Why do we have salmon hatcheries all over the US, but our grocery store only carries imported salmon?

Currently populations of salmon, steelhead, and trout are listed as endangered or threatened in the state of Washington.

The wild Atlantic salmon is gravely endangered on both sides of the Atlantic. Populations of these remarkable fish are at their lowest point in recorded history and catches have declined precipitously.

Most of the salmon I see at the store is wild alaskan...this is not imported. In fact I dont think I have ever seen imported salmon.

Why does Wall-Mart which is made in America sell mostly cheap shoddy Chinese made junk?

For the same reason: Americans are dunces.
