Dave, I'm guessing 2013 by the intern period. Great study, but I'm thinking the Aquamax numbers would be different today.
And IIRC, the current Cargill 1/8' has less than 40% protein right now.
I'm waiting on a reply from Cargill as we speak.
I doubt I'll change from Cargill at this point, because I'm happy with the 4512, but I really like the Optimal evals because of who's doing it. I trust these guys to make a fair and informed decision, and will go so far as to say Tony wouldn't feed free fish food if it didn't achieve the goals he's after. That's about all you can ask of anybody that raises fish.
I've never addressed the Purina issues because I quit feeding it several years ago, but the various problems might turn out to be a very good thing. An opening in any market drives competition, and competition "should" result in more testing, and better products. Optimal seeing an opening in the market is a perfect example of that.
