Apples and oranges grown in Missouri, an altered river against a man made lake stocked with non-native fish. Not a lot to grasp for comparison purposes.
Beyond the selfish ranting, Missouri's trout programs serve a much more diverse population than Arkansas's ever will. While Missouri has taken advantage of it's many springs, Arkansas has only exploited Mammoth, at least to my knowledge. Again it's different environments, Missouri's cold water resource is naturally scattered and more compact. Arkansas's is man made, or made in Missouri , and individually larger.
Different populations and resources, different tactics.
