival rate - the run is just hanging on. Below this (say 1-2%) - it's typically on a steep decline.
At higher survival rates - there is more scope for additional impacts - including those from FFs.
HOWEVER - at say 2% ocean survival rates - any extra impacts become critical. An extra 1% mortality rate (which admittedly sounds innocuous - but doubles the actual mortality) will drive the stock into a steep decline.
That's why (IMHO) the additional mortality from fish farms is not only likely sporadic - but also very harmful when dealing with stocks at risk with low ocean survival rates - & stocks that are adjacent to open net-pen operations.
Over time - the extra mortality from fish farms can drive the "at risk" stock trajectories into a steep decline. The scale of the impacts & locations of wild/cultured stock interactions should also be taken into consideration
There is a tipping point for all impacts : pollution, climate change, commercial fishing , rec fishing, predation, habitat loss, ocean ranching , .. the list goes on and on .... yet the engo crowd are laser focused on fish farms ..... even closed containment.. I don't get it. Chickens , turkeys and even ostrich interact with wild birds daily no outrage there. Your car pollutes fish bearing streams daily. ..... even terrins car.
Farmed production of some fish—and seaweed—is soaring
The amount of farmed seafood we consume—as opposed to that taken wild from our waters—is soaring every year, making aquaculture an ever-more important source for many diets, and a response to overfishing.

Who knew fences stop big wildlife from domestic animals..
Would you like to see some pics of a herd of dairy cows and 70 plus wild elk in the same field within ft of each other?

Stop it, your making to much sense
Hello Chronic Wasting Disease (CWD), Bovine Tuberculosis (bTB), and Schmallenberg virus.
Hello PRv, ISA, IPN, BKD, VHS, Salmonid alphavirus (SAV), Betanodavirus (NV), Aeromonas salmonicida, Yersinia ruckeri, Tenacibaculum maritimum, sea lice & other pathogens.
Glad you recognize the risk and the inadequacy of the ONP technology to separate wild & cultured stocks.
(p.621) The dynamics of infectious diseases in the oceans differ from those on land in several ways (McCallum et al. 2004). First, ocean
environments have fewer barriers to the movement of hosts and pathogens. Second, large migrations of fish are common, and
ocean currents can carry both hosts and pathogens for long distances. Third, common behaviours such as aggregation of fish
hosts in shoals and schools can further facilitate disease spread. As a result of these differences, infectious diseases have rates of
spatial spread in the oceans that are one to two orders of magnitude faster than on land (McCallum et al. 2003). For example,
herpes epidemics of Australian pilchards (Sardinops sagax) in the 1990s (Jones et al. 1997; Gaughan 2001) spread at 10 000 km per
year (McCallum et al. 2003).
Infectious agent release and Pacific salmon exposure at Atlantic salmon farms revealed by environmental DNA - Scientific Reports
The potential risk posed by infectious agents (IAs) associated with netpen aquaculture to wild fishes is determined based on the “release” of IAs from netpens into the environment, the “exposure” of the wild fish to those released agents, and the “consequence” for wild fish experiencing...

Compared to other types of animal production facilities, netpen aquaculture faces enhanced risk for IA
transfer because nets provide no barrier against the flow of water, which can both convey agents long distances3
and provide a matrix within which they may persist
The introduction of large captive populations of domesticated Atlantic salmon, and in some cases Chinook salmon (Oncorhynchus
tshawytscha), into coastal ecosystems inhabited by wild salmon and many other wild fish species, has created opportunities for
novel ecological and evolutionary dynamics of their pathogens (3, 4). The abundance and density of fish in salmon farms present
ideal conditions for the growth of viruses, bacteria, and parasites (4–6) (collectively “pathogens”). This can create a new source of
transmission to wild Pacific salmon that would not exist naturally (6), and the associated risks are likely to be elevated whether or not
a pathogen is exotic. Examples of how salmon farms alter disease dynamics include pathogen introductions, amplification, spillover
and spill-back between wild and farmed salmon (7–9), pathogen adaptation to new hosts (10), and the evolution of drug resistance
(11, 12) and virulence (13, 14). These changes to disease dynamics have impacts on the health (15, 16), growth (17), survival (18, 19),
and recruitment (20, 21) of wild salmon. These pathogen interactions may be a primary mechanism for the association between
salmon aquaculture development and wild-salmon declines observed in Europe, eastern Canada, and BC (22).

And soon there will be no need for open net pens to grow salmon in. https://www.popsci.com/environment/lab-grown-salmon/Farmed production of some fish—and seaweed—is soaring

Not sure if this would be considered aquaculture but it is an improvement IMHO.

I guess in saying this, we would have no reason to go sportsfishing also!?smh
