Here is the reg:
-------
• Sport Cast Nets: Maximum sport cast net size is 20 feet in diameter with maximum 1-inch bar mesh statewide except in the following waters. Sport cast nets prohibited in: 1) lakes having fewer than 500 surface acres, 2) any of the streams and tailwaters listed in the “Trout Waters” section of this guide, 3) tributaries of the Cumberland River between Wolf Creek Dam and the Tennessee state line except Crocus and Marrowbone creeks where sport cast mesh size must be made of 1-inch bar mesh only, 4) from the mouth of Crocus Creek upstream for 50 yards. All sport fish incidentally taken while capturing live bait with seines, dip nets or cast nets must be released imme- diately unharmed into the water.

To me this reads that you have to use a net with one inch mesh. Is that new?
You can only throw a new within fifty yards of the mouth.
Bar mesh I am assuming is the mesh size when stretched to form a square pattern?
