Thanks for your input! Yeah, a balanced and consistent diet with clean water is definitely the keys to growing these fish fast. Largemouth are known to reach around 15 inches in their first year in big ponds with the right genes and plenty of food. I think with my plan I could maybe get them to 20 or longer in their first year which would literally be unheard of. The goal for me is to get a very long fish with a huge frame that will fill out as they slow down in growth after the first few years. I know temensis can hit that with the right conditions for comparison. I will have mine in an outdoor pond that will be 4-6000 gallons once complete and will have plenty of live food such as bluegill, shad, tilapia, trout, crawfish, etc. But, I want to have them be trained to eat from my hand and take some extremely nutrient dense foods that I can personally supply. My current idea is supplementing them with alligator meat stuffed with massivore pellets. Alligator because it is the most protein dense lean meat out there. 46 grams in 3.5 oz of meat with very low fat. Literally could be a super food for these fish to push their growth to the absolute max which is what I am looking at doing.
It's a fine art my friend haha, I got my start keeping largemouth bass and rainbow trout in a 30 gallon ice chest in my garage hand feeding them nightcrawlers. Feeding time was always a blast, especially having them jump for stuff you dangled above em! Progressed over the years to bigger setups... now getting myself in position to grow giants and keep doing it. Bass have an incredible personality that's for sure!
