So take out all Bass? Or just the ones under 10in?
Neither. Just take out all the LMB that are under 90% relative weight.
"How do I figure that out" will be the next question (I assume).
To answer that, you will need a digital scale, a ruler, a calculator and a copy of
this chart.
Take the LMB that you catch. Get it's weight, remember it and measure it's length. Find the fish that is that long on the chart. See that weight that is associated with that length fish? Take your fish weight, and divide that by the weight that is on the chart. What is the number? Under .9 and remove it. Over .9 toss it back in.
