Jim - Have you performed any feed trials with sunfish and the Optimal fish food?
No. I have use many brands but we do not like to report them when making comparisons. Science already weak when someone else makes diets, not since also offending manufacturer if their formulation does not do as well as a competitors. We generally characterize feeds based on proximate composition (CP, Lipid, Energy, Ash and Amino Acid Profile and sometime Fatty Acid Profile).
Ideal studies involve diets we make where we know what goes in and control effects of storage which can be more than you want to know.
