Even this is difficult. The contents on the bag we sell is praticaly the same as GFC. It does not breakdown where the animal protein comes from, fish, chicken, etc. I know lots of reaserch is being done to test differ lipids sources from vegetable source to keep cost down.
I think the only real way to tell is testing each product side by sid and see which produces superior growth results. Until this is done I do not see how a consumer can tell by reading a bag.
Yes Dave there is one out there that is 41% protein but does not smell like fish at all and the fish have low desire to eat it. I told client quit using; switched to 32% protein GFC and fish hammer it.
