I recently read about a trick some people use to attract predatory fish. They catch a couple handfuls of minnows, then put them in either a bottle full of holes or something mesh. The idea is to let any predators around see, smell, and hear the minnows, without actually letting them eat any. They end up slinking around the minnow cage hoping for food, and if someone tosses a minnow lure over by the cage, the predators are likely to bite.
This seems like it would work reasonably well. Is it legal in Texas? I can't find anything about it in the handbook.
I've also heard of a thing where someone puts something like a dead squirrel into a mesh bag and hangs it in a tree over the water for awhile. Maggots ensue, and occasionally fall into the water. Fish learn about it, and if you toss a maggot on a hook under it, they'll snag that too. Does anyone know if that's illegal? I'm guessing that might best be done on private land, since most parks probably don't want anyone hanging dead squirrels in trees.
