I'm new to the BOC and catfishing. I'm a bit confused and need some clarification. When setting a trotline, I understand I need to get the bait down close to the bottom, but I've read several posts that talk about fishing very shallow (2 - 6 ft.) when using jugs. Why do I fish deep with a trotline, but shallow with jugs? Does it make a difference if I'm fishing in a river or lake? Thanks for the help. BTW, I love this website and you all have already taught me a lot.
