In Mo. we have some lakes that allow 9in fish to be kept, I thank a 10in min. should be on any lake and maybe a 12in on some lakes. Most lakes have a 15 fish limit and maybe a 10 or 12 fish limit would help. It is always nice when you can come home with a couple of 12 or 14in fish and as of now 12 and 14in fish are not uncommon but I have never seen the pressure on the lakes as I do now. With the electronics today and more and more people crappie fishing I am thanking it couldn't hurt anything to try this we can always go back if we need to/ JMHO
