re: Anyone know anything about artificial fish habitats to attract fish?

5 gallon bucket with PVC sticking out is what we have used. USe sandpaper to rough up the surface of the pvc. This helps mor algea attach = more bait fish = more bigger fish.

With the Christmas tree, we have always cut section of branches out to make holes to increase habitat. You can either weight them down and sink away from the dock or attach a line to the dock, add tree, cinder block weight on other end of tree and then suspend the tree vertically.
