Bangkokman, don't apologize for the sentence structure, I really do like it. I myself am not the best writer and have wrote much worse than that. In this fish forum we really don't pay too much attention to it.
Anyway, I think we have a misunderstanding.
With any frozen fish food that you buy from a LFS there is no regulation. I have many times bought food that was clearly re-frozen. You can tell especially with mysis as they fall apart in small pieces if this happened. Food for human consumption has higher standards and is not "supposed" to be re frozen.
It unfortunately happens sometimes as my family has been in the sea food business for over 100 years.
But you are correct, human food is most likely taken care of better.
The problem with scallops for human consumption is that they do not sell the entire scallop. That little piece of flesh is just the mussle that closes the shell. Thats why you can't buy them in the shell like clams. If you were to buy whole scallops, they would be an excellent food. Whole Salt water fish, if it is not rotten, re froze or too old, is the best food because if you are feeding a fish, fish flesh has everything the fish needs, because it is a fish.
Almost all of the nutrition in a fish is in the guts. All of the vitamin A, D and E are in the liver which is where Cod Liver Oil comes from, fish livers. I take it myself.
If you were to feed just just the mussle of a silverside, then a scallop would probably be the same thing.
When humans eat fish we just eat the mussle, not the guts, because well the guts are disguesting but when we eat small sardines we also eat the guts which is the reason whole sardines are the healthiest thing we can eat. (I hate them)
