Yes there is a difference in the interaction. Fish in net pens only compete indirectly with wild fish. They don't compete directly with the wild fish for such things as food, space. Stop and think a minute. 1,700,000,000 salmon smolt were added to the "pastures" in the Gulf of Alaska. These are extra fish above and beyond natural wild production. All pastures have limits, they can only sustain a certain amount of "grazing". Doesn't the figure of 2.7% return worry you? It would be interesting to see if there is any data indicating what the level of return in Alaska is over the last 30 years. Has it been dropping? Maybe that indicates an overgrazing of the pasture?
And there are all the smolt from Russia and Japan. Yes they stock the Pacific for their own commercial fisheries.
Maybe you don't understand how the Alaskans operate? They do a type of Aquaculture called Sea Ranching. I recommend you google a website called:
"The Truth About Alaskan Salmon"
Don't worry yourself about what my agenda is here. I could care less if there is ever another salmon grown in BC. I am happen to believe that aquaculture has a place. I have no problem accepting the sea lice levels can be increased by farms. However I will submit that there are ways to eliminate the impact on wild smolts. Look back a few posts where I outlined how this can be done using a combination of CC farms and short term net pen farms to accomplish both safeguarding the wild smolts and maintaining a level of profitability for the industry. I think this called a win win.
Agent,
Not sure about the Boat Vectors. They certainly have been implicated in such things as Zerbra Mussel introductions among other organisms which hitch a ride in Bilge water. I think it is more CFIA due dilligence to lock down the sites until things can be confirmed or not.
All the disinfection protocols as well as mass mortality protocols are in place for each farm site. Whether or not you have to use them, you have to have the procedures worked out in advance. No good to look for a fish reduction or composter when you have a pile of dead fish to deal with.
Processing plants have waste water treatment systems. Farming companies require these disinfection systems for biosecurity reasons. Plants processing wild fish don't have to have near the level of treatment, and have no disinfection. All the water that is being transported with the fish is contained in holding tanks and treated through disinfection systems. There are various systems availible. I'll try and locate some.
The herring fishery could be just a roe fishery with the carcasses turned into meal as a by product. I doubt they are targetted for meal specifically.
