Every body and there momma from all over come down here to troll it's going to have an effect for sure our lake had a ton of 11" - 12" crappie these last few years since they changed the size from over 10" to over 12" to keep. Last year they went to 11" over to keep. It was a slaughter. They changed keeping 20 to 15 per day or it would have been bad. Bumping up the size definitely helps. They should have left it at 12" I only caught maybe a dozen last year that were under 12". People down here would have a stroke with a one pole rule.
