it would be too easy for someone to take a piece of fish out of a fast food fish place and have it tested to see what type of fish it is, so I don't think they'd chance it, but you never know. Fast food places like Taco Bell and McDonald's found that out the hard way as far as what they were serving and calling it hamburger.
A lot of places use phrases like "White fish fresh from Alaska", and everybody assumes they're getting Cod, but just by using that slogan it could be several inexpensive fish from the Bering Sea that the meat of the fish is white. They had a big fishing company on "Undercover Boss" that had several huge ships in the Bering Sea, and I'm talking ships with crews that numbered into the hundreds that the ships had their own processing plants on the ships, and they actually showed the fish that is used for that stuff that you see in seafood salad, or in the seafood spread at places like Subway that they called imitation crab meat. That imitation crab meat is actually made out of a fish they catch in the Bering Sea. Actually, when I saw that I was relieved because at least I now know what I'm eating.
I realize most people don't think they have this channel, but it's one of those channels if you looked for it you'd find, and the channel I'm talking about is the "Outdoor Channel", and there's a show on that channel at 10:30 PM Monday nights called "Bottom Feeders", and the show is about the commercial fishing industry in Wisconsin and Minnesota. I learned from watching that show that the lakes and rivers in Minnesota and Wisconsin are full of fish like Carp, Suckers, Sheephead, and Buffalo Fish. These commercial fisherman catch these fish that are all bottom feeders, and are considered a pest fish, so there's no limit on how many they can harvest from the lakes and rivers, and they have trucks with live wells on them that make trips on a daily basis back and forth from Wisconsin and Minnesota to New York City. These trucks can haul like 50,000 pounds of bottom feeders in one load, and all they keep saying on the show is these fished are consumed by the Jewish community in New York City. If you think of it, and have the "Outdoor Channel" the show is actually a pretty good show. The fishermen will put nets out across the lakes and rivers, and have to use electric wenches to pull the nets in they'll have so many bottom feeders in the.
All this talk about fishing I'll have to go out and buy a fishing license and as my dad used to say wet a line. I actually have a decent size pond in the woods about a half mile from my house I can walk or ride my bike to that is full of real nice size pan fish like sunfish, bluegill, and crappie. Very tasty fish filleted and dipped in beer battered and deep fried.
