Lots easier to catch a fish if it’s in a cage.
Unfortunately, farmed salmon isn’t as healthy nor is it as good for you
compared to wild salmon. Although the
real danger created by farmed fish is what escaped farm salmon can do to the
wild population.
Salmon farming is only
about four decades old, but it is the fastest-growing food production system in
the world according to WWF. Globally, about 3.5 million tons are caught or
raised each year, and salmon accounts for 17 percent of the global seafood
trade. About 70 percent of the world's salmon production is farmed.
Farm-raised and wild
caught salmon contain the same amount of cholesterol, but wild salmon have half
the fat of farmed in a typical half-filet serving. Farmed fish also deliver
three times the saturated fat as wild. But to feed a growing global population
and provide the omega-3s they need, wild fisheries may not be up to the job.
Crowded conditions in
the pens used for raising salmon provide an ideal breeding ground for sea lice,
which are now invading wild Alaskan salmon populations. Sea lice can be lethal
to juvenile pink and chum salmon. In farms in some parts of the world, a
pesticide is used to combat sea lice that is toxic to marine life and banned by
both the European Union and U.S. Food and Drug Administration.
