Black bass have basic biological needs, and scientists have identified the conditions optimum for bass. Logically, then, someone comes along and produces an oxygen meter, color-indicating device, or pH meter; or makes plastic fish habitat; or produces oxygen-chumming equipment. Some of these devices may help bass anglers sometimes.
Bass, though, don’t always seek optimum conditions. Often, they move away from sub-optimum and marginal conditions, but only far enough to meet their minimum needs. They don’t know where anything is in a body of water unless they visit it. Before they choose to use water containing high oxygen levels, an ideal pH, optimum temperature, a concentration of preyfish, or recently added artificial cover, bass must first find it. They aren’t psychic. They can’t guess that somewhere on the other side of…
