Great information for all of us on this subject. I agree with Lusk regarding more shallow cover. The most dense products work best for fry like your cedar trees. They will need to be replenished over time. If you begin to add some artificial habitat, over time you will be all set and not have to keep adding. I'm so glad that a specific structure pattern is holding fish well.By creating a triangle you have made a spot on the spot to hold fish. We preach to guys how important it is to be accurate when placing structure. A pile of stuff randomly dropped in an area will not create habitat and fishing oppourtunities as well. Structurespot is a line of products designed to spot each crib as you sink it. Create the shape and density you want and pull free for re-use.
