I know most spots I hit pretty well , that said if I want to keep them I like fat ones and the minimum size is relative , I can fillet a cricket if I want to and want to eat ...so if they are legal and we want dinner I will keep 6 or so on gills around 6 inches or larger and 3 or 4 on crappie above 10 inches ....of course I have ample opportunity to keep fish so in most cases they get a pass from me anyway ...every once in a while I keep a bunch of eaters and fill my freezer and typically they are crappie , but I have been known to spoon a few sunfish and fillet them in numbers to ...
We are real picky about where the fish we keep come from ....Dfw has lots of sprawl and urban run off can be a hazard to the local waters ....lots of lakes have very low recommended consumption amounts ...
