That's flat-ass ridiculous.
99% of the fresh salmon in American markets is farmed.
If there were no farmed salmon, that demand would still be there.
How long do you suppose salmon stocks would last once the nets closed
every creek from California to Alaska?
Here's a hint: purse-seine fishing is 80-90% efficient. I.e., 80-90%
of the fish trying to get up that stream are caught while the nets are
out. Convolve that with insatiable demand that leads to maximized
fishing time and efficiency, and it's an 80-90% reduction in the
breeding stock. Every year.
Salmon would no longer be food. Many breeds and/or species would
simply no longer be.
There are ways to reduce sea-lice. There's no way to reduce demand for
fish. Except to raise the price. Which is what the progenitors of the
anti-farming movement are really after.
Flat-assed ridiculous is what every "farmed salmon are bad" zealot
turns into when the simple truth kicks their credulousness out from
under them.
