These are exactly the pellets I have been using for 5 years at least and I have been referring to many on here again and again.
The ingredient list is less than good but one has to understand the purpose of this food - this is to throw into a NATURAL, large body of water to have fish come out and eat and show themselves. This is meant to be very far from a staple food or from accounting for, I'd guess, more than 1/4 of what the fishes eat.
Almost all my fish always liked them but the vast majority of the make-up appears to be of the terrestrial plant origin, like wheat and its derivatives, beans, corn, etc. One of them has hydrolyzed feather as the first ingredient - the Trophy fish one, the indeed stinky and more expensive one
RD is a great expert on these issues and he wrote several articles here on MFK. If one is patient and reads through this, sometimes a bit too heated, discussion, they will pick up a lot of valuable info, including on the anti-nutritional matter in beans, etc. which is no good for fish:

I am too busy/lazy. Could you take a nice clear photo of the ingredient lists and post it, please? I have them in hardcopy but for the discussion sake, it'd be nice to have them handy here. Beware, they are very poorly printed on most labels and often a portion of text is cut off on the right but maybe you will luck out and find nicely printed ones.
Yes, country and agricultural stores carry these, like Tractor Supply Co, Countrymax (in Western NY), and all their competition. Some garden outlets, pond shops, etc. carry them and others.
