I'm trying to get at is conversion rates for LMB when eating a pound of forage of a given species. Which species of forage (Tilapia, threadfin shad, crawfish or bluegill) is likely to give you the biggest pound of gain? I understand lots of variables going into this analysis and we can say it "all depends" . But can anyone boil it down to which of the 4 listed species of forage will (Likely-educated guess) hhave the best conversion rate, without getting into expendable energy to catch it or how much more babies a tilapia makes, or how big the forage is. Its a ROI question.
