Understanding Bass metabolism can tell us a lot when it comes to targeting both largemouth and smallmouth bass. Looking back on my first days of Bass fishing, I can remember how simple my thought process was... choose a lake, bring my favorite rod, favorite lure, and try to catch fish. I never considered; time of year, water temperature, weather changes, oxygen levels, water clarity, water depth, pressure changes, location of baitfish, and all the other variables that play an important role in Bass fishing.
