The depth to really depends on the water temperature and the depth of the dock, but I like to go about half the depth of the water. But I would experiment and she ...more what works the best
Light line(5 pound test or so), I make the leader line from the bobber about a 1'-1 1/2' and about 6'' from the hook use a little split shot just ...more to get the bread down faster and lastly I like to just use a little thin wire hook. (Eagle Claw makes a good assortment)
hey victor, my best advice for relatively easy fish to catch would be to fish for bluegill. Which are everywhere around docks and structure and what I like to use ...more is bread especially for fishing with the kids or just a little jig like what would be used for perch and things
