I have been growing feed trained bass to advanced size for sale for 4 years now. The growth rate when it comes to length is no that different from a well managed pond that uses normal forage species. The biggest difference is girth. The feed trained bass will be from 40-70% above average weight. Traditionally that is fat, however there has been some improvements in feed of late and I am seeing more muscle and less fat. Especially visceral fat. In my experance feed trained bass fill a niche in the market. Feed trained LMB can be used in a new pond where you want to catch big bass now and still want to grow forage for later generations. The feed trained bass will not pressure the forage fish anywhere near the way non pellet trained will. Also they are great for adding genetics as larger fish are not prone to predation. But most of the people who buy from me just want to catch lots of big bass now so they stock heavy with my advanced size bass knowing that forage is not an issue.
