D10, I am going to go out on a limb here and you correct me if I'm wrong-

I have a hard time believing that any amount of pressure ona lake as productive as Nimrod, Overcup or Conway can really reduce the numberof crappie caught.
Take a typical day in the spring or fall on Conway:
45 boats x 15 crappie kept= 675 crappie.
This probably happens for 100 days of the year. So, 67,500crappie.
Then add in the 50% of that caught during the rest of theyear, so you are at an annual total of appx. 101,250 crappie caught every yearon the lake.
The crappie in Conway are less numerous that in Nimrod orOvercup and still probably number in the millions- so less that 10% or even 5%attrition to the population via fishing pressure.
