Has anyone ever heard of/done this? I'm not sure of the legality of it either. I was cruising around the internet looking at different crappie catching techniques. One site I came across suggested that the first keeper you catch you should hook a line and bobber through the tail and throw it back. The length of line should be relative to the depth of the water.
The theory is that it will swim back to the school and be a visual reference to where the school is. Back away from the bobber and cast towards it to pick up other fish in the school.
Any thoughts? Is that even possible?

Found out that it's illegal in Texas. Not that I would have done it anyway. Why would someone want to do something like that? This guy on the website acted like it was the only way he fishes. Just goes to show you what type of people are out there...

Thats an old trick on the gulf coast for trout. Except they tie a small baloon on a fish and fly it above the water, and follow it around. The best method I have found is to have multiple locations at various depths and , after the first fish ask.. who, what, where, when and why, and duplicate it to the other holes. It almost becomes a game trying to keep on these guys, but they will tell on themselves for long periods of the year.
