isaac,

if you decide on fish traps be sure to check them often. I once set a fyke net (for about a week)that could not be recovered because so many turtles got trapped.

I dont know of anyway to eradicate a crappie population without draining and restocking. If you are not willing to eradicate your fish population get ready for a battle. Crappie can spawn in huge numbers and its difficult to harvest them in sufficent numbers.

What is the average size crappie? How many do you catch on the average?
