Why not lower the number from 7 to 4? You can't tell me that the normal size family can sit down and eat 7 trout at one supper. Also, move the slot limit size down or make the river from say Millers island down a catch and release only section? Or **** give the freezer filler folks the weir pool to catch their dinner and leave the rest of the river alone.
Delayed harvest has proven to work well on many of rivers as well. But with all that said its going to take a lot of work from our local wardens to up hold some of these ideas and with only two wardens covering Anderson county that would be hard to do. In the many many years of fishing the river I have only been checked one time.
